Abstract:

Under the drive of the "Dual Carbon" goals, integrated source-grid-load-storage projects, with their capacity for localized renewable energy consumption, have garnered significant attention. However, the inherent source-load balance within these projects conflicts with existing electricity pricing mechanisms, posing risks such as underpayment of transmission and distribution tariffs and mismatched system operating costs, which may compromise grid revenues. To address these challenges, this paper first systematically examines the construction and operational mechanisms of integrated source-grid-load-storage projects, distinguishing their similarities and differences from other aggregated entities. Secondly, it summarizes their market participation mechanisms and proceeds to dissect the shortcomings present in existing market access regulations and market-based trading systems. Furthermore, the study analyzes existing benefit distribution models among internal stakeholders. Finally, guided by national and regional policy directions, a design framework for market access mechanisms is proposed, offering theoretical foundations and practical pathways for standardizing the development of integrated source-grid-load-storage projects and refining electricity market mechanisms.

Key words: integrated source-grid-load-storage project, aggregated entities, market-based trading, benefit distribution, market access mechanisms
