The Dispatch and Investment Evaluation Tool with Endogenous Renewables (DIETER) has been developed in the research project StoRES to study the role of power storage and other flexibility options in a greenfield setting with high shares of renewables. The model determines cost-minimizing combinations of power generation, demand-side management, and storage capacities as well as their respective dispatch in both the wholesale and the reserve markets. DIETER thus captures multiple system values of power storage related to arbitrage, firm capacity, and reserves. DIETER is an open source model which may be freely shared alike and adapted for non-commercial uses. It is licensed under the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License. The model is implemented in the General Algebraic Modeling System (GAMS). Running the model thus also requires a GAMS system, an LP solver, and respective licenses.
Based on GAMS; CPLEX. Using MS Excel for data processing.
