Research on Reactive Power and Voltage Coordination Control Strategy for Multi-wind Farm Connecting to Power Grid

EasyChair Preprint no. 921

Abstract

In view of the impact of large-scale wind power access on the safe and stable operation of power grid and economic dispatch, a coordinated control strategy for reactive power and voltage optimization of regional power grid with multi-wind farms connected to the grid is proposed. The control strategy considers the optimization of system voltage quality and network loss comprehensively, and uses genetic algorithm to solve the optimization problem. The genetic algorithm based on power flow calculation is improved by utilizing the information of reactive power and voltage sensitivity and reactive power loss sensitivity of regional power grid, which improves the calculation speed of the optimization algorithm and further enhances the real-time performance of reactive power coordination control. Taking a regional power grid in Hami, Xinjiang as an example, the simulation results show that the proposed strategy can effectively improve the voltage quality and network loss of the regional power grid.
