Micro-grid scheduling method and device based on renewable energy sources

The invention discloses a micro-grid scheduling method and device based on renewable energy sources. The method comprises the following steps: constructing a power generation model of the renewable energy sources in a micro-grid; predicting the power generation amount of the renewable energy according to the power generation model of the renewable energy, and constructing and solving a first objective function to obtain the maximum consumption amount of the renewable energy; and according to the maximum consumption amount of the renewable energy and the power generation operation cost of the micro-grid, constructing and solving a second objective function to obtain a micro-grid scheduling result. According to the method, the technical problem that economic dispatching cannot be realized while the renewable energy consumption of the micro-grid is solved in the prior art is solved, and it is ensured that the obtained micro-grid dispatching result can meet the consumption amount of the renewable energy and the p
