Method for obtaining decision variables for determining virtual power plant scheduling strategy

The invention discloses a method for obtaining decision variables for determining a virtual power plant scheduling strategy. The method comprises the steps of obtaining reference information for renewable energy power generation, a target function of a virtual power plant and operation constraint conditions of the virtual power plant; the reference information comprises power generation confidence interval information and electricity price scene information, and the objective function is used for obtaining the maximum income value of the virtual power plant; according to the reference information, the target function and the operation constraint condition, constructing a target optimization scheduling model of the virtual power plant; and obtaining a decision variable according to the target optimization scheduling model. According to the method, when the target optimization scheduling model of the virtual power plant is constructed, the power generation uncertainty of renewable energy sources, the market ele
