摘    要:孤岛是引入分布式电源以后在配电网中新出现的一种运行方式.根据配电网中负荷的重要程度,以等值有效负荷最大为目标函数,建立配电网孤岛划分的模型,并采用深度优先搜索和广度优先搜索技术求解该模型.结合配电网孤岛运行方式,对传统可靠性计算中的最小路法进行改进,使之适用于含分布式电源的配电网供电可靠性分析计算.通过对IEEE-RBTS Bus 6系统的仿真计算,说明本模型的有效性与实用性,计算结果表明,分布式电源合理接入配电网后,可以提高配电网供电的可靠性.

关 键 词:可靠性  分布式电源  孤岛  配电网

Abstract:Island is a new operating mode when the distribution network is incorporated with distributed generations.Based on the importance of the load an optimization model of distribution network islanding scheme is established,in which the maximum equivalent load is taken as objective function.A solution based on depth-first search and breadth-first search technology is given.By considering the islanding operating mode,the paper improves the minimal path method of the traditional reliability calculation and makes it suit to calculate the distribution network with distributed generation.The simulation of IEEE-RBTS Bus 6 system demonstrates the efficiency and practicability of the mode.The calculating results indicate that the distributed generation connected to distribution network can improve the reliability of the distributed system.
Keywords:reliability  distributed generation  island  distribution network
