Park source-load-storage collaborative optimization scheduling method and device, terminal and medium

The invention discloses a park source-load-storage collaborative optimization scheduling method and device, a terminal and a medium. The method comprises the following steps: acquiring new energy unit output, gas turbine output, park network load and energy storage device parameters in a park as park system initial data; establishing a park source-load-storage collaborative optimization scheduling model with the lowest park comprehensive operation cost as an optimization target; considering the output characteristics of each unit, the load demand of the park and the peak regulation and valley filling effect of the energy storage device, and constructing constraint conditions of the scheduling model; and solving the scheduling model based on the constraint condition and a formulated scheduling strategy to obtain an optimized source-load-storage scheduling plan. The problems of full consumption of new energy and interaction between the park and the external power grid can be effectively solved, the peak regulat
