Aiming at the problems of poor operation stability of spinning reserve capacity of high proportion wind farms and low transmission efficiency of day-ahead power generation plan,a spinning reserve capacity optimization model was designed.Use high-voltage direct current(HVDC)technology to formulate an optimal power generation plan to maximize the power transmission of the wind farm;by use of gravitational search algorithm(GSA)optimization,the operation process of the entire wind power system was analyzed,and the result was to screen out the optimal solution based on the feedback of user satisfaction,and increase the efficiency of wind power transmission.The experiments show that the transmission efficiency of this study is above 85%;the stability range of this design is 40~60 Hz,and the transmission efficiency can reach up to 90%,which greatly improves the optimization capability.
