  • Patent number: 8332077
    Abstract: In a controller for a windfarm including a plurality of wind turbine generators controllable in rotation frequency and pith of blades of the wind turbine generators, coupled to a grid through a transmission line, an anemometer is provided to each wind turbine generator to transmits wind direction and wind speed data to a central controller which process the wind direction and wind speed data to transmit an output command each wind turbine generator. The central controller predicts, on the basis of the wind speed detected by the upstream wind turbine generator, variation in wind speed at other wind turbine generators to control the output of the windfarm. The output power may be limited or charging energy as rotation energy of blades and discharging the rotation energy as output power in addition to a battery unit for averaging.

  • Publication number: 20120068660
    Abstract: A battery-used power grid operation method for handling a home-use secondary battery as a virtual battery of medium- to large-scale and for lessening a necessary cell capacity to thereby enable efficient absorption of an output variation of renewable energy-derived electric power is provided. In a power system including electrical household appliances in a house having a renewable power generator, an individual house-installed rechargeable battery or separately central-managed battery, and a control device which measures and controls an output variation of the renewable power generator, those output variations of the renewable power generator occurring with time and due to changes of weather and seasons are absorbed as much as possible by preset-temperature control of the electric household appliances in the house while absorbing the remaining variations by charge/discharge of the battery, thereby lessening an electricity storage capacity required for the variation absorption.

  • Patent number: 8103846
    Abstract: A memory management unit for an information processing system includes a controller and a non-volatile memory. The controller controls data writing process. The non-volatile memory, used for storing non-rewritable and rewritable data, is partitioned into a read-only partition to store the non-rewritable data, and a rewritable partition to store the rewritable data including apparatus-specific data including access-restricted data required for activating the information processing system. The access-restricted data is prohibited from being written during normal usage but writable at specific times. The non-rewritable data, stored in the read-only partition, is protected from an abrupt power shutdown occurring when a data writing process is conducted to the rewritable data. The controller stores the access-restricted data to the read-only partition by changing an attribute of the read-only partition of the non-volatile memory from a read-only attribute to a rewritable attribute.
