In microgrid stability control, islanding operation is the core content, and unplanned islanding detection is a precondition for stable islanding operation of the microgrid during fault disassembly. A hybrid islanding detection method based on voltage-phase droop control is proposed in this paper. It combines passive over/under frequency, over/under voltage detection method and active islanding detection method which is based on positive feedback together. The unplanned islanding is perceived in real time. Through load scheduling, the power balance in the microgrid can be realized quickly. In addition, the power supply continuity of the load in the microgrid can be guaranteed. The model of microgrid system is built in Matlab/Simulink, and the proposed method is simulated and verified under multiple complex working conditions.
