Abstract: As the global trend to low-carbon power system transition,under the current power market framework,whether the market mechanisms can release correct price signals to ensure the adequacy of flexible power supply and reliable backup capacity in power system,whether the capacity remuneration mechanism （CRM,or CM） is necessary,and how to design the CRM are important issues for maintaining the sustainability of the power market. This paper firstly discusses the possible generation adequacy problems that may arise when a single energy market model is adopted for a high proportion of new energy power system,and quantifies the problems by constructing a screening curve model for power generation technology.Secondly,this paper summarizes the mechanism and specific contents of capacity remuneration mechanism design in foreign mature power market,and extracts three key elements of capacity remuneration mechanism design. Lastly,this paper points out the problems of capacity market mechanism design in China’s power market and provides forward relevant suggestions.
