Electricity Trading Strategy for Home Users Based on Coalition Cooperation Game

Only by optimizing the energy storage and electric vehicle charging and discharging behavior of a single home user, its operation pattern has low consumption rate of renewable energy and low utilization rate of energy storage, which cannot solve the problem of power supply and demand imbalance of multiple home users in the user group. Therefore, this paper proposes a power trading strategy of home users based on coalition cooperative game. The load model of prosumer including wind power, photovoltaic, energy storage and electric vehicles are constructed, and on this basis, the cooperative game model of home-home user trading price coalition is proposed, and the characteristic function of cooperative game is calculated as the basis of the benefit distribution of home users. The simulation results show that the trading strategy can effectively motivate home users to participate in power trading in the power sharing user group composed of small-scale home users, and bring considerable benefits to consumers and prosumers.
