风能的间歇性和波动性给风力发电大规模并网应用带来了不利影响,利用储能技术能够很好地解决该问题,然而昂贵的成本一直是制约储能技术应用的瓶颈。文中提出了基于压缩空气储能(CAES)的风电场功率调节系统的额定功率以及容量的设计,在满足风电并网标准的前提下尽可能减小储能装置的规模,并利用仿真加以分析验证。建立了CAES装置效益评估模型,将CAES电站与传统的火力调峰机组进行比较,分析结果表明CAES电站具有良好的经济效益。
The intermittence and fluctuation of the wind energy results in many adverse impacts on current large-scale utilization of wind power.Storage technology is an effective way to solve this problem,however the expensive cost has been the bottleneck of large-scale energy storage application.This paper puts forward a method to evaluate the power rating and energy capacity of wind power regulation system based on compressed air energy storage(CAES),that is to minimize the size of the energy storage device under the premise of meeting the standard for wind power integration.Results have been analyzed by using simulation software package.Meanwhile,this paper has established a benefit assessment model for CAES.Compared with traditional fossil-fired power generation units,CAES has considerable benefits.
