Distributed Energy Trading Mechanism Based on Supply-Demand Ratio Pricing and Fair Clearing

For distributed energy systems, an energy trading mechanism involving shared energy storage is proposed. This mechanism sets the internal transaction price according to the supply and demand of the system, and encourages the producers and consumers to adopt the optimal sharing strategy with the energy suppliers to maximize the system benefits and achieve the optimal social welfare. At the same time, the clearing algorithm based on the ideal profit realization rate is adopted to ensure fairness among participants and improve user satisfaction. The results show that the improved supply-demand pricing mechanism can effectively stimulate the enthusiasm of producers and consumers to participate in the market, and the shared energy storage trading mechanism can significantly improve the social welfare of the system. The clearing scheme based on the ideal profit realization rate can distribute profits according to the contribution degree of prosumers, and ensure the fairness of the system trading mechanism.
