Study on Regional Power Spot Market Trading Mechanism of China Southern Grid to Promote Green Energy Consumption

As the country’s only regional electricity spot market pilot, the southern regional electricity spot market needs to comprehensively consider the natural resource endowment of the East and west of the southern region, the supply and demand of provinces, and the complexity and realizability of the clearing model. From the perspective of combining scientific research with engineering practice, this paper first establishes the overall framework of regional power spot trading; Then the South Grid and provincial grid two-level scheduling joint transaction mechanism is designed; Finally, a regional spot clearing model considering the priority of new energy consumption is constructed to provide technical support for regional spot development.
