Open-Source Software Releases

• AMES Market Package (Open Source, Java/Python, Homepage): AMES (Agent-based Modeling of Electricity Systems) is an agent-based computational platform that permits the dynamic study of a U.S. RTO/ISO-managed wholesale power market operating over a high-voltage transmission grid during successive days, with grid congestion handled by Locational Marginal Pricing (LMP). The latest released version is AMES V5.0 (GitHub Code/Data Repository)

• DCOPFJ (Open Source, Java, Homepage): A free open-source solver for bid/offer-based DC Optimal Power Flow (DCOPF) problems expressed as strictly convex quadratic programming problems.

• Eight-Zone ISO-NE Test System (Open Source, Java/Python, BitBucket Code/Data Repository): The 8-Zone ISO-NE Test System, implemented in part by AMES V4.0, is a software platform based on ISO New England (ISO-NE) data and characteristics. It permits the dynamic study of an ISO-managed wholesale power market operating over an 8-zone transmission grid during successive days, with grid congestion handled by Locational Marginal Pricing (LMP).

• ERCOT Test System (Open Source, Java/Python, GitHub Code/Data Repository): The ERCOT Test System is a software platform that permits the dynamic study of the ERCOT (Texas) ISO-managed wholesale power market operating over a high-voltage transmission grid during successive days, with grid congestion handled by Locational Marginal Pricing (LMP). The ERCOT Test System is implemented in part by AMES V5.0.

• FLS (Open Source, Fortran, Homepage): Flexible Least Squares is a multicriteria optimization method for model specification that does not require the imposition of problematic distribution assumptions on specification errors. The FLS program is an implementation of the FLS method for time-varying linear regression.

• GFLS (Open Source, Fortran, Homepage): Generalized Flexible Least Squares is an implementation of FLS for approximately linear systems.

• ITD Project/Household Formulation (Open Source, Python, GitHub Code/Data Repository): Python code/data for a household electrically connected to a distribution grid within an Integrated Transmission and Distribution (ITD) system. The household is able to participate in a bid-based Transactive Energy System (TES) design implemented within the ITD system.

• ITD TES Platform V2 (Open Source, Java/Python/C++/C, GitHub Code/Data Repository): This co-simulation platform 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 proposed bid-based Transactive Energy System (TES) designs implemented within ITD systems.

• MAM (Open Source, Fortran, Homepage): The Multicriteria Associative Memory solver is a nonlinear estimation method based on a multicriteria associative memory process.

• NASA (Open Source, Fortran, Homepage): The Nonlocal Automated Sensitivity Analysis solver permits the automated tracking of solutions for parameterized nonlinear systems along user-specified parameter paths.

• The DMGame (Open Source, C++, GitHub Code/Data Repository): The Dynamic Macroeconomic Game is an agent-based computational platform that implements the model developed in Sinitskaya and Tesfatsion (JEDC, 2015) for the study of dynamic macroeconomic systems as locally-constructive sequential games. Consumer and firm learning methods can range from simple reactive reinforcement learning to sophisticated anticipatory learning for the approximate achievement of intertemporal objectives.

• TNGLab (Open Source, C++/VB, Homepage): The Trade Network Game Laboratory is an agent-based computational platform that permits the run-time visualization and quantitative study of dynamic network formation and behavioral game interactions among market buyers, sellers, and dealers. Each trader preferentially chooses and refuses its trading partners on the basis of past trading experiences.

• WACCShed (Open Source, Java, Bitbucket Code/Data Repository): The Water And Climate Change Watershed platform is an agent-based computational platform that permits the study of water and climate change issues for watersheds modeled as coupled natural and human systems encompassing both rural and urban land areas.
