Abstract

Abstract: With construction of active distribution network, load control has become a general means for power system dispatch. Based on load control flexibility, a service restoration strategy for distribution system with distributed generation(DG) is proposed, which fully considers the influence of load control. When serious failures result in large area power blackout, it is difficult to ensure that DG switches to islanding operation mode without losing stability as a result of long operation time, given numerous manual switches in current distribution system. In order to maintain power supply of important load and make full use of renewable energy sources, proposed method switch DG to islanding operation mode first using load control with adaptively selecting mathematical model. Second, for the purpose of reducing active loss and number of switching operations, the NSGA2 algorithm is adopted to perform reconfiguration of distribution network to restore non-failure power blackout area using a loop encoding strategy. The proposed restoration method is exerted on a 33-node feeder. The simulation results demonstrate validity of proposed method.
