摘要
微网系统中保护装置的安装位置对供电可靠性具有重要影响。本文介绍粒子群优化方法的基本原理,用3项可靠性指标构成多目标函数,并考虑多种DG运行模式和微网故障隔离模式,构建了基于粒子群算法的微网保护装置位置优化模型,并给出了算法的具体应用步骤。通过在改造的RBTS算例中的应用,验证了该方法的有效性,并分析了保护安装数量和位置对微网可靠性的影响。
The placement of protective devices in microgrid system has an important influence on power supply reliability.Firstly,the basic principles of particle swarm optimization,and the multi-objective function of which optimization was constructed by three reliability indexes. Considering varieties of DG operating modes and microgrid fault isolation modes,the microgrid protective devices optimization models based on PSO was established,whose application method was further given step by step. At last,by the application in RBTS example,the method effectiveness was verified and the effects of quantity and placement of protective devices on microgrid reliability were analyzed.
