Abstract: In order to support the efficient and stable operation of inter-provincial electricity spot trading, it is urgent to develop operation technologies that adapt to the characteristics of inter-provincial electricity spot trading, and achieve the efficient and coordinated operation of various markets. First, the paper introduces the background and trading mechanism of inter-provincial electricity spot trading, analyzes the technical challenges faced by market operation, constructs an operation functional framework for inter-provincial electricity spot trading, and designs a data flow based on wide-area distributed parallel technology. On this basis, multiple operation technologies are proposed, including the wide-area collaborative interaction technology, the interprovincial electricity spot trading clearing technology that supports global bidirectional trading, the multi-stage security verification technology based on model reconstruction, and the full-process auxiliary decision-making analysis technology based on the module flexible linkage. Finally, the engineering application of the described operation technologies is introduced, and the operation technologies that need further breakthroughs are prospected combined with the evolution direction of the future electricity spot market.
