Abstract

A fast and effective service restoration algorithm allowing multi-tier or system-wide switching and capacitor control actions is developed for large-scale, radial distribution networks. The service restoration problem is formulated as a constrained multiple-objective optimization problem. A solution algorithm designed to consider networks with predominately manual switches is developed which utilizes information calculated from three-phase power flow analysis to restore as much priority and total load as possible while requiring a minimal number of control actions and amount of geographic travel distance. Simulation results are presented for a 399 bus distribution network and compared to a service restoration algorithm which avoids multi-tier switching.

基于网络重构和电容控制的大型径向配电网多层业务恢复
针对大规模径向配电网络,提出了一种快速有效的服务恢复算法,允许多层或全系统范围的开关和电容控制动作。将服务恢复问题表述为一个有约束的多目标优化问题。设计了一种解决方案算法,该算法利用三相潮流分析计算的信息,在需要最少数量的控制动作和地理传输距离的情况下,尽可能多地恢复优先级和总负载。给出了399总线配电网的仿真结果,并与避免多层交换的业务恢复算法进行了比较。
