Microgrid control method

The invention discloses a microgrid control method. The method comprises the steps of (1) monitoring a power grid in real time by a microgrid controller; (2) performing wind-light power forecast whena power grid fault is detected, performing step load control according to a real-time wind-light power forecast value and battery electric quantity, controlling wind-light power generation to enter anoff-grid running mode, and controlling an energy storage battery to discharge if wind-light power generation is not enough; (3) controlling wind-light power generation to enter a grid-connected modeto run when that the power grid is recovered is detected, charging stored energy, and simultaneously recovering each-stage load power supply; and (4) timely adjusting a running mode through monitoringwind-light power generation by the microgrid controller, maintaining power balance between power supply and a load, and preventing unfavorable influence of wind-light power generation fluctuation onthe power grid by combining e
