With the proliferations of photovoltaic power, energy storages and electric charging stations, how to coordinate their operations to improve social welfare is a burning and open problem. This paper proposes a coordinated operation model for PV-Power Storage-Charging Station Multi-Agent System from the perspective of social welfare maximization. In order to protect the privacies of participants, a distributed interactive algorithm is proposed to solve the coordinated operation strategies. Simulation results show that the proposed coordinated operation model can improve the social welfare significantly, the distributed interactive algorithm can protect the privacies of each participant and solve the operation strategies efficiently.
