基于改进粒子群优化算法的微电网电流保护整定方法
MPSO based protective relay coordination for micro-grid
摘要
Abstract
A method of the relay settings of overcurrent protection for micro-grid using MPSO ( modified particle swarm optimiza-tion) algorithm is proposed in this paper.When selecting the micro-grid current protection setting values, the operating time which is the key problem among all relays is minimized. The protection coordination problem is solved by improving the initialization and weight of PSO algorithm and choosing pickup current suitable, the premature convergence problem is also avoided. The optimal settings of the relays are solved by using the PSO algorithm. The results solved by using the MPSO algorithm are close to optimal solutions, and the validity of the proposed method are shown in this paper.关键词
