Due to the influence of the large-scale grid-connection wind farm with randomness, volatility and counter-peak on grid peak shaving and scheduling, the combined operation strategy of concentrated solar power system with thermal storage and wind power is adopted. By using the complementarity of solar thermal and wind power output as well as the dispatchability of heat storage, the wind power output fluctuations can be smoothed, the peak-valley load difference of power grid and the cost of thermal power load can be reduced, as well as avoiding to abandon the wind. Based on the operation mechanism analysis of the solar thermal power station, the power grid scheduling model of the combined system is established. The particle swarm optimization algorithm is applied to solve the model and realize the optimization of economic dispatch. The feasibility and rationality of the scheduling strategy and model is validated by simulation example analysis.
