摘　　要：分布式电源接入电网后,将使原有配电系统可靠性计算模型和评估方法发生改变。为此,提出一种考虑分布式电源影响的配电系统可靠性的计算方法。该方法是对传统配电网最小割集法的改进,充分考虑了分布式电源及配电网元件可靠性模型特性、分布式电源在配电系统故障时的作用和分布式电源转带负荷的策略等因素。通过IEEE-RBTS仿真算例的分析,验证了该方法的有效性。Insertion of distributed generation into power grid may change reliability calculation model and estimation method of original distribution system. Therefore, this paper proposes one calculation method for distribution system reliability con- sidering of distributed generation. This method is an improvement based on minimum cutest of traditional distribution net- work which fully considers distributed generation and characteristic of reliability model of components of distribution net- work. Meanwhile, this method takes into account of role of distributed generation when distribution system is out of order and strategy of transformation of distributed generation to on-load. By analysis on IEEE-RBTS simulation example, it veri- fies effectiveness of this method.
