Power generation and utilization integrated scheduling method based on wind-solar-energy-storage combined power generation system

Abstract

The invention discloses a power generation and utilization integrated scheduling method based on a wind-solar-energy storage combined power generation system. The method comprises the steps: respectively building a wind-solar-energy storage combined power generation system model, a power grid side model and a user side model, and then building a power generation and utilization integrated scheduling model; when preparing to perform scheduling, collecting current load information, photovoltaic power generation conditions and wind power generation conditions, and calculating the wind-solar powergeneration capacity according to the photovoltaic power generation conditions and the wind power generation conditions; determining the load type of the declared electricity price according to the relationship between the wind-solar generating capacity and the load and whether the electricity price of the power grid is higher than a threshold, and declaring the electricity price by the load of the corresponding type; and taking the first objective function, the second objective function and the third objective function as optimization objectives according to the electricity price declarationinformation, and performing scheduling by utilizing the electricity generation and utilization integrated scheduling model to obtain a scheduling result. According to the method, the scheduling effectcan be improved, and the method has important practical significance for improving the renewable energy consumption capacity and optimizing power generation and utilization resources.
