Research on Control Strategy for Reactive Power Optimization of Voltage-source Inverter in Micro-grid
摘要
Abstract
By using droop control mode, the voltage-source inverter in micro-grid can conveniently realize reasonable distribution of local active power load, but it can not realize reasonable distribution of reactive power load and effective restriction on reactive power circulating current.In allusion to the problem of imbalance of reactive power, this paper proposes an improved droop control strategy based on micro-grid coordination controller.This strategy can monitoring output of the voltage-source inverter by unified micro-grid coordination controller and realize optimized configuration of active power load and reactive power load of the micro-grid by means of the improved droop control method as well as ensure stable operation of the micro-grid under island mode.PSCAD/EMTDC simulation verifies validity of the proposed control strategy.关键词
