A plurality of storage battery modules include storage battery control devices that can mutually communicate with each other and obtain a demand for electric power in a predetermined consumer in which the plurality of storage battery modules are provided. The storage battery control devices mutually transmit and receive charging/discharging electric power of the storage batteries and control charging/discharging of the plurality of storage battery modules, respectively, on the basis of the demand for electric power in the predetermined consumer.

Storage battery control device and storage battery control method

A storage battery control system comprises multiple storage batteries disposed in a power grid, and a storage battery control apparatus. The storage battery control apparatus is communicably coupled to the multiple storage batteries and an energy management system. The storage battery control apparatus acquires storage battery information comprising a charging-discharging performance and a remaining capacity from each of the storage batteries, acquires power supply-demand prediction information showing a prediction of power supply and demand in a prescribed range from the energy management system, decides an individual charging-discharging rate for each of the storage batteries based on the storage battery information and the power supply-demand prediction information, and sends the decided individual charging-discharging rate to each of the storage batteries. Each of the storage batteries operates based on the individual charging-discharging rate received from the storage battery control apparatus.

Storage battery control system and storage battery control method

Electric-power management system, an area controller transmits, to each of section controllers, information about a target voltage and information about the present voltage, each of the section controllers calculating a difference between the target voltage and the present voltage, received from the area controller, and calculating a power's demand-supply-adjustment request amount based on difference between the information about the voltages, each of facility-equipment controllers transmitting power-reception/power-release capable equipment information to each section controller, being information about a power-reception/power-release capable equipment in a facility into which the facility-equipment controller is installed, the section controller, based on the power-reception/power-release capable equipment information about the equipment, transmitting the equipment's demand-supply-adjustment request amount and the facility-equipment controller transmitting a control signal to the equipment based on the equipment's demand-supply-adjustment request amount received from the section controller to the facility-equipment controller in the facility.

Electric-power management system, electric-power management method, and section controller

The system control apparatus for equipment for causing equipment to collaboratively operate includes: equipment profile management means for managing an equipment profile that is metadata representing the electrical properties of the equipment; control scenario management means for managing a control scenario in which is described metadata that states an operation to be fulfilled by the equipment; equipment detection means for detecting control-targeted equipment; electrical status monitoring means for monitoring an electrical status related to transfer of electrical power caused by equipment interconnections; equipment selection means for selecting equipment for use on the basis of the metadata described in the control scenario and the equipment profile; and control execution means for controlling the selected equipment.
