Research on Access Scheme for Distributed Photovoltaic Cluster Based on Wireless Communication

China is comprehensively launching the planning and construction of large-scale photovoltaic (PV) bases, accelerating the integration of power generation, grid, and energy storage, as well as the integration of wind and solar power for hydrogen production. However, as the installed capacity continues to increase, higher demands are placed on the construction and operation maintenance of PV power plants. The communication network of PV power plants serves as the nerve center of the entire system, responsible for transmitting measurement and control information and providing feedback on fault status. It also supports various power-related operations. In this context, designing an optimal communication scheme for PV power plants not only ensures accurate real-time monitoring of the plant’s status but also guarantees its safe and reliable operation. Furthermore, it provides a scientific basis for decision-making regarding power generation efficiency, fault prediction, and risk control. This paper investigates the networking scheme of wireless transmission technology in the context of PV scenarios. We presents the design of micro-gateways and the secure access scheme for the network.
