In view of the negative impact of large-scale wind power and photovoltaics directly integrated into the power grid on peak shaving of the system, accompanied by the problems of high wind abandonment and high abandonment rate, a joint peak shaving solution is proposed to combine a cascade hydropower station in Hubei with nearby wind farms and a photovoltaic field into the power grid by using the hydropower output channel. Firstly, the necessity and feasibility of joint dispatch of cascade hydropower stations, wind power and photovoltaics were analyzed, and the cascade water-wind-light joint peak shaving strategy was proposed. A short-term dispatch model with the minimum mean square error of the system remaining load as the objective function was constructed. Finally, the shrinkage factor and improved particle swarm algorithm optimization were used to solve the problem. Through the simulation, the wind and solar power stations and the cascade hydropower stations jointly participate in the peak shaving of the system, the peak shaving effect is better. The improved PSO has better optimization accuracy and convergence speed. It provides a reference for implementing the combined peak shaving strategy of the cascade hydropower station with surrounding wind and photovoltaic field in the future.
