Abstract

The invention discloses an optimal scheduling method of a wind-light-water complementary power generation system containing cascade hydropower. The method comprises the steps: obtaining information ofa wind power plant, a photovoltaic power station and a cascade hydropower station, establishing an optimal scheduling model of a wind-light-water complementary power generation system containing cascade hydropower stations, proposing a wind-light-water complementary power generation increment benefit quantification method, and finally proposing a wind-light-water complementary power generation increment benefit allocation method. From the perspective of operation, the invention provides the optimal scheduling model of the wind-light-water complementary power generation system containing the cascade hydropower station, the model utilizes the natural complementary characteristics of wind power resources and illumination resources, the ability of the cascade hydropower station to regulate water resources as a whole is exerted, the wind power and photoelectric absorption ability is improved, and the reliability requirement of output electric energy is met.

Description

technical field [0001] The invention relates to an optimal scheduling method of a wind-solar-water complementary power generation system including cascade hydropower, belonging to the field of electric power. Background technique [0002] After large-scale wind power and photovoltaics are connected to the grid, the economic and safe operation of the power system is facing severe challenges. How to rely on cascade hydropower to develop complementary power generation of wind, solar and water clean energy and improve the consumption level of wind power and photovoltaics is an urgent problem to be solved. The existing literature studies on the optimal dispatching model of wind-solar-hydro hybrid power generation, mainly from the perspectives of wind-pumped storage complementarity, wind-small cascade hydropower complementarity, wind-solar-conventional hydropower complementarity, etc. The research on optimal dispatching model of power generation system is still in its infancy Co...
