Control Strategy of Interlinked Converter for AC DC Microgrid
摘要
Abstract
The hybrid AC DC microgrid is an important part of the future smart grid.This paper is concerned with the typical topology and operation mode for the hybrid AC DC microgrid.Then the power balance relationship in each operation mode is analyzed in detail.Because of the large impedance ratio in the low voltage grid a voltage and active power control system is designed and the power exchange and control of the interlinked converter is enunciated.Finally a new AC DC droop control strategy is proposed.The strategy gives the power-voltage droop relationship based on the function of the capacitor in the power transmission between AC side and DC side.The proposed control algorithm is verified on a PSCAD EMTDC simulation platform which shows that the interlinked converter can accurately maintain the power balance between the AC side and DC side based on the voltage information of both sides thus guaranteeing the voltage quality of the AC and DC microgrid.关键词
