摘要: This paper proposes a method for islanding detection in microgrids with multiple parallel-connected inverters using high-frequency signal injection. In the proposed method, master inverter injects which is used by rest of detection, two distinguishing features: 1) The slave work current cancellation mode, what prevents interference and 2) case failure or significant changes grid, remaining will dynamically reassign roles, new being self-selected, based on deterministic performance criteria without need communications.
