This paper proposed a dynamic reactive power optimization model of receiving power system containing infeasible voltage-violated buses. First, the reactive power compensation bus was categorized, and the basic concept of system reactive power compensation bus was proposed. According to occurrence of the infeasible voltage-violated buses in the time period, the daytime was divided into feasible and infeasible time periods; and then constructed a dynamic reactive power optimization model of receiving power system. This model consisted of two sub-models, infeasible and feasible time-periods of dynamic reactive power optimization models. For the 1st sub-model, a 2-stage solution algorithm was proposed based on the homogeneous interior point method (HIPM) and parallel cooperative co-evolutionary differential evolution algorithm (IPCCD-EA). For the 2nd sub-model, the immune genetic algorithm (IGA) was hired. Finally, a practical 110 kV 25 bus system was used for simulating and verifying that the proposed method was effective.%提出一种含电压不可行节点的受端电网动态无功优化方法.首先对无功补偿节点进行了分类,并提出系统无功补偿节点的基本概念,然后以某时段是否出现电压约束不可行节点为依据,将全天所有时段划分为可行时段簇和不可行时段簇;并在此基础上,构建了含电压不可行节点的受端电网动态无功优化模型.该模型包含了不可行时段簇和可行时段簇的动态无功优化两个子模型,对前者,该文提出了一种基于同伦内点法和并行协同进化算法的两阶段求解算法;对后者,采取免疫遗传算法求解.最后通过实际25节点的110 kV高压配电网仿真分析,验证了所提方法的有效性.
