摘要
提出考虑协调二级电压控制作用的静态电压稳定裕度计算最优潮流模型,重点解决各控制分区中含有多个先导节点的问题。模型中引入无功出力因子促使发电机无功出力裕度最大,引入多个互补约束方程来保证控制分区中的全部先导节点的电压都维持在设定值附近。优化模型的求解采用原对偶内点法,并在求解过程中使用稀疏技术加快计算速度。最后,对IEEE 39节点测试系统进行静态电压稳定裕度计算,结果表明,控制分区中含有多个先导节点能够提高系统的静态电压稳定性和系统在电压崩溃前的电压水平。
An optimal power flow model for the computation of static voltage stability margin, in which the effect of coordinated secondary voltage control （CSVC） is considered, is proposed to mainly focus on solving problem that there are multiple pilot buses in control partitions. The reactive power output factor is led into the proposed model to prompt the reactive output of generators to be the maximum, and multi complementary constraint equations are led in to make the voltages at all pilot buses in the control partition closed to setting value. The proposed model is solved by prime-dual interior point method, and during the solution the sparse technology is utilized to accelerate the＂ calculation. Computation results of static voltage stability margin by IEEE 39-bus System show that the control partition containing multiple pilot buses can improve the static voltage stability of power system and voltage level of power system before the voltage collapse.
