Abstract:
In order to realize power balance in AC/DC hybrid microgrid island mode and make full use of distributed energy, this paper proposes a control strategy combining model prediction algorithm with bidirectional droop control for the control of bidirectional AC/DC converters to achieve fast and accurate power transmission between two subnets. The simulation results show that under the condition of AC/DC side of various power fluctuations, The control strategy can realize bidirectional power flow between subnets quickly and accurately, guarantee the power balance of the system, ensure the stability of the system voltage and frequency, reduce the steady state error of the system and realize the stable operation of hybrid microgrid.
