  • Power system stabilizer
    Patent number: 9640999
    Abstract: A technique with which a change in power frequency can be suppressed. A power system stabilizer issues a control command to a first storage battery among a plurality of first power generators and the first storage battery that are connected to an isolated island system via a first tie-line. The power system stabilizer includes a parameter determination unit and a control block unit. The parameter determination unit obtains, on the basis of operation information, a rate-of-change limit value that indicates a limit to be imposed on a total value of changes in the overall output of first power generators in operation. The control block unit generates a command value to be given to the first storage battery on the basis of an interconnection point power flow value measured on the first tie-line and the rate-of-change limit value obtained by the parameter determination unit.

  • Automated system for power retailing
    Publication number: 20020194012
    Abstract: Transaction of electric power has been conventionally conducted mainly to cope with power demand of a large-volume customer, and in which a power customer presents a power demand for covering a certain period of time, and power companies tenders for the offer. In this manner, the transaction was done in reliance on manpower.
