Abstract: This paper proposes a smart grid system operation strategy dominated by power retailers. The power retailers output users' real-time electricity price according to the electricity supply price and generation capacity with the goal of maximizing revenue. On the power supply side, the online order of different types of power suppliers is optimized, and the robustness analysis of the uncertain output of wind power photovoltaic energy is considered to optimize the interests of power suppliers on the basis of maintaining a balance between supply and demand. On the demand side, users are classified according to the scale of power consumption, secondary classification is carried out according to the importance of power supply, and particle swarm optimization algorithm is used to solve the optimal power consumption of users. The simulation results show that the power retailers maintain the balance of interests of all parties in the power system, which has potential benefits for both suppliers and users.
