Operational planning of DER considering novel congestion management markets

The increase of distributed energy resources (DER) within the electric distribution grids poses challenges for grid operators as well as the operators of DER units. To resolve potential operational grid congestions, currently discussed congestion management (CM) markets could extend the grid operators toolbox and could unlock the small-scale flexibility potentials of DER. As DER are often marketed by commercial aggregators due to potential risks and market barriers, CM markets offer additional marketing opportunities that need to be considered within the operational planning. In the following, a planning approach for aggregators is presented and applied using an example of a wind power plant as well as an energy storage. Thereby, uncertainties such as volume- and price risks as well as the probability of acceptance and activation within the CM markets are considered based on stochastic programming.
