摘要
鉴于传统的配电网供电恢复算法都没考虑分布式发电孤岛运行产生的影响,提出考虑DG孤岛运行方式下的智能配电网供电恢复算法。当配电网发生严重故障引起大面积停电时,对DG进行孤岛划分,DG按孤岛划分方案转入孤岛运行模式维持对孤岛内重要负荷供电。采用基于二进制粒子群优化算法的供电恢复算法对孤岛外非故障停电区域进行供电恢复,在维持孤岛内重要负荷供电的前提下最大限度地对孤岛外停电区域恢复供电。最后将该算法应用到33节点测试系统,仿真结果验证了该算法的有效性。
In view of the conventional distribution system service restoration methods ignoring the influence of the distributed generation (DG) islanding, a smart distribution system service restoration method using DG islanding technique is proposed. First, when serious failures result in large area power blackout, DG switches to the islanding operation mode using islanding algorithm to maintain the power supply for the important load. Second, a service restoration method based on the binary particle swarm optimization is proposed to restore non-failure power blackout area outside the islanding. On the premise of maintaining the important loads in the islanding, this method restores the loads outside the islanding to the maximal degree. At last, the service restoration method is exerted on 33-node feeder, and the simulation results demonstrate the validity of the method.
