吉林风电消纳关键技术的研究现状与发展趋势

 吉林电网风电渗透率高，受风电随机波动性、电网负荷水平以及冬季社会供热需求等因素的制约，吉林风电面临着严峻的消纳瓶颈，已严重制约风能资源的进一步开发利用。开发适应强波动性电源的智能风电调度系统，利用储热及风电供热技术等新兴技术，提高电网调节能力，增加用电负荷规模，是破解风电消纳的有效途径。本文结合吉林风电大规模联网面临难题，介绍了风电功率预测技术、储热技术和风电供热技术研究现状及存在问题，阐述了风电消纳相关技术的应用进展和发展趋势。

Research status and development trend of key technologies of wind power accommodation in Jilin province

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.
