A fuel cell system comprises an interface configured to receive a user operation toward the fuel cell system, and a controller configured to perform a predetermined process related to a reception stop of the user operation at least during a period from a start to an end of a stop operation of the fuel cell system.

Fuel cell system and equipment management method

A power management system includes a first receiver for receiving information specifying reverse power flow from a base power meter measuring at least the reverse power flow output from a facility to a power grid, a second receiver for receiving information specifying each of individual output powers of two or more adjustment power supplies provided in the facility, and a controller for specifying each of individual reverse power flows of the two or more adjustment power supplies managed as the reverse power flow. The controller specifies individual reverse power flows of the two or more adjustment power supplies, by executing a correction process of correcting a discrepancy between a sum of the individual output powers of the two or more adjustment power supplies and the reverse power flow based on the individual output powers of the two or more adjustment power supplies.

Power management system and power management method

A power management server includes a receiver for receiving, from an upper management server, an adjustment request for requesting a fluctuation adjustment of a frequency of a power grid for each fluctuation cycle of an adjustment target, a transmitter for transmitting, to an adjustment power supply, an adjustment instruction for instructing the fluctuation adjustment of the frequency of the power grid according to the fluctuation cycle of the adjustment target requested by the adjustment request, a management unit for managing a correspondence relationship between the fluctuation cycle of the adjustment target instructed by the adjustment instruction and the adjustment power supply, and a controller for determining an adjustment power supply to which the adjustment instruction is to be transmitted based on the correspondence relationship.

Provided is a cogeneration system that includes a plurality of fuel cell devices capable of supplying heat and power to a heat load and a power load and a control device connected to the fuel cell devices. The control device determines an operation mode on the basis of at least one of a heat demand value and a power demand value. The control device controls a power generation efficiency and a heat recovery efficiency by controlling the fuel cell devices on the basis of the operation mode determined.

Cogeneration system for controlling fuel cell devices based on operation mode

A storage cell is driven more flexibly with respect to the power supply state of a commercial grid. A power control apparatus () connects to a grid, is capable of controlling charging and discharging of a storage cell (), and includes a controller () that performs leveling control to reduce a difference from a power purchase amount, which is established in a power purchase plan, by controlling charging and discharging of the storage cell (). The controller () further performs control, upon acquiring a demand response request issued over a network, to make a comparison between the current amount of stored power in the storage cell () and the necessary amount of stored power for complying with the demand response request and to set a target power for power purchase in the leveling control on the basis of the result of the comparison.
