Embodiment Construction

[0088] The inventor of the present application has found through a large amount of research and practice:

[0089] In the existing technology, domestic and foreign researches on the integrated dispatching of power generation and utilization mainly aim at reducing the operating cost of the power grid, and there are few studies considering the benefits of both the power generation side and the user side at the same time, and from the perspective of the power generation side, most Most of the methods only consider wind power system, photovoltaic power generation system or traditional thermal power generation system alone, while few studies take wind power storage combined power generation system as the research object; there are also many studies from the perspective of the user side, on the controllable load and electric vehicle load. However, the optimal dispatch of controllable load and electric vehicles is mostly considered separately, and there are few studies on the comprehe...

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.

Description

technical field [0001] The invention relates to the technical field of energy Internet, in particular to an integrated scheduling method for power generation and utilization based on a wind-solar-storage combined power generation system. Background technique [0002] The development and utilization of large-scale wind energy and solar energy has led to an increase in the installed capacity of renewable energy, but it is difficult to accommodate wind and light, and there has been a serious problem of abandoning wind and light, and at the same time it has brought great challenges to the optimal dispatch of the power generation side. [0003] In the process of implementing the present invention, the inventor of the present application found that the method of the prior art has at least the following technical problems: [0004] In the existing technology, domestic and foreign researches on the integrated dispatching of power generation mainly aim at reducing the operating cost ...
