摘要

近年来光伏发电逐渐受到广泛的关注，光资源的波动性和间歇性特性使得准确评估其可靠性十分重要。文中分析了分布式光伏发电系统的结构以及出力特点，以此为基础建立了综合考虑能源约束和系统结构特点的六状态可靠性模型，并从时间、出力、系统这3个层面建立了综合评价系统可靠性的指标体系。最后，采用实际系统算例进行了计算分析，验证了所提出方法的合理性和可行性。结果表明，该模型及指标体系能够全面反映分布式光伏发电系统的运行特点、出力水平和故障情况，以及实际运行可靠性。

Abstract

In recent years，the photovoltaic（PV）power system has gradually attracted widespread public attention.The rational reliability evaluation of PV power system is very important because of its volatility and intermittence.Based on an analysis of its structure and output characteristics，a six-state reliability model is developed with the energy constraints and the characteristics of system structure of the distributed PV power system taken into account.In addition，an index system is developed for comprehensively evaluating system reliability with respect to the timing，the output，and the system.Test results of an actual PV power system show that the reliability model and index system are rational and feasible and capable of reflecting the operation characteristics of the distributed PV power system，its output，fault characteristics and the reliability of its actual operation.
