Development of Communication Systems for a Photovoltaic
Power-drop smoothing scenario. Equipment of the PV/BESS with ASC plant: a) BESS, inverter and smart sensor, b) ASC and PV panels, c) ASC communication system and d) weather
The requirements of the communication systems were defined based on the applications that control the PV plant, and on the industry-standard IEC-61724-1 norm for PV data. After being developed, the communication systems were installed in a PV plant, and the interaction between the data obtained from these two systems is discussed and presented.
In small residential or commercial PV plants, it is practical to use the site's existing Ethernet network for data transmission, as demonstrated in . However, in larger centralized PV systems, it is advisable to install a dedicated transmission network for data, as shown in .
A PV/BESS plant has been installed at UFPB, featuring a PV array with a peak power of 10.07 kWp and a BESS with a power rating of 5 kW and a capacity of 10 kWh. The CS was designed with scalability in mind, allowing for future expansion and implementation in larger utility-scale power plants.
Type and source of data: all real-time data from the PV/BESS plant. Modbus is an asynchronous communication protocol in which data are sent by the server only when requested by the client . Despite its age, the protocol is still widely used mainly due to its open license.
