Title:
OFFSHORE FLOATING PHOTOVOLTAIC ENERGY STORAGE INTEGRATED CHARGING STATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/011571
Kind Code:
A1
Abstract:
The present invention relates to the technical field of offshore photovoltaic power generation, and provides an offshore floating photovoltaic energy storage integrated charging station system and a method. The system comprises a triangular floating body structure and a control unit mounted on the floating body structure; energy storage grooves are formed in the floating body structure, energy storage units are mounted in the energy storage grooves, and photovoltaic power generation units are laid on the energy storage grooves. A storage battery pack in the energy storage grooves in each triangular floating body is one energy storage unit, so that it can be effectively guaranteed that the whole system can still keep normal operation when a single energy storage unit fails, and the energy storage unit can independently supply power to or charge a ship when the photovoltaic power generation unit does not generate power and a state of charge of the energy storage unit is adequate. Droop charging and discharging control modes, a constant-power charging control mode, and a standby mode are used for energy storage unit control, and switching is performed among the four control modes according to system requirements, so that stable operation of the system is guaranteed.
