Primary Purpose The Dispatch and Investment Evaluation Tool with Endogenous Renewables (DIETER) has initially 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. Meanwhile, several model extensions have been developed and applied to different research questions. 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 energy storage and other flexibility options related to arbitrage, firm capacity, and reserves.
Primary Outputs Capacities, dispatch (and prices)

further properties DIETER also includes reserve markets and stylized representations of solar prosumage, V2G, and various types of residential power-to-heat. Further power-to-x (hydrogen) details are currently being developed.

User behaviour and demand side management DSM: Detailed representation of load shifting and load curtailment; "User behaviour": If this means empirically-founded behavioural aspects, the answer is no.
Changes in efficiency Exogenous parameter assumptions
Market models fundamental model
Geographical coverage In most applications so far; focus on Germany; which is treated as one node; extended version with additional central European country nodes is available

If you find bugs or if you have ideas to improve the Open Energy Platform, you are welcome to add your comments to the existing issues on GitHub.
You can also fork the project and get involved.

Please note that the platform is still under construction and therefore the design of this page is still highly volatile!
