This project is an integrated PV-storage-charging warehouse project based on the construction of regional material warehouse of China Southern Power Grid. The project combines the roof PV power generation system, the energy storage system, the DC lighting and the fast charging device of electric vehicles in the power regional warehouse park to form an integrated PV-storage-charging system. In this project, CYG has provided a perfect AC/DC microgrid integrated solution and all the equipment in the microgrid. After the completion of the project, the loads can be driven by PV, power grid and energy storage, and multi-energy complementation and collaborative supply can be realized, so as to meet the normal power supply of the park in the on-grid and off-grid modes, and improve the power consumption economy and reliability of the park.
