摘　　要：分布式电源接入电网后,对配电系统将会产生很大影响,使原有配电系统可靠性计算模型和评估方法发生改变。文中提出了一种基于蒙特卡洛方法的分布式电源接入配电系统后的可靠性分析方法。该方法主要针对分布式电源与系统电源并列运行情况,重点考虑了分布式电源在配电网中的作用,以及在系统发生故障时分布式电源对供电负荷的转带策略等因素。通过实际仿真算例的分析,验证了该方法的有效性。With high penetration of distributed generation connected to the grid, distribution system will have some huge impacts, and system reliability calculation models and assessment methods are changing. Based on Mento-Carlo method, a reliability analysis method for distribution system with distributed generations was proposed in the paper, which focuses on the mode of distributed generation in parallel to system power supply. Functional role of distributed generation in the power distribution system failure and distributed power adapter with load strategies were analyzed in this method. Cases simulation analysis was used to verify its effectiveness.
