Abstract
An electric power control system includes electric vehicles and a facility. The facility includes chargers and a server. The server includes processing circuitry. The processing circuitry controls charging and discharging operations of each charger. The processing circuitry executes a predicting process for predicting electric power demands of the facility in specified time periods, and when any one of the predicted electric power demands is greater than a predetermined specified value, a requesting process for issuing a connection request requesting for the electric vehicles that is capable of supplying the facility with electric power to be connected to the chargers.
Claims20
An electric power control system, comprising:
- electric vehicles, each provided with a battery that is chargeable and dischargeable;
- and
- a facility configured to draw electric power, wherein:
- the facility includes
- power-receiving equipment configured to be supplied with electric power from an electric power grid,
- chargers, each of which is electrically connected to the power-receiving equipment and each of which selectively performs one of a charging operation and a discharging operation in a state electrically connected to one of the electric vehicles, the charging operation causing the power receiving equipment to supply electric power to the electrically connected electric vehicle, and the discharging operation causing the electrically connected electric vehicle to supply electric power to the facility, and
- a server provided with processing circuitry configured to control the charging operation and the discharging operation of each of the chargers;
- and
- the processing circuitry is configured to execute a predicting process that predicts electric power demands, in which each of the electric power demands is the electric power drawn by the facility in a corresponding one of specified time periods, and
- when any one of the predicted electric power demands is greater than a predetermined specified value, the processing circuitry is configured to execute a requesting process that issues a connection request requesting for any of the electric vehicles that is capable of supplying the facility with electric power to be connected to one of the chargers.
A method for controlling electric power in an electric power control system, the electric power control system including electric vehicles, each provided with a battery that is chargeable and dischargeable, and a facility configured to draw electric power, in which the facility includes power-receiving equipment configured to be supplied with electric power from an electric power grid, chargers, each of which is electrically connected to the power-receiving equipment and each of which selectively performs one of a charging operation and a discharging operation in a state electrically connected to one of the electric vehicles, the charging operation causing the power receiving equipment to supply electric power to the electrically connected electric vehicle, and the discharging operation causing the electrically connected electric vehicle to supply electric power to the facility, and a server provided with processing circuitry configured to control the charging operation and the discharging operation of each of the chargers, the method comprising:
- executing a predicting process that predicts electric power demands with the processing circuitry, in which each of the electric power demands is the electric power drawn by the facility in a corresponding one of specified time periods, and
- when any one of the predicted electric power demands is greater than a predetermined specified value, executing a requesting process with the processing circuitry that issues a connection request requesting for any of the electric vehicles that is capable of supplying the facility with electric power to be connected to one of the chargers.
A non-transitory computer-readable medium storing an electric power control program for an electric power control system, the electric power control system including electric vehicles, each provided with a battery that is chargeable and dischargeable, and a facility configured to draw electric power, in which the facility includes power-receiving equipment configured to be supplied with electric power from an electric power grid, chargers, each of which is electrically connected to the power-receiving equipment and each of which selectively performs one of a charging operation and a discharging operation in a state electrically connected to one of the electric vehicles, the charging operation causing the power receiving equipment to supply electric power to the electrically connected electric vehicle, and the discharging operation causing the electrically connected electric vehicle to supply electric power to the facility, and a server provided with processing circuitry configured to control the charging operation and the discharging operation of each of the chargers, the electric control program, when executed by the processing circuitry, causing the processing circuitry to execute:
- a predicting process that predicts electric power demands, in which each of the electric power demands is the electric power drawn by the facility in a corresponding one of specified time periods, and
- when any one of the predicted electric power demands is greater than a predetermined specified value, a requesting process that issues a connection request requesting for any of the electric vehicles that is capable of supplying the facility with electric power to be connected to one of the chargers.
