(German Energy System Optimization) Modell


Sebastian Rauner

The intermittent nature of the renewable energy sources in contrast to the relatively constant production characteristics of conventional power plants require a very detailed modelling to be able to investigate the interplay of these two technology groups.

The GESOp model is a tool designed to understand these challenges of an ever increasing complexity which comes with the shift of the political focus away from conventional to renewable based energy sources in Germany. The focus lies on the detailed modelling of the spot market for electricity and the operation of the conventional power plants covering the residual load. The power plant constraints include, among others, ramping, minimal up and down time and part load efficiency. Although it is an economic dispatch model it is capable of investigating long time horizons while keeping a detailed modelling of the operation of the single power plants. In combination with the inclusion of the import and export with neighbouring countries and a simplified heat market it is possible to investigate a wide range of research questions. Among them, the effect of political instruments and socio-economic developments on the operation pattern of single power plants and the development of the spot market electricity price.
To tackle the future research questions current developments reach from the inclusion of environmental aspects to spatial explicit modelling.
