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 variable costs of various generation, flexibility and sector coupling options. Here we introduce DIETERpy that builds on the existing model version, written in the General Algebraic Modeling System (GAMS), and enhances it with a Python framework. This combines the flexibility of Python regarding preand post-processing of data with a straightforward algebraic formulation in GAMS and the use of efficient solvers. DIETERpy also offers a browser-based graphical user interface. The new framework is designed to be easily accessible as it enables users to run the model, alter its configuration, and define numerous scenarios without a deeper knowledge of GAMS. Code, data, and manuals are available in public repositories under permissive licenses for transparency and reproducibility. (C) 2021 The Authors. Published by Elsevier B.V.

Automated summary

DIETERpy is a new framework built on the existing DIETER model, combining the flexibility of Python with the algebraic formulation in GAMS. It offers a user-friendly graphical interface and simplifies model operation for users without deep knowledge of GAMS, while ensuring transparency and reproducibility of data and code.
