With the high penetration rate of wind power,Jilin province is now facing a severe bottleneck in wind power accommodation,which has seriously restricted further development and utilization of wind energy resources.The factors causing the bottleneck include fluctuation of wind power,load level of power grid,and heating demand in the winter season.In order to solve the problem of wind power curtailment,development of intelligent wind power dispatching system which is suitable for strongly fluctuating power supply,and utilization of emerging technologies,such as thermal energy storage technology and wind-energy heat supply technology,to improve the regulating capacity of power grid and increase the scale of electric load are two effective ways.According to the present situation of large-scale wind power integration of Jilin Province,this paper introduces the current situation and existing problems of wind power forecasting technology,thermal energy storage technology and wind-energy heat supply technology,and expounds the application and development trend of these key technologies for wind power accommodation.
