Research on Distribution Network Reconfiguration Based on Chicken Swarm and Particle Swarm Optimization Hybrid Algorithm

为使配电网接入分布式电源后能快速、准确地重构,针对配电网重构的算法进行改进。对于粒子群算法易陷入局部最优的问题,提出与鸡群算法进行融合,以扩大搜索范围,避免搜索过程陷入局部极小,从而得到质量更好的解。最后在IEEE 33节点系统中,考虑分布式电源的接入,运用鸡群粒子群算法进行算例验证。

In order to make the distribution network can be reconfigured quickly and accurately after it is connected to the distributed power source,the algorithm of distribution network reconfiguration is improved.For the problem that particle swarm optimization algorithm is easy to fall into local optimization,it is proposed to merge with chicken swarm algorithm to expand the search range and avoid the search process from falling into local minimum,so as to obtain better quality solutions.Finally,in the IEEE 33 node system,considering the access of distributed power,the chicken swarm and particle swarm hybird optimization algorithm is used to verify the results.
