摘　　要：在能源互联网和新电改政策的推动下,全国各地区现已建设运营了多个微电网。其中,大多为技术示范性项目,内部市场模式尚未成熟。为此,本文提出了合作交易模式,分别建立了多主体参与的单对多、多对多交易情形下的合作博弈模型,并采用核仁法对博弈模型进行了求解,得出交易电价。算例表明:用户与分布式发电方之间的交易受到所有参与者报价的影响,积极的报价策略将带来更多的收益;通过博弈,微电网内部集体利益分配达到最优,交易双方得到了基于最优分配的合约电价,购售双方达到共赢。Driven by the energy Internet and the new electricity reform policy, many 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. To this end, this paper proposes a Cooperative Trading model, and establishes the cooperative game model under the single-to-many and multi-to-many trading situations with multi-agent participation, and solves the game model by using the nucleolus method to get the transaction price. The example shows that the transaction between users and distributed generators is influenced by all participants’ quotations, and the active bidding strategy will bring more benefits. Through game theory, the distribution of collective interests within the microgrid is optimal, and the contract price based on the optimal allocation is obtained by both sides of the transaction, and the buyer and seller can achieve win-win situation.
