随着售电业务的放开，售电市场逐步成型，社会资本的进入也导致售电公司越来越多。对电力市场形成初期售电商之间的市场合作行为进行了研究，引入博弈理论，构建了不同情景下的售电商市场行为的博弈模型，探讨了售电商之间合作的可行性。仿真分析表明：符合合作条件的售电商之间通过合作可以提高各自的利润：电量预测偏差越大的售电商对交易单位成本的敏感性越大。

With the open of electricity sales business, electricity sales market is gradually forming, and more and more electricity sales companies are being established as a result of the entry of social capital. A study is made on the market cooperation between electricity suppliers in the early stage of electricity market. By introducing the game theory, a game model of the market behavior of electricity suppliers is constructed under different scenarios to explore the cooperation feasibility between different electricity suppliers. The simulation results show that electricity suppliers can increase their profits through cooperation, and the greater the electricity forecasting deviation is, the higher the sensitivity of the unit transaction cost is.
