Model construction of pumped storage to promote wind-photovoltaic consumption considering uncertainty of wind-photovoltaic output

Abstract

With the continuous development of renewable energy in China, to improve its competitiveness in the power market, this paper considers the participation of pumped storage power plants in renewable energy generation system on the basis of wind-photovoltaic complementary joint dispatching, and then proposes a wind-photovoltaic-pumped storage joint dispatching optimization method considering the uncertainty of wind and solar output. This method takes the minimum wind and solar curtailment as the goal, considers the operation constraints of wind-photovoltaic generating units and pumped storage generating units, and establishes a coordinated dispatching model, which provides the basis and theoretical basis for formulating the output scheme of the coordinated dispatching of wind, photovoltaic and pumped storage.
