Abstract:

The flexibility retrofit of thermal power has been proposed as a highlight in the 13th Five-Year Power plan, but the development trend during the 13th 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.

Key words: flexibility of thermal power, flexibility retrofit, peaking capability, flexibility market
