Modeling Demand Side Management in European Resource Adequacy Assessments

In the context of the energy transition, a decrease in dispatchable generation capacity from conventional power plants with an increasing integration of volatile, supply-dependent generation plants based on renewable energies is to be expected. Therefore, the question arises whether resource adequacy (RA) is still guaranteed in the European power system. In the future, demand side management (DSM) will play a more important role in ensuring RA. In order to consider DSM processes in the evaluation of RA, a variety of DSM properties must be taken into account. In this paper, four different models with varying levels of detail in considering DSM properties are developed within a cost minimizing dispatch optimization model. Subsequently, the different models are applied to an exemplary scenario and evaluated in terms of DSM usage, influence on the relevant indicators for RA as well as computational runtime. The results demonstrate that the reduction of the level of detail when considering DSM properties is accompanied by an increase in the assumed flexibility of the DSM processes, but also by a significant reduction in the computation runtime.
