The progress of the energy transition and the associated increase in feed-in from renewable generation plants as well as the coal phase-out also create a need for further development in the area of grid reconstruction after a large-scale supply interruption. In grid reconstruction, as in many other areas, cooperation between transmission and distribution system operators is becoming more important and must be further intensified.
E-Bridge, together with Fraunhofer IEE, TU Kaiserslautern and DUtrain, supports the research project of the four German transmission system operators (TSOs) to further develop the grid reconstruction plans.
As part of the project, the 2nd FNN Expert Day took place on July 29, 2021. In the 2nd FNN Expert Day, the TSOs and project partners presented the methods and concretized requirements developed so far in the project and discussed them with the stakeholders. The main focus of the work of the last months was on the development of methods, among others, for the determination of the demand of black start capable plants, solution approaches for black start resistant and black start robust communication as well as the necessary support systems for the increasing complexity of the grid reconstruction. The methods and approaches developed will be used to adapt grid reconstruction plans in the future.
