A multi-timescale market clearing model considering reserve demand curve

With the advancement of the dual-carbon goal， the integration of a large amount of new energy sources has posed new challenges to power balance of the system. In this context， research on methods for system reserve provision considering both economy and reliability has garnered significant attention. In this regard， a multi-timescale market clearing model considering the reserve demand curve has been constructed， so that the reserve clearing results take account of both economy and reliability. Besides， diverse reserve resources across multiple time scales are considered， allowing for the balance between supply and demand of the reserve under multiple time scales through coordinated interactions among these resources. Finally， it is verified by a case study that the proposed model realizes a rational allocation of reserve， thereby improving the operational economy， safety and reliability of the system.
