Master-Slave Control Strategy of Flexibly Interconnected Microgrid Clusters Under Gridconnected and Islanded Modes

As distributed generation systems are increasingly integrated on a large scale, research into microgrid control is becoming increasingly vital. The microgrid clusters, which are interconnected via a DC distribution network and share energy storage, represent a novel topology distinct from traditional microgrids. They offer numerous advantages and are of significant research interest. To begin with, the structure of the system under study is introduced, and the control objectives for both grid-connected and off-grid control are outlined. Subsequently, a master-slave control strategy for voltage source converters (VSC) is proposed. Finally, simulations are conducted using Matlab/Simulink, and the results are analyzed in detail.
