Assignee: KABUSHIKI KAISHA TOSHIBA
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A power system, comprising:
a power output apparatus configured to generate, based on input power from one of an electrical grid and a power storage, output power to another of the electrical grid and the power storage;
a control apparatus configured to control the power output apparatus, wherein the control apparatus comprises:
a communicator configured to receive a grid frequency of the electrical grid and a state of charge of the power storage, or information allowing the grid frequency and the state of charge to be calculated; and
a processor configured to determine an output destination and an output rate of the output power, from the grid frequency, based on a predetermined function of calculating the output destination and the output rate depending on when the grid frequency,
wherein
when the communicator receives instruction regarding the output destination and the output rate of the output power from the electrical grid, the processor determines the output destination and the output rate of the output power following the instruction,
when the communicator receives a notification of permitting determination of the output destination and the output rate of the output power from the electrical grid or in a predetermined time slot, the processor determines the output destination and the output rate adjusted according to the state of charge, by changing the function, and
the power output apparatus receives the input power from one of the electrical grid and the power storage that is determined not to be the output destination, generates the output power based on the input power, and outputs the output power to the output destination determined by the control apparatus, at a rate as high as the output rate determined by the control apparatus.
