and Voltage Control Yu Zhao1,2.£¬Zhao Dengfu1£¬Xia Jingde3£¬Du Zhengchun1 (1. School of Electrical Engineering, Xi'an Jiaotong University, Xi'an 710049, China; 2.

Shandong Kehui Electric Company Ltd., Zibo 255087, China) Abstract£ºThe equivalent differential convertions of the constraints on the times with nonª²differential control variables and the constraints on power equations with discrete variables for the dynamic optimal reactive power and voltage control are demonstrated, where the quadratic penalty function is formed with the discrete variable in the control variables and introduced into primalª²dual interior point algorithm to realize the gradual discretization of discrete variables during the optimization procedure. Then a complete mathematical model of dynamic optimal reactive power and voltage control based on the nonlinear interior algorithm is established. The results show that this scheme outperforms dynamic programming and genetic algorithm, and the times of iteration do not increase with the expanded net scale. It is applicable to both transmission system and distribution system.
