A power management system for managing at least one power generation system connected to an electrical grid and at least one energy storage device connected to the electrical grid, wherein the energy storage device is charged or discharged in a time period in which the reliability of the prediction of the amount of power generation and the power demand per time period is high based on a predicted amount of power generation which is an amount of power generation of the power generation system predicted for each time period and a predicted power demand which is a power demand for the electrical grid. Thus, more proper energy management can be performed.

Power management system

An electric power management system includes a plurality of the vehicles, each including a battery, and a server that manages an exchange of electric power between the battery and an electric power system of an electric power company. The server detects a predetermined operation of a user that correlates with termination of the exchange of the electric power between the battery and the electric power system. When the predetermined operation is detected, the server calculates an estimated time when the exchange of the electric power between the battery and the electric power system is terminated, and executes a process of distributing the electric power to be exchanged by the vehicle in which the exchange of the electric power with the electric power system is estimated to be terminated at the calculated estimated time to another vehicle that performs the exchange of the electric power with the electric power system.

A control system includes a computer that controls each of multiple power balancing resources. The computer selects one or more control targets to be used for power balancing of an external electric power source from the power balancing resources, and controls each of the one or more control targets so as to cause the power storage device to charge or discharge for the power balancing. The computer preferentially selects the power balancing resource provided with a small-capacity power storage device as the control target for the power balancing of which duration is shorter than a predetermined time, and preferentially selects the power balancing resource provided with a large-capacity power storage device as the control target for the power balancing of which the duration is longer than the predetermined time.

A charge and discharge control device includes a controller configured to: predict, for each of vehicles included in a vehicle group, a remaining capacity of a storage battery mounted on each of the vehicles within a future predetermined period using a behavior prediction model that predicts behavior of each of the vehicle; optimize, for each vehicle, an instruction value of a charge and discharge power amount of the storage battery within the predetermined period such that an accumulation value of the charge and discharge power amounts follows a demand value for the vehicle group while minimizing a degradation amount of the storage battery using the predicted remaining capacities of the storage batteries and a battery degradation prediction model that predicts the degradation amount of the storage battery from the remaining capacity; and control a charging and discharging operation of the storage battery according to the optimized instruction value.

Charge and discharge control device

An electric power management system is a system that performs an exchange of electric power with an electric power system of an electric power company that is a counterparty of the exchange of the electric power, and includes a plurality of the vehicles, each including a battery, and a server that manages an exchange of the electric power between the battery of each of the vehicles and the electric power system. The server manages the exchange of the electric power for each vehicle group in which the vehicles are bundled, and configures the vehicle groups in advance such that distributions of the electric power supply and demand characteristics of the batteries of the vehicles included in the vehicle groups are the same or similar.

A control system includes a computer configured to remotely control at least one of charging and discharging of a power storage device mounted on a control target. The computer is configured to transmit a first command indicating charging power or discharging power of the power storage device to the control target via each of a first communication path and a second communication path. The control system further includes a determination unit configured to determine whether or not any one of the first communication path and the second communication path is under a cyberattack by using a second command received by the control target via the first communication path when the computer transmits the first command, and a third command received by the control target via the second communication path when the computer transmits the first command.

An electric power system includes a plurality of power adjustment resources electrically connectable to a power grid, and a management device configured to manage the power adjustment resources. The management device is configured to acquire a first request signal for requesting demand-and-supply adjustment in the power grid, and a second request signal for requesting the power adjustment resources to adjust electric energy in a predetermined period, transmit a power command signal indicating a command power value for each predetermined interval in the predetermined period to a predetermined power adjustment resource included in the power adjustment resources, and generate the power command signal to respond to both requests of the first request signal and the second request signal.
