  • Publication number: 20240128755
    Abstract: An energy storage system according to an embodiment includes first and second power storage devices and performs charge/discharge control for the power storage devices based on a charge/discharge command value. The first power storage device performs discharging for one or more devices as destination via a power line or performs charging of power supplied from one or more devices as source via the power line, and the second power storage device performs charging and discharging for the first power storage device. The energy storage system also includes a control system that controls charge/discharge power of the second power storage device so that a power storage rate of the first power storage device falls within a predetermined power storage rate range and controls charge/discharge power of the first power storage device based on charge/discharge power corresponding to the charge/discharge command value and the charge/discharge power of the second power storage device.

  • Publication number: 20230223757
    Abstract: A power storage control system includes a storage battery and a controller. The storage battery supplies electric power to an electric power system in collaboration with a power generator in response to a command value. The controller outputs, to the power generator, a stop signal causing the power generator to stop power generation when a state of charge of the storage battery is larger than a given value. The controller outputs, to the power generator, an execution signal causing the power generator to execute power generation when the state of charge is not larger than the given value. The controller acquires an actual electric power value generated by the power generator. The controller outputs a control signal causing the storage battery to execute charging and discharging for satisfying the command value on the basis of a difference between the command value and the actual electric power value.

  • Patent number: 9152341
    Abstract: According to one embodiment, a storage controller includes a dividing unit, a duplication manager, and a duplication determination unit. The dividing unit divides data specified in a write request from a host computer into a plurality of chunks. The duplication manager preferentially stores a first hash value of a first chunk in a first table in a hash table in association with the first chunk when the first chunk is written to a storage device. The hash table includes a second table having more entries than the first table. The duplication determination unit first searches the first table for a third hash value matching a second hash value of a second chunk when the second hash value has been calculated.

  • Publication number: 20100161745
    Abstract: According to one embodiment, there is provided a communication system includes endpoints and server units. The endpoints include a transmitter and an information assignment module. The transmitter transmits a message of the registration request to one of the server units. The information assignment module assigns information used to discriminate a cause of generation of the registration request to the message. The server units include a specification module, a determination module and a registration processor. The specification module specifies the cause based on the information assigned to the received message. The determination module determines whether or not permit registration of the endpoint as a source of the received message based on the specified cause and priority level. The registration processor registers the endpoint when the registration is permitted. The registration processor instructs the endpoint to redirect the message when the registration is not permitted.

  • Publication number: 20090168771
    Abstract: According to one embodiment, if the message makes a round in accordance with the order put to the IPTs in advance, the main unit recognizes that all the IPTs are connected to the LAN. If the end message comes back to the main unit for the start message transmitted from the main unit, all the IPTs are present on the LAN. The IPTs mutually perform the keep-alive processing among terminals in turn. In the process, if timeout occurs, the IPT which has detected the occurrence notifies the absence of the next IPT to the main unit, and change the order of the keep-alive processing.
