Provided are a power control apparatus, a power supply system, and a method for controlling a power supply system that can reduce the power loss when charging a storage battery from a power generation apparatus. A power control apparatus (power conditioner) controls connection between a storage battery and a power generation apparatus and includes a controller capable of selecting between a first electrical path in which the storage battery is connected to an inverter via a first power converter and the power generation apparatus is connected to the inverter via a second power converter, and a second electrical path in which the power generation apparatus is connected to the inverter via the second power converter and the storage battery is connected to an intermediate point between the power generation apparatus and the second power converter via the first power converter. When surplus power is generated from the power generation apparatus, the controller selects the second electrical path and charges the storage battery with the surplus power.
A power control apparatus for controlling connection between a storage battery and a power generation apparatus generating DC power, the power control apparatus comprising:
A power supply system comprising a storage battery, a power generation apparatus generating DC power, and a power control apparatus configured to control connection between the storage battery and the power generation apparatus;
A method for controlling a power supply system, the power supply system comprising a storage battery, a power generation apparatus generating DC power, an inverter, a first power converter between the storage battery and the inverter, a second power converter between the power generation apparatus and the inverter, a switch on a side of the first power converter that is opposite the storage battery, wherein the switch is configured to switch between a first electrical path which connects to a first side of the second power converter between the second power converter and the inverter, such that the power generation apparatus is connected to the storage battery via both the first power converter and the second power converter, and a second electrical path which connects to a second side of the second power converter between the power generation apparatus and the second power converter, such that the power generation apparatus is connected to the storage battery via the first power converter but not the second power converter, the method comprising, by a controller, when surplus power is generated from the power generation apparatus:
A method for controlling a power supply system, the power supply system comprising a storage battery, a power generation apparatus generating DC power, and a power control apparatus configured to control connection between the storage battery and the power generation apparatus,
