Study on the strategy of multilateral electricity trading among provinces in Northeast China

Northeast China is an important birthplace of China's power market reform. The development of its power market trading mode is of great significance to the deepening and promotion of China's power market reform. Therefore, taking Northeast China as an example, this paper analyzed the characteristics of the current inter-provincial multilateral trading market, and explores the influencing factors of the scale of inter provincial multilateral trading in Northeast China. Combined with the characteristics of power grid structure and resource endowment in Northeast China, the calculation model of multilateral trade electricity in Northeast China is established. On this basis, taking the optimal economic benefits, resource allocation fairness and demand satisfaction index as the objectives, and taking the upper limit of trading volume and the balance of electricity and electricity as constraints, the paper puts forward a strategy suitable for multilateral electricity trading. Finally, the effectiveness of this strategy is verified with the actual data of Northeast China power market.
