Analysis and Research for Capacity Credit of Large Scale Wind Farms and Influence on Reserve Capacity of East China Electric Power Grid

According to plan,the integration of wind power capacity into East China Electric Power Grid will reach to 10 GW in 2020,because wind power is stochastic and uncontrollable,the capacity credit of wind farms will become a faced question as making grid planning.Besides,large scale wind farms will influence on system regulating frequency and reserve capacity when they integrate into East China Electric Power Grid.According to some research results about above questions of foreign power grid and considering the working conditions of East China Electric Power Grid,the paper gives accepted capacity credit of wind farms when the wind power capacity of East China Electric Power Grid reach to 10 GW in 2020,and analyzes the smoothing effect of large scale wind farm generating electricity.Basing on this,the influence of large scale wind farms on regulating frequency capacity and reserve capacity of East China Electric Power Grid is analyzed.
