摘　　要：大量的分布式电源接入配电网会对配电网的可靠性带来深刻的影响。提出以分布式电源、负荷所组成的微网为分析对象,从微网的角度分析微网对配电网可靠性的影响。提出发电负荷率(GLR)的概念,通过序贯的蒙特卡洛模拟算法,考虑发电负荷率的因素,分别分析微网内部分布式电源类型、容量以及微网运行方式对配电网可靠性的影响。算例结果表明,微网能够提高配电网的可靠性,且不同类型的微网对其可靠性影响程度不同。Extensive access of distributed generators（DG） has greatly impacted the reliability of distribution network. Taking microgrid （ composed of DG and load） as research subject, this paper aims to analyze the impacts of microgrid on the distribution network reliability. The concept of generating load rate （GLR） is defined and sequential Monte Carlo simulation algorithm is used to analyze the impacts of the types of DG, capacity and operation modes of micro- grid. Calculation results show that microgrid can improve the reliability of distribution network, and the different types of microgrid have different effects on the distribution network reliability.
