火电灵活性改造的现状、关键问题与发展前景

Status,Critical Problems and Prospects of Flexibility Retrofit of Thermal Power in China

火电灵活性改造作为"十三五"电力规划的亮点被提出,但"十三五"期间在各地的发展态势相异。从长久来看,火电作为我国发电容量主体,仍将在多数地区提供最主要的调节容量。为此,文章全面梳理了火电灵活性改造的国内外发展历程,总结了影响火电灵活性改造的关键技术、经济与机制要素,提出了国内开展的典型改造模式,并对我国火电灵活性改造的未来发展前景和重点研究问题进行了预测和分析。研究表明,随着各类灵活性市场的建立,我国火电灵活性改造将由政策主导向市场主导过渡,灵活性也将成为火电乃至整个电力系统从规划、设计到运行的核心指标,构建适应中国特色的火电灵活性改造技术标准与规划体系将为我国电力系统成功转型提供重要基石。

The flexibility retrofit of thermal power has been proposed as a highlight in the 13 th Five-Year Power plan,but the development trend during the 13 th Five-Year Plan period in different regions is diverse.In the long run,thermal power,as the main body of China’s power generation capacity,will still provide the most important regulation capacity in most regions.Thus,this article comprehensively sorts out the domestic and foreign development history of flexibility retrofit of thermal power,summarizes the key technical,economic,and mechanism factors that affect its progress,proposes typical flexibility retrofit models,and discusses its future development prospects and key research issues.The investigation shows that,with the establishment of various flexibility markets,flexibility retrofit of thermal power in China will transit from policy-oriented to market-oriented,and flexibility will also become the core indicator of thermal power and even the entire power system from plan,design to operation.It will be an important cornerstone of the successful transformation for China’s power system building the technical standards and planning system with Chinese characteristics for thermal-power flexibility retrofit.
