摘要

基于考虑有效性和方向性的发电机无功储备定义

提出了考虑静态并联无功补偿的最小发电机有效无功储备优化模型。采用Benders分解算法的思想

将原问题分解为正常运行方式下的主问题和预想非正常运行方式下的子问题

并设计了降低模型求解规模的子问题筛选算法

提高了Benders算法的求解效率。最后

由针对IEEE 39节点系统的算例分析验证了所提算法的有效性。

Abstract

Based on the effectiveness and directionality of generator reactive power reserve (GRPR)

an optimization model for minimizing effective GRPR considering static shunt reactive power compensation is proposed. Using the theory of Benders decomposition algorithm

the original problem is decomposed into a master problem that corresponds to normal operation condition and several sub-problems that correspond to anticipated contingency and stressed operation conditions. In order to reduce the scale of model solving

a screening algorithm for sub-problems is designed

which is capable of improving the overall model solving efficiency of Benders algorithm. In the end

case studies on an IEEE 39-bus system have verified the effectiveness of the proposed algorithm. This work is supported by State Grid Corporation of China.
