为实现事故预案匹配,加快供电恢复策略生成速度,提出一种基于人工免疫聚类算法的配电网故障状态相似性分析方法。首先,将故障恢复策略相似作为相似故障状态的评价标准,构建配电网故障相似特征指标集,包括负荷失电量、联络线备用容量以及失电负荷-源点最短电气距离。在此基础上,鉴于聚类分析能够揭示无标记训练样本数据的内在关联特征,提出一种基于人工免疫聚类算法的故障相似状态匹配方法。最后,应用免疫系统信息处理机制对算法进行改进,通过引入免疫浓度机制、变异机制,弥补k-means聚类算法对初始中心点位置敏感的不足。算例分析表

传统的输电系统可靠性分析以整个系统为研究目标,无法正确评估局部系统的停电风险。本文从负荷角度出发,结合数据驱动方法提出了基于发电机和负荷节点之间的连通度的节点运行风险评估指标——节点连通度。该指标采用数据驱动的方法,通过基于历史数据的学习及节点的局部测量数据和系统拓扑信息得到。同时为了提高指标精度,本文通过加权最小二乘法进行回归分析。该指标随着运行压力的增加而下降,对应描述了负荷节点可靠性不断下降直至发生甩负荷的过程。通过对IEEE-118节点算例进行仿真分析,验证了指标的有效性。
