Power network planning for high penetration of dispersed energy resources. Optimal multi-criteria planning method

The conditions for power network planning in Germany have changed due to the liberalization of the energy market and the legal promotion of dispersed energy resources (DER). To meet these new requirements, an effective multi-criteria optimization method based on game theory has been developed, describing the technical-economical dependencies and the limitations caused by competition. Planning criteria such as economical, technical and operational conditions as well as reliability are considered with respect to their interaction with the energy market. To use this method, dynamic calculations concerning the behavior of DER are necessary for finding the optimal network structure. Suitable models for these simulations recently have been developed and are used during the optimization process. With this combination of the new planning method and DER-models an effective planning tool has been developed for the changed planning environment. A planning example is given to demonstrate the process and its results.
