Service restoration of distribution system with Distributed Generation

The large scale penetration of Distributed Generation (DG) within distribution networks will significantly impact on the operation of future distribution systems. It will also be possible to take advantage of DG with regard to the service restoration in distribution networks. For example, when there is not enough capacity to restore the entire out-of-service area, the network operator can implement intentional island operation with the support of black-start DG. Furthermore, from the viewpoint of making full use of renewable energy sources, the network operator is required to ensure the interconnection of the renewable units that are installed in the out-of-service area as many as possible. Based on these assumptions, this paper establishes a new optimization model for the solution of the service restoration problem that incorporates DG and applies NSGA-II to solve the model. Numerical analysis verifies the feasibility and correctness of the model.
