ACE Research Area:
Electric Power System Design
Table of Contents
Starting in the mid-nineteen nineties, the U.S. electric power industry has undergone substantial changes in both its structure (ownership and technology aspects) and its architecture (operational and oversight aspects).
During the early years of this restructuring, these changes largely consisted of efforts to move the industry away from highly regulated markets with administered cost-based pricing and towards competitive markets in which prices more fully reflected supply and demand forces. The goal of these changes was to provide industry participants with better incentives to control costs and introduce innovations.
These early restructuring efforts were controversial and difficult. The meltdown in the restructured California wholesale power market in the summer of 2000 -- due in part to market manipulation by Enron traders -- demonstrated what could happen when newly proposed market designs were implemented without sufficient pre-testing. Following this California crisis, many electric power system researchers stressed the need to combine sound understanding of physical electric power system operations with careful economic analyses of incentives in order to develop electric power system designs with good real-world performance characteristics.
The primary goal of this resource site is to encourage the development and study of electric power system designs from a perspective that adequately addresses both economic and engineering concerns.
In accordance with this goal, stress is placed on research making use of powerful
agent-based computational platforms.
These platforms, particularly in co-simulated form, permit electric power systems to be studied as evolving networks of system operators, producers, traders, and customers learning to operate through time over realistically rendered transmission and distribution grids.
- Can agent-based computational platforms facilitate the progression of electric power system designs from conceptualization to practical implementation?
- What form should wholesale power markets take? To what extent should regions be permitted to design their own wholesale power markets rather than adhere to a single standardized design, such as the Standard Market Design (SMD) proposed by the U.S. Federal Energy Regulatory Commission (FERC) for U.S. wholesale power markets?
- How should electric power system designs handle network constraints, network congestion, and the allocation of network service and investment costs at high-voltage transmission levels? at lower-voltage distribution levels?
- How important is the active participation of distributed power resources and/or end-use customers for the effective functioning of electric power systems?
- To what extent can strategic participants "game the system" under currently implemented electric power system designs?
- To what extent should oversight agencies and independent entities be tasked with the top-down regulation and management of electric power system operations in an attempt to ensure the efficiency, reliability, and resiliency of these operations?
- Are the two key goals "market efficiency" and "reliable operation" at odds with each other?
- How can electric power system operations be adequately protected against hackers, insider trading, and other illegal disruptive activities as these operations come to depend more heavily on Internet-enabled communication and automation?

Evolution of the Electric Power Industry with Intelligent Adaptive Agents
Chapter 3 in Market Analysis and Resource Management, edited by A.
Faruqui and K. Eakin, Kluwer Publishers, March 2002.
- Abstract: The author discusses the development of the
Simulator for Electrical Power Industry Agents (SEPIA) sponsored by the
Electric Power Research Institute (EPRI). SEPIA uses autonomous adaptive
agents to represent possible industrial components (e.g., generation units,
transmission system, load) and the corporate entities (e.g., GenCos and
LoadCos) that own these components. Objectives are: (1) to develop a
high-fidelity scenario-free modeling and optimization tool to use for gaining
strategic insight into the operation of the deregulated power industry; (2)
to show how networks of communicating and cooperating intelligent software
agents can be used to adaptively manage complex distributed systems; and (3)
to investigate how collections of agents (agencies) can be used to buy and
sell electricity and participate in the electronic market place and,
ultimately, to create self-optimizing and self-healing capabilities for the
electric power grid and the interconnected critical infrastructures.

"The energy domain is still dominated by equilibrium models that underestimate both the dangers and opportunities related to
climate change. In reality, climate and energy systems contain tipping points, feedback loops, and exponential developments. This paper describes how to create realistic energy transition management models: quantitative models that can discover profitable pathways from fossil fuels to renewable energy. ...
The agent-based approach is found to be uniquely suited for the complex adaptive sociotechnical systems that must be modelled.
But the choice for agent-based models does not mean a rejection of other approaches because they can be accommodated within
the agent-based framework. We conclude with practical guidelines."

IEEE Power and Energy Magazine, 2004, 39-46
"The electric power industry around the world is undergoing an extensive restructuring process. In many countries the traditional vertically integrated power utilities are being unbundled and replaced with a number of separate business entities dealing with the generation, transmission, and distribution of electric power. One of the most significant features of the restructuring process is the introduction of electricity markets, aimed at providing competitive electricity service to consumers. As power markets are relatively new and still continue to evolve, there is a growing need for advanced modeling approaches that simulate the behavior of electricity markets over time and how market participants may act and react to the changing economic, financial, and regulatory environments in which they operate. (This paper argues that a) new and rather promising approach is to model the electricity market as a complex adaptive system using an agent-based modeling and simulation approach."

- Abstract: "Liberalization, climate policy, and promotion of renewable energy are challenges to players of the electricity sector in many countries. Policy makers have to consider issues like market power, bounded rationality of players, and the appearance of fluctuating energy sources in order to provide adequate legislation. Furthermore the interactions between markets and environmental policy instruments become an issue of increasing importance. A promising approach for the scientific analysis of these developments is the field of agent-based simulation. The goal of this article is to provide an overview of the current work applying this methodology to the analysis of electricity markets."

Chapter 13 (pp. 715-766) in Cars Hommes and Blake LeBaron (Eds.), Handbook of Computational Economics 4: Heterogeneous Agent Models, Handbooks in Economics Series, North Holland (Elsevier), Amsterdam, the Netherlands, 2018.
Electric power systems consist of large numbers of heterogeneous participants interacting within an intricate layered network of economic and operational relationships. Decision-making in these systems has been extensively decentralized in many industrialized countries over the past twenty years in an attempt to increase their reliability and efficiency. Given the high negative impact of power disruptions, these decentralization efforts have typically been preceded by extensive sensitivity studies with empirically-based computational models. This chapter discusses the current and potential use of agent-based computational modeling to develop novel transactive energy system (TES) designs for electric power systems. TES designs are decentralized market-based designs that permit electric power systems to operate more fully in accordance with basic economic principles while maintaining overall system reliability and efficiency.

- Abstract: Power systems have distinctive features that greatly complicate the development of auction designs. This study reviews the theory and practice of auction design as it relates specifically to U.S. restructured wholesale power markets, i.e., centrally-administered wholesale power markets with congestion managed by locational marginal prices. Basic auction concepts such as reservation value, net seller surplus, net buyer surplus, competitive market clearing, market efficiency, market pricing rules, supply offers, demand bids, strategic capacity withholding, and market power are explained and illustrated. Complicating factors specific to wholesale power markets are clarified, and recent advances in computational tools designed to address these complications are briefly noted.

- Abstract: This paper applies two experimental economics methods (i.e., agent-based modeling and laboratory experiment) to a market test suite that is based on a fictional European wholesale electricity market. Quantitative results of generators’ strategic behavior in this market context are separated between generators played by human subjects (i.e., master students) in a laboratory experiment and generators represented by computational agents in an agent-based model. The behavior is measured through offers that students or agents make when participating in the electricity trading auction and the market outcomes under both methods are discussed in order to illustrate the difference between the behavior of human and computational agents (and to attempt to explain why the computational agents outperform the human subjects). The paper also identifies the improvements that would need to be made to the market test suite to allow for a more conclusive comparison in future experiments.

- Abstract: "The complexity of electricity markets calls for rich and flexible modeling techniques that help to understand market dynamics and to derive advice for the design of appropriate regulatory frameworks. Agent-Based Computational Economics (ACE) is a fairly young research paradigm that offers methods for realistic electricity market modeling. A growing number of researchers have developed agent-based models for simulating electricity markets. The diversity of approaches makes it difficult to overview the field of ACE electricity research; this literature survey should guide the way through and describe the state-of-the-art of this research area. In a conclusive summary, shortcomings of existing approaches and open issues that should be addressed by ACE electricity researchers are critically discussed."

Proceedings of the IEEE Power Engineering Society General Meeting 2006, Montreal, June 2006 (electronic).
- Abstract: "Power industry restructuring continues
to evolve at multiple levels of system operations. At the bulk electricity level, several organizations charged with regional system operation are implementing versions of a Wholesale Power Market Platform (WPMP) in response to U.S. Federal Energy Regulatory Commission initiatives. Recently the Energy Policy Act of 2005 and several regional initiatives have been pressing the integration of demand response as a resource for system operations. These
policy and regulatory pressures are driving the exploration of new market designs at the wholesale and retail levels. The complex interplay among structural conditions, market protocols, and learning behaviors in relation to short-term and longer-term market performance demand a flexible computational environment where designs can be tested and sensitivities to power system and market rule changes can be explored. This paper discusses the use of agent-based
computational methods for the study of electricity markets at the wholesale and retail levels, and explores distinctions in problem formulation between these levels."

- Abstract: "The restructured electricity market is a complex adaptive system and world-wide experiences show that market design is a complicated task. Recently, under the paradigm of agent-based computational economics (ACE), a new research focus is forming and a large number of literatures are springing up, but there is still no discussion on ACE’s theoretical value and insufficiency in the research of electricity market in a hierarchy of methodologies. Therefore the authors' research is an attempt in this aspect. By means of analyzing the evolution of economics methodology from mathematical deduction to simulation induction, and their inherent relevance, the unique superiority of ACE on the level of methodology is expounded. A further selective survey on existing literatures shows that with the ACE model the marketization process can be understood clearly in deeper level and wider scope. Finally, to give a reference to theoretical progress, the prospective application of ACE, especially its potential in China’s electric sector restructuring,is discussed."

Agents learn using hierarchical learning classifier systems.

Applied Energy, Vol. 275, October, 2020. DOI:10.1016/j.apenergy.2020.115182/
An open source test system is developed that permits the dynamic modeling of centrally-managed wholesale power markets operating over high-voltage transmission grids. In default mode, the test system models basic operations in the Electric Reliability Council of Texas (ERCOT): namely, centrally-managed day-ahead and real-time markets operating over successive days, with congestion handled by locational marginal pricing. These basic operational features characterize all seven U.S. energy regions organized as centrally-managed wholesale power markets. Modeled participants include dispatchable generators, load-serving entities, and non-dispatchable generation such as unfirmed wind and solar power. Users can configure a broad variety of parameters to study basic market and grid features under alternative system conditions. Users can also easily extend the test system's Java/Python software classes to study modified or newly envisioned market and grid features. Finally, the test system is integrated with a high-level simulation framework that permits it to function as a software component within larger systems, such as multiple seamed energy regions or integrated transmission and distribution systems. Detailed test cases with 8-bus and 200-bus transmission grids are reported to illustrate these test system capabilities.

"In the context of the 2009 debate on reforming the Italian market, a realistic agent-based computational model of the day-ahead market session of the Italian wholesale electricity market is simulated to compare market performances between uniform-price and pay-as-bid clearing mechanisms. An empirical validation of computational results at a macro-level is performed to test for accuracy of simulated outcomes with historical ones. The level of prices are accurately reproduced except for few peak hours. As far as concerns pay-as-bid auction, the computational experiments point out that it results in higher market prices than the uniform-price auction. In the pay-as-bid mechanism, sellers’ endeavours to maximize their profits are more costly thus leading to higher price levels."

In this paper, we describe a smart grid technology that integrates demand and supply flexibility in the operation of the electricity system through the use of dynamic pricing. Over the last few years, this technology has been researched and developed into a market-ready system, and has been deployed in a number of successful field trials. Recent field experiences and simulation studies show the potential of the technology for network operations (e.g. congestion management and black-start support), for market operations (e.g. virtual power plant operations), and integration of large-scale wind power generation.

Hongyan Li and Leigh Tesfatsion, "Co-Learning Patterns as Emergent Market Phenomena: An Electricity Market Illustration"
Journal of Economic Behavior and Organization, Vol. 82, Issues 2-3, 2012, 395-419. The published article is available
The definition of emergence remains problematic, particularly for systems with purposeful human interactions. This study explores the practical import of this concept within a specific market context: namely, a double-auction market for wholesale electric power that operates over a transmission grid with spatially located buyers and sellers. Each profit-seeking seller is a learning agent that attempts to adjust its daily supply offers to its best advantage. The sellers are co-learners in the sense that their supply offer adjustments are in response to past market outcomes that reflect the past supply offer choices of all sellers. Attention is focused on the emergence of
co-learning patterns, that is, global market patterns that arise and persist over time as a result of seller co-learning. Examples of co-learning patterns include correlated seller supply offer behaviors and correlated seller net earnings outcomes. Heat maps are used to display and interpret co-learning pattern findings. One key finding is that co-learning strongly matters in this auction market environment. Sellers that behave as Gode-Sunder budget-constrained zero-intelligence agents, randomly selecting their supply offers subject only to a break-even constraint, tend to realize substantially lower net earnings than sellers that tacitly co-learn to correlate their supply offers for market power advantages.

IEEE Transactions on Power Systems, Vol. 26, Issue 2, 2011, 627-641.
This study uses 5-bus and 30-bus test cases to explore
ISO net surplus (congestion rent) collections and allocations
in wholesale power markets with grid congestion managed by
locational marginal prices (LMPs). Price-sensitivity of demand
and generator learning capabilities are taken as experimental
treatment factors. A key finding is that conditions resulting in
greater generator capacity withholding, hence higher and more
volatile LMPs, also result in greater ISO net surplus collections
that can be substantial in size. A key conclusion is that ISO net
surplus collections should be used pro-actively to mitigate the
conditions encouraging generator capacity withholding and hence
high and volatile LMPs rather than to provide ex post support
for LMP payment offsets and LMP volatility risk hedging as is
currently the norm.

Agent-based computational economics (ACE) modeling tools are capable of handling this degree of complexity. In concrete support of this claim, this study presents an ACE test bed designed to permit the exploratory study of restructured U.S. wholesale power markets with transmission grid congestion managed by locational marginal prices (LMPs). Illustrative findings are presented showing how spatial LMP
cross-correlation patterns vary systematically in response to changes in the price responsiveness of wholesale power demand when wholesale power sellers have learning capabilities. These findings highlight several distinctive features of ACE modeling: namely, an emphasis on process rather than on equilibrium; an ability to capture complicated structural, institutional, and behavioural real-world aspects (miccro-validation); and an ability to study the effects of changes in these aspects on spatial and temporal outcome distributions."

This study uses the AMES Wholesale Power Market Test Bed to investigate separation and volatility of locational marginal prices (LMPs) in an ISO-managed restructured wholesale power market operating over an AC transmission grid. Particular attention is focused on the dynamic and cross-sectional response of LMPs to systematic changes in demand-bid price sensitivities and supply-offer price cap levels under varied learning specifications for the generation companies. Also explored is the extent to which the supply offers of the marginal (price-determining) generation companies induce correlations among neighboring LMPs.

This study extends the agent-based 8-Zone ISO-NE
Test System to include wind turbine agents, each characterized
by location, physical type, and an output curve mapping local
wind speed into wind power output. Increases in wind power
penetration (WPP) are modeled as build-outs of investment
queues for planned wind turbine installations. The extended
system is used to study the effects of increasing WPP under
both stochastic and deterministic day-ahead market (DAM)
formulations for security-constrained unit commitment (SCUC).
For each tested WPP, the expected cost saving resulting from a
switch from deterministic to stochastic DAM SCUC is found
to display a U-shaped variation as the reserve requirement
(RR) for deterministic DAM SCUC is successively increased.
Moreover, the RR level resulting in the lowest expected cost
saving systematically increases with increases in WPP.

presented at the North American Association for Computational and Social Organization (NAACSOS) Conference, Notre Dame, Indiana, June 26-28, 2005.
- Abstract: EMCAS (Electricity Market Complex Adaptive Systems) is an agent-based simulation model of the electric power market designed to investigate market restructuring and deregulation and to understand the implications of a competitive power market on electricity prices, availability, and reliability. Model validation is an essential part of the model development process if models are to be accepted and used to support decision making. This paper describes the validation process for the EMCAS model and its results for use in practical decision making. The validation process also is an initial attempt to establish a general and practical framework for agent-based model validation.

- Abstract: This paper develops a nonzero sum stochastic game theoretic model and a reinforcement learning (RL)-based solution framework that allow assessment of market power in double-auction (DA) electricity markets. Since there are no available methods to obtain exact analytical solutions of stochastic games, an RL-based approach is utilized, which offers a computationally viable tool to obtain approximate solutions. These solutions provide effective bidding strategies for the DA market participants. The market powers associated with the bidding strategies are calculated using well-known indexes
like Herfindahl–Hirschmann index and Lerner index and two
new indices, quantity modulated price index (QMPI) and revenue-
based market power index (RMPI), which are developed in

- Abstract: This study reports experimental market power and efficiency outcomes for a computational wholesale electricity market operating in the short run under systematically varied concentration and capacity conditions. The pricing of electricity is determined by means of a clearinghouse double auction with discriminatory midpoint pricing. Buyers and sellers use a modifed Roth-Erev individual reinforcement learning algorithm to determine their price and quantity offers in each auction round. It is shown that high market efficiency is generally attained, and that market microstructure is strongly predictive for the relative market power of
buyers and sellers independently of the values set for the reinforcement learning parameters. Results are briefly compared against results from an earlier electricity study in which buyers and sellers instead engage in social mimicry learning via genetic algorithms.

"The objective of this paper is to test whether or not software agents can match the observed behavior of human subjects in laboratory tests of markets. For this purpose, one set of tests uses four software agents and two human subjects to represent six suppliers in three different market situations: no forward contracts; fixed price forward contracts; and renewable forward contracts. An identical set of tests is conducted using software agents to represent all suppliers. The results show that software agents were able to replicate the behavior of human subjects effectively in the experiments, and have the potential to be used effectively in testing electricity auctions, doing additional sensitivity tests, and supplementing results obtained using human subjects."

- Abstract: This paper develops an agent-based
computational model to investigate the bidding behavior of generating
companies in a short-term bilateral market. Each generating company is
modelled with specific strategic and operational objectives and bounded
reasoning abilities based on principles of reinforcement learning. Price and market power effects are explored under a number of different treatments (e.g., settlement procedures, demand conditions, number of generators).

Energy Policy, Volume 38, 2010, 1588-1595.
Choosing a desired policy for divestiture of dominant firms’ generation assets has been a challenging task and open question for regulatory authority. To deal with this problem, in this paper, an analytical method and agent-based computational economics (ACE) approach are used for ex-ante analysis of divestiture policy in reducing market power.

This study develops a fuzzy Q-learning (FQL) method to model
a power supplier’s strategic bidding behavior in a computational
electricity market. In the simulation framework, the power supplier uses FQL to select its bidding strategy conditional on the supplier's past experiences, risk preferences, and QL learning parameters that are adaptively changing to reflect the supplier's current market power opportunities. The application of the proposed FQL methodology for a power supplier in a multi-area power system shows the performance improvement in comparison to QL with fixed parameters.

IEEE Computational Intelligence Magazine, 3(4), November 2008, 56-72.
- Abstract: Wholesale power markets operating over transmission grids subject to congestion have distinctive features that complicate the detection of market power and operational inefficiency. This study uses a wholesale power market test bed with strategically learning traders to experimentally test the extent to which market performance measures commonly used for other industries are informative for the dynamic operation of restructured wholesale power markets. Examined measures include the Herfindahl-Hirschman Index (HHI), the Lerner Index, the Residual Supply Index, the Relative Market Advantage Index, and the Operational Efficiency Index. It is also shown that the objective function commonly used to manage these markets deviates systematically from the standard economic measure of market efficiency when grid congestion is present.

Computational Economics, 30(3), 2007, 291-327. This article is an abridged version of ISU Economics Working Paper No. 06025
- Abstract: In April 2003 the U.S. Federal Energy Regulatory Commission proposed a complicated market design - the Wholesale Power Market Platform (WPMP) -- for common adoption by all U.S. wholesale power markets. Versions of the WPMP have been implemented in New England, New York, the mid-Atlantic states, the Midwest, the Southwest, and California. Strong opposition to the WPMP persists among some industry stakeholders, however, due largely to a perceived lack of adequate performance testing. This study reports on the model development and open-source implementation (in Java) of a computational wholesale power market organized in accordance with core WPMP features and operating over a realistically rendered transmission grid subject to congestion effects. The traders within this market model are strategic profit-seeking agents whose learning behaviors are based on data from human-subject experiments. Our key experimental focus is the complex interplay among structural conditions, market protocols, and learning behaviors in relation to short-term and longer-term market performance. Findings for a dynamic 5-node transmission grid test case are presented for concrete illustration. It is shown for this example that generators easily learn to implicitly collude on higher-than-true marginal costs when the demand bids of load-serving entities take the form of fixed loads.

This study investigates the effects of dynamic-price retail contracting on integrated retail and wholesale (IRW) power market operations. Performance is evaluated by means of carefully defined metrics for system stability and market participant welfare. The study is carried out for an IRW Test Case for which 500 households have price-responsive air-conditioning systems. It is shown that dynamic-price retail contracting can give rise to braided cobweb dynamics consisting of two interwoven cycles for power and price levels exhibiting either stability or instability depending on system conditions. Moreover, even in stable cases, dynamic-price retail contracts generally result in worse welfare outcomes for households than flat-rate retail contracts.

International Journal of Management Science and Engineering Management, 1(2), 2006, 83-97.
- Abstract: This paper studies the dynamics in two-settlement electricity markets. In these markets, energy producers sign strategic forward contracts in the forward market, and engage in spatial oligopolistic competition
in the spot market. We develop an agent-based model for simulating the outcomes of such markets.
Numerical simulations imply that the access to the forward market leads to more competitive behaviors of the
suppliers in the spot market, and thus to lower spot energy prices.

"The Impact of Carbon Pricing on Wholesale Electricity Prices, Carbon Pass-Through Rates and Retail Electricity Tariffs in Australia"
Working Paper, Department of Economics, University of Queensland, April 2012.
- Abstract: "The purpose of this article is to investigate the impact that the introduction of a carbon price signal will have on wholesale electricity prices, carbon-pass-through rates and retail electricity rates in the states making up the Australian National Electricity Market (NEM). In order to assess this, we employ an agent based model of the NEM called the ANEM model which contains many of the salient features of the NEM: intra-state and inter-state transmission branches, regional location of generators and load centres and accommodation of unit commitment features. A DC OPF algorithm is used to determine optimal dispatch of generation plant and wholesale prices within the ANEM model. We utilise ANEM model scenario runs to examine the impact of carbon prices on wholesale prices and carbon passthrough rates. This information is then used to assess the impact on retail electricity tariff rates and shares of cost components making up residential retail tariff rate structures for different states in the NEM."
David Young, Stephen Poletti, Oliver Browne, "Can Agent-Based Models Forecast Spot Prices in Electricity markets?: Evidence from the New Zealand Electricity Market"
Working Paper, Electric Power Research Institute (EPRI), Palo Alto, CA, January 2012.
- Abstract: "Modelling price formation in electricity markets is a notoriously difficult process, due to physical constraints on electricity generation and flow. This difficulty has inspired the recent development of bottom-up agent-based models of electricity markets. While these have proven quite successful in small models, few authors have attempted any validation of their model against real-world data in a more realistic model. In this paper, we take one of the most promising algorithms, the modified Roth and Erev algorithm, and apply it to a 19-node simplification of the New Zealand electricity market. Once key variables such as water storage are accounted for, we show that our model can mimic short-run (weekly) electricity prices at these 19 key nodes quite closely."

"Evaluating Government's Policies on Promoting Smart
Metering Diffusion in Retail Electricity Markets via
Journal of Production Innovation Management, 28, 2011, 169-186.
"In this paper, we develop an agent-based model of a market game in order to evaluate the effectiveness of the U.K.
government's 2008-2010 policy on promoting smart metering in the U.K. retail electricity market. We break down the
policy into four possible policy options. With the model, we study the impact of the four policy options on the dynamics
of smart metering diffusion and suggest policy implications. The context of the paper is a practical application of agent-based
simulation to the retail electricity market in the United Kingdom. The contributions of the paper are both in the
areas of policymaking for the promotion of innovation diffusion in the electricity market and in methodological use of
agent-based simulation for studying the impact of policies on the dynamics of innovation diffusion."

- Developed by Vlasios Voudouris, ACEGES is a decision-support tool for energy policy by means of controlled computational experiments. The ACEGES tool is designed to be the foundation for large custom-purpose simulations of the global energy system. The ACEGES tool is written in Java and runs on Windows, Mac OS, and Linux platforms. It is based on a discrete-event multiagent simulation library (MASON), an evolutionary computation toolkit (ECJ), the R project for statistical computing, the GAMLSS framework for statistical modeling of agent behavioral rules, and (in certain specific cases) the Mathematica kernel.
AMES: Agent-Based Modeling of Electricity Systems
(Java/Python, Open Source)
The AMES Wholesale Power Market Test Bed, developed entirely in Java by an interdisciplinary team of researchers at Iowa State University, is a modular and extensible agent-based computational laboratory for studying the dynamic efficiency and reliability of wholesale power markets restructured in accordance with guidelines issued by the U.S. Federal Energy Regulatory Commission.
AMES is an acronym for Agent-based Modeling of Electricity Systems.
AMES models traders with learning capabilities interacting over time in an ISO-managed wholesale power market operating over a transmission grid subject to congestion effects. Congestion on the grid is managed by means of locational marginal prices derived from bid/offer-based optimal power flow solutions.
- AMES is a free open-source tool suitable for research, teaching, and training applications. It is designed for the intensive experimental study of small to medium-sized systems
(2-500 nodes). A graphical user interface permits the creation, modification, analysis and storage of scenarios,
parameter initialization and editing, specification of behavioral rules (e.g. learning methods) for market participants, and output reports through table and chart displays.
(Java/Python, Open Source, GitHub Repository)
AMES V5.0 is an open source software platform capturing salient features of U.S. RTO/ISO-managed wholesale power markets operating over high-voltage transmission grids during successive days, with grid congestion handled by Locational Marginal Pricing (LMP).
AMES V5.0 was developed by Swathi Battula and Leigh Tesfatsion at Iowa State University, with support from researchers at the Pacific Northwest National Laboratory (Tom McDermott, Mitch Pelton, Qiuhua Huang, and Sarmad Hanif).
AMES V5.0 consolidates features from
previous AMES versions
and continues the main developments in these previous versions.
AMES V5.0 supports the submission of supply offers and demand bids (in both fixed and price-sensitive form) into daily DAM SCUC/SCED and RTM SCED optimizations formulated as Mixed Integer Linear Programming (MILP) problems with a comprehensive set of system constraints. It permits continual updating of initial state conditions to permit market operations to run over successive days. The package includes an 8-bus test case based on data, operations, and market timing for the Electric Reliability Council of Texas (ERCOT) energy region.
In addition, AMES V5.0 is integrated with a high-level simulation framework that permits it to function as a software component within larger systems, such as multiple seamed energy regions or integrated transmission and distribution systems.
Eight-Zone ISO-NE Test System
(Java/Python, Open Source, BitBucket Repository)
- A team of researchers at Iowa State University has developed an open source 8-Zone ISO-NE Test System based on structural attributes and data from the ISO New England (ISO-NE). A detailed description of this test system, together with an illustrative test case and a pointer to a code/data repository site, can be found in the following article:

EMCAS: Electricity Market Complex
Adaptive System (RePastJ, Commercial)
- The Center for Energy, Environmental, and Economic Systems Analysis (CEEESA) at Argonne National Laboratory has developed the EMCAS (Electricity Market Complex Adaptive System) platform as commercially available software. Diverse decision-making participants in a wholesale electricity market are represented as "agents." Each agent has its own objectives, decision-making rules, and behavioral patterns. Moreover, each agent can draw on an array of historical information (e.g., past power prices) and projected data (e.g., next-day load) to support its own unique decision-making process. EMCAS
is implemented by means of the Recursive Porus Agent Simulation Toolkit in Java (RePastJ), a Java-based class library designed to facilitate agent-based simulations.
ERCOT Test System
(Java/Python, Open Source, GitHub Repository)
- The ERCOT Test System is an open source test system developed by Iowa State University (ISU) and Pacific Northwest National Laboratory (PNNL) researchers. The test system permits the dynamic modeling of centrally-managed wholesale power markets operating over high-voltage transmission grids.
In default mode, the test system models basic operations in the Electric Reliability Council of Texas (ERCOT): namely, centrally-managed day-ahead and real-time markets operating over successive days, with congestion handled by locational marginal pricing. These basic operational features characterize all seven U.S. energy regions organized as centrally-managed wholesale power markets. Modeled participants include dispatchable generators, load-serving entities, and non-dispatchable generation such as unfirmed wind and solar power. Users can configure a broad variety of parameters to study basic market and grid features under alternative system conditions.
Users can also easily extend the test system's Java/Python software classes to study modified or newly envisioned market and grid features. Finally, the test system is integrated with a high-level simulation framework that permits it to function as a software component within larger systems, such as multi-country systems or integrated transmission and distribution systems.
Detailed descriptions of this test system together with illustrative 8-bus and 200-bus test cases are provided in the following article, along with a pointer to the GitHub code/data repository site:

ITD TES Platform V2
is a co-simulated platform developed by Swathi Battula and Leigh Tesfatsion at Iowa State University, with support from Pacific Northwest National Laboratory (PNNL) and the U.S. Department of Energy (DOE). It permits the modeling and implementation of an Integrated Transmission and Distribution (ITD) system operating over successive days. It has specifically been developed to facilitate performance testing of bid-based Transactive Energy System
(TES) designs proposed for implementation within ITD systems.
- Zita Vale and her collaborators at the Polytechnic Institute of Porto, Portugal, have developed MASCEM,
a multi-agent platform for the simulation of
competitive electricity markets.
Abstract from above site: "The MASCEM multiagent model includes players with strategies for bid definition, acting in forward, day-ahead, and balancing markets and considering both simple and complex bids. Our goal with MASCEM was to simulate as many market models and player types as possible. This approach makes MASCEM both a short and medium term simulation as well as a tool to support long-term decisions, such as those taken by regulators. This article proposes a new methodology integrated in MASCEM for bid definition in electricity markets. This methodology uses reinforcement learning algorithms to let players perceive changes in the environment, thus helping them react to the dynamic environment and adapt their bids accordingly."
MATREM: An Agent-Based Simulation Tool
for Electricity Markets (JADE/Jadex)
MATREM (Multi-Agent TRading in Electricity Markets) is an agent-based system that permits users to analyze the behavior and outcomes of electricity markets. MATREM supports a day-ahead market, an intra-day market, and a real-time market. The pricing mechanism is founded on marginal pricing theory; both system marginal pricing and locational marginal pricing are supported. MATREM also supports a bilateral marketplace for negotiating the details of long-term bilateral contracts.
