Title:
POWER SUPPLY SYSTEM AND STORAGE POWER CONDITIONER
Document Type and Number:
Japanese Patent JP2023073202
Kind Code:
A
Abstract:
To suppress and stabilize voltage fluctuations when a power generation system and a storage battery system are interconnected to supply power to a load during stand-alone operation.SOLUTION: A power supply system includes a power generation system and a storage battery system and is interconnected with a power grid and supplies power to a load. The power supply system is capable of supplying first AC power generated from power generated by the power generation system and second AC power generated from power stored in the storage battery system to the load during stand-alone operation. The power generation system is connected to the storage battery system via a power feeding path to which the load is connected and outputs the first AC power that is interconnected with the voltage of the second AC power output from the storage battery system to the power feeding path. The storage battery system acquires a physical quantity that affects the variation of the first AC power output from the power generation system to the power feeding path, operates the duty ratio so that the voltage of the second AC power does not fluctuate in accordance with the acquired physical quantity, and maintains the frequency of the AC voltage supplied to the power feeding path at a constant level.SELECTED DRAWING: Figure 4
