摘要：
The elements of branch array are effectively combined to form the power restoration scheme and the relative load fitness and risk degree are applied as index to guide its optimization procedure. For the full use of the post-fault remaining power capacity, the controlled loads are reasonably switched to guarantee the power supply for the critical loads while restore the de-energized loads as more as possible. Power-supply island partitioning is carried out for the healthy area to divide the tie-lines between feeders and the DGs (Distributed Generations) for realizing the coordinated restoration. Aiming at the independency of DGs and spare tie-lines during the preliminary island partitioning and their relevancy during the optimization process, a multi agent system including information layer, execution layer, equipment layer and coordination layer is adopted for the parallel computation and coordinated optimization. The feasibility and effectiveness of the proposed method are verified by the simulation for 69-bus test system. © 2016, Electric Power Automation Equipment Press. All right reserved.
