Economic Study of Wind and Solar Power Generation with Energy Storage Configuration

With the growth of new energy demand, energy storage technology has a broad application prospect in solving the intermittency problem of wind power generation, improving the stability of the grid, and reducing the operating cost. This research first established and solved an efficient wind-solar economic allocation model for wind and solar energy storage configuration and economic cost. It obtained a total power supply cost of 6466.35 yuan for wind and solar power generation without energy storage configuration. Then, by establishing a collaborative optimization model for wind, solar, and energy storage, the target cost optimization for the economical operation of quantitative energy storage configuration was carried out. Finally, a collaborative cost minimization model for wind, solar, and energy storage was established to obtain the optimal operation strategy for energy storage with minimized costs. The collaborative cost minimization model for wind, solar, and energy storage can effectively optimize the energy storage power of 377kW and capacity allocation of 1130kWh, which is of great significance in ensuring the coordinated allocation of power operation and economic benefits for wind, solar, and energy storage in the country.
