基于灵敏度综合分析的含光伏配电网无功补偿位置选择

灵敏度分析的一个重要应用是无功补偿位置的确定。采用有功和无功灵敏度指标的综合分析，充分考虑了含光伏电站的配电网中有功功率和无功功率对节点电压的影响，利用灵敏度指标综合判别式的绝对值大小判断薄弱的线路，因为这些薄弱环节往往是安装无功补偿装置的首选位置。然后在确定的补偿位置安装静止无功补偿器（SVC），并应用修改后的IEEE9节点算例对本文提出的确定无功补偿地点的方法进行验证，结果表明该方法有效可行，补偿效果比较显著。

Reactive Power Compensation Location Selection of Distribution Network Containing PV Based on Comprehensive Analysis of Sensitivity

An important application of sensitivity analysis is to determine the location of reactive power compensation. The paper determines weak lines by using the absolute value of active and reactive sensitivity index based on comprehensive analysis, considering fully the influence of the active power and reactive power on node voltages in distribution network with photow）ltaic power station. These weaknesses are often preferred location for installing reactive power compensation device. Static Var Compensator （SVC） is installed at the determined compensation location. The determination method of reactive power compensation node presented in this paper is verified by IEEE 9-nodes numerical example, results show that the method is effective and feasible, and the compensation effect is significant.
