摘　　要：电力系统主要是通过调节发电机有功出力、机端电压、变压器变比以及无功补偿容量这4种控制变量来实现对其特定性能指标的优化,研究这些控制变量对系统性能指标的影响程度可为电力系统调度提供借鉴参考。以IEEE30节点系统为例,使用粒子群算法对此问题进行了研究,结果表明调节发电机有功出力对系统网损影响最大,调节机端电压对电压偏移影响最大。以IEEE118节点系统的计算结果再次验证了本文结论。The optimization of certain performance index of power system is achieved mainly by adjusting the active power output and terminal voltage of generators,transformer ratio and reactive power compensation capacity,The study of the influence level of these control variables on performance indexes of power system can provide reference for power system dispatching.This problem is studied using particle swarm optimization based on IEEE 30-bus system in this paper.The results show that adjusting the active power output of generators has largest impact on the power loss,while adjusting the terminal voltage of generators has largest impact on the voltage deviation.Finally,the IEEE 118-bus system is used to verify the conclusion again.
