Abstract：Wind power generation has the characteristics of random fluctuation and intermittence. The energy storage equipment can be used to smooth the output of the wind farm, which can replace thermal power plants and provide a reliable load supply for the grid. Firstly, based on the wind resource characteristics, we define the thermal power replacement capacity and load supply capacity of wind farms, which reflect the ability of wind farms to output smoothly and supply loads reliably. Given wind resource data and confidence probability requirements, thermal power replacement capacity and load supply capacity can be solved by mixed integer linear programming. According to the requirements of the thermal power replacement capacity and load supply capacity, we construct an optimal configuration method for MW/(MW·h) parameters of the energy storage. This method calculates the boundary of the parameter feasible region and then determines the range of optimal parameter configuration according to the energy storage cost coefficient. In the case study, the historical data of wind farms in Guangdong province is used. It shows that our method can determine the optimal parameter configuration of energy storage quickly, while taking into account the economy and the reliability and stability of the power supply.
