  • POWER CONTROL APPARATUS AND POWER CONTROL METHOD
    Publication number: 20220337067
    Abstract: A power control apparatus of an embodiment controls power to be output to a power system from a power station including a power generation unit, and a power storage unit. The power control apparatus includes a power generation control unit, a power storage control unit, and a cooperation control unit. The power generation control unit controls an output of the power generation unit based on a power generation set value. The power storage control unit controls an output of the power storage unit based on a power storage set value. The cooperation control unit outputs the power generation set value to the power generation control unit and outputs the power storage set value to the power storage control unit based on a power demand amount of the power system so as to make the power generation unit and the power storage unit operate in a cooperative manner.
