Research on the construction of a tariff mechanism for microgrid trading based on cooperative game analysis

Under the impetus of the energy internet and the new Selectricity reform policy, several microgrids have been built and operated in various regions of the country. Most of them are technology demonstration projects, and the internal market model is not yet mature. In this paper, a cooperative trading model is proposed, and cooperative game models are established for singleto-many and many-to-many trading scenarios with multiple participants. The example shows that the transaction between customers and distributed generators is influenced by the offers of all participants, and an aggressive offer strategy will bring more benefits; through the game, the distribution of collective benefits within the microgrid is optimal, and both sides of the transaction get the contracted tariff based on the optimal distribution, resulting in a win-win situation for both buyers and sellers.
