Kriegers Flak Combined Grid Solution - novel double use of offshore equipment

摘要

The Krieger Flak Combined Grid Solution (KF CGS) will be in commercial operation from early 2019. Major novelty of the project is the combination of the existing and scheduled offshore wind power grid-connection systems with an interconnector between the two countries. Germany and Denmark. The project shall use equipment for offshore wind power transmission for the interconnector in order to utilize the remaining transmission capacity for the electricity market when it is not fully utilized by infeed from wind energy. KF CGS comprises platforms of three wind farms (Danish Kriegers Flak and German Baltic 1 & Baltic 2, totalling 966 MW production capacity), the respecting cable connections towards shore as well as a connection between the offshore platforms of Baltic 2 and Kriegers Flak wind farm and an HVDC Back-to-Back (HVDC BtB) converter on the German shore. The HVDC BtB is needed to establish asynchronous interconnection between the two synchronous areas Continental Europe (Germany) and Nordic (Denmark East).
