Offshore floating light energy storage integrated charging station system and operation control method thereof

An offshore floating light energy storage integrated charging station system, comprising:

• a triangular floating floater structure;
• a control unit;
• an energy storage unit;
• and
• a photovoltaic electricity generation unit,
• wherein an energy storage tank is arranged on the floating floater structure, the energy storage unit is mounted in the energy storage tank, and the photovoltaic electricity generation unit is paved on the energy storage tank;
• the photovoltaic electricity generation unit is used for converting light energy into electrical energy;
• the energy storage unit is used for storing excess electrical energy generated by the photovoltaic electricity generation unit, and providing a differential power when a power of the photovoltaic electricity generation unit is less than a load demand power;
• and
• the control unit is used for controlling an operation mode of the system based on an illumination intensity ill, a state of charge (SOC) of the energy storage unit, a DC bus voltage Udc and a presence or an absence of a load on a charging interface.
