The invention provides an energy management control method for a wind and light storage micro-grid system, and the method comprises the steps: S1, obtaining the actual photovoltaic power generation amount and the actual wind power generation amount, and calibrating a real-time wind power calculation coefficient; s2, presetting the priority of each load, and obtaining the real-time state of each load; and S3, calculating a difference value between the actual generating capacity and the total electric quantity required by the load in the open state, and performing corresponding processing. According to the method, the predictability of the system on the actual generating capacity can be increased by predicting the real-time calibrated wind generating capacity, different processing is performed on the load and electric quantity distribution according to the relationship between the actual generating capacity and the total electric quantity required by the load, and then different priorities are set for the load,
