Considering the characteristics of hydropower in Chongqing and the on-grid electricity price of power generation, water and wind power, and the time-of-use electricity price of users purchasing electricity, the model of Chongqing large-scale ice storage air-conditioning is established and is optimized based on the minimum power purchase cost of the power grid and the minimum operating cost of ice storage air-conditioning. The goal is to dispatch generators and ice storage air conditioners to maximize the benefits of the grid and users, while reducing the abandonment of water and wind power. The feasibility and effectiveness of the proposed control strategy are verified by simulating the control of ice storage air conditioning under different cooling load requirements.
