Secondary voltage control is important for hierarchical voltage.It isan efficient way to power system for voltage/var control.It will improvethe power system's voltage level and the stability.It will avoid or delaythe voltage collapse. In this paper,we select the pilot nodes by improved simulated annealingalgorithm,then build the dispersed secondary voltage control systemmodel,select the control var resources by sensitivity matric.We show twodifferent control laws,one is based on the sensitivity between pilot nodevoltage and control var var resource output,the other includes the varoptimization,then computer the corresponding parameters. At last we do somesimulations to show that the previous work is right. Wang Kaipeng(Electric Power System and Automation) Directed by prof. Gao Shu...
