Service Restoration of Distribution Network with DG Based on Dual-population CSO Algorithm

To guarantee both the speediness and global optimization of service restoration of distribution network simultaneously, a hierarchical response fault recovery method based on reconfiguration is proposed, and the crisscross optimization(CSO) algorithm with dual dual-population is applied to seek the reconstruction scheme. Firstly, partial reconstruction using heuristic rules for non-islanding operation is implemented for fast restoration of distribution network connectivity with fewer switching times. Secondly, the optimal solution is searched in the feasible region by CSO algorithm with dual dual-population for global reconstruction while the safety indicators are over-limit, and if the safety indicators are still over-limit, part of non-critical load is shed in the order of the importance index of the load until the disribution network is back to a new safe operation state. Finally, the feasibility and effectiveness of the proposed method are verified by simulation results of improved PG&E distribution system.
