Optimization and control strategy of MCR reactive power allocation in urban power grid

Abstract

Abstract Aiming at the defects of the traditional reactive power compensation method in the original system of urban power grid, such as large difference in compensation capacity and single form, a configuration optimization strategy based on MCR reactive power compensation device is proposed. The optimal compensation point is evaluated by using the comprehensive degree index of voltage stability, and the reactive power optimization mathematical model of power system is established. The optimal reactive power configuration is obtained by optimizing the parameters of the mathematical model combined with particle swarm optimization algorithm. Finally, the dynamic reactive power compensation for 220KV level regional node system is added, according to the proposed reactive power configuration optimization scheme, to conduct simulation experiments, and the results show that the proposed method is reasonable and effective.
