Expansion of research on communication network and system control technology suitable for photovoltaic storage and charging station. Based on G3_PLC technology, communication network suitable for the system control requirements of photovoltaic storage and charging station is studied. The hardware implementation of communication terminal is given. The characteristics of high-speed transmission of communication network and adaptive mesh network topology are analyzed. At the same time, combined with the communication network architecture, the centralized MAS technology is introduced into the corresponding communication terminals, and the control strategy based on it is given. The information exchange between different agents is realized through the power line in the photovoltaic storage and charging station system. By building a communication network to verify the transmission performance of the communication network, it is concluded that the communication rate can reach 60 KBS under the appropriate routing parameters. The centralized MAS control strategy studied can achieve active energy utilization by utilizing photovoltaic power generation and battery charging and discharging energy to achieve the balance of power flow in the photovoltaic storage and charging station.
