Research on Capacity Market Trading Mechanism Adapted to the Development of Flexibility Resources under the New Power System

In the wave of global energy transition, a new type of power system has emerged, which is notably characterized by a high proportion of renewable energy access, extensive use of power electronic equipment and diversified energy consumption. However, the intermittency and volatility of renewable energy sources pose serious challenges to the balance and stability of the power system, which makes the need for flexibility resources more and more urgent. Capacity market, as an important part of power market, plays a key role in guiding the rational investment and effective development of flexibility resources. This paper discusses the capacity market trading mechanism to adapt to the development of flexibility resources, and through the construction of mathematical models and detailed analyses of examples, it comprehensively analyzes the significant role and practical effects of this mechanism in optimizing the allocation of electric power resources, guaranteeing the reliability of the electric power system, and promoting the development of flexibility resources.
