摘要微电源越来越多的被接入到配电系统中,在改变配电网运行方式的同时也给配电网的可靠性评估方法带来影响。本文重点分析了负荷点与电源间的连通性,在充分考虑微网运行模式的基础上,针对负荷点故障类型提出了基于馈线路径集合的判别方法。其次分别提出了微网并网协调运行方案以及离网模式下的负荷削减策略。最后通过时序蒙特卡洛模拟法计算并网型微电网的可靠性指标。以改进的IEEE RBTS BUS6系统进行算例分析,验证了所提出方法的有效性。

Abstract：More and more micro-grid is connected to the distribution system, in the way of changing the distribution network operation, but also to the distribution network reliability assessment methods to bring the impact. This paper focuses on the analysis of the connection between the load points and the power suppliers, and based on the full consideration of the operation modes of the micro-grid, this paper proposes a method to determine the type of the feeder path set based on theload points.According to the two different operation modes of micro-grid, the coordinated operation scheme of micro-grid and the load reduction strategy are proposed.Finally, the reliability index of grid-connected micro-grid is calculated by sequential Monte Carlo simulation method.By the improved IEEE RBTS BUS6 system example analysis, the effectiveness of the proposed method is verified.
