- In recent years, the installed generation capacity of RES has been increasing rapidly in many regions in Germany. Especially the distribution networks including the low- and medium-voltage level and the high voltage subtransmission networks have to cope with great changes in their network usage. Historically, these networks have been designed to distribute the electric energy generated in large generation units connected to the transmission system to the loads connected to the distribution network. Therefore, the network planning process used a network planning case (NPC) describing the critical load conditions to dimension the network. With the increasing generation capacity installed in these networks, the critical situations can nowadays be caused by a high RES feed-in. In order to host the newly installed generation capacity, a lot of networks need to be expanded. In order to do so, additional NPCs representing these critical feed-in situations are included in the planning process. In the conventional planning process, the identified congestions in the network are resolved by adding new or reinforcing existing assets such as overhead lines, cables or transformers
