DIETERpy: A Python framework for the Dispatch and Investment Evaluation Tool with Endogenous Renewables

DIETER is an open-source power sector model designed to analyze future settings with very high shares of variable renewable energy sources. It minimizes overall system costs, including fixed and costs various generation, flexibility coupling options. Here we introduce DIETERpy that builds on the existing version, written in General Algebraic Modeling System (GAMS), enhances it a Python framework. This combines regarding pre- post-processing data straightforward algebraic formulation GAMS use efficient solvers. also offers browser-based graphical user interface. The new framework be easily accessible as enables users run model, alter its configuration, define numerous scenarios without deeper knowledge GAMS. Code, data, manuals are available public repositories under permissive licenses for transparency reproducibility.
