Research on Island Microgrid Master-Slave Mode

Article Preview

Abstract:

Based on island microgrid, using master-slave structure. VF inverter works as master, ensuring the stability of the voltage and frequency of microgird, PQ inverter works as slave, maximize the use of renewable energy sources. Design the controller for VF and PQ inverter respectively. PQ inverter use single current loop, VF inverter use voltage outer loop and current inner loop. Discuss the design of controller in detail. VF inverter and PQ inverter working in parallel in master-slave island microgrid. Simulation runs in Matlab Simulink environment, the result turns out this structure and design is workable and stable.
