摘要：
The rapid development of renewable energy under the goal of "carbon emission peak and carbon neutrality" brings the problem of inertia scarcity, and it is increasingly important to guide the reasonable medium- and long-term investment to ensure the abundance of inertia. However, the current capacity market mechanisms only coordinate the balance of electric power and power quantity, and they are difficult to distinguish the differences between the different types of power sources in supporting the system inertial. Therefore, in this paper, the inertia adequacy is incorporated into the general concept of generation capacity adequacy. Firstly, the concept of inertial demand is clarified, and an evaluation method for inertia demand is proposed based on the frequency security constraints. Secondly, the inertia constraints are added to the original capacity clearing model, and the corresponding capacity pricing method and revenue allocation mechanism are designed, aiming at discovering the medium- and long-term value of inertia by market-based means. The case results show that the proposed pricing method for the capacity market considering the inertia demand can help form the reasonable investment return, promote the optimization of development scale and structure of power sources, as well as guarantee the system inertia adequacy. © 2023 Automation of Electric Power Systems Press.
