Load sharing and common bus voltage control strategy for DC microgrid
摘要
Abstract
U-I droop schemes possess excellent adaptability and scalability,which is suitable for voltage control and load sharing of autonomous DC microgrids.However,it has not been given how to make a trade-off between the steady-state errors of the common bus voltage control and the accuracy of load sharing.The paper presents an adaptive control scheme for autonomous DC microgrids.The proposed scheme is accomplished by voltage reference regulation combined with current reference regulation.The small signal model of the microgrid under the proposed scheme is formed for the stability analysis.Simulation results show that the load is shared among DG units at the desired ratio and the voltage of common bus is restored accurately by the proposed scheme during load fluctuation,DG unit fault and change of system parameter.关键词
