ResearchSubjectsWind Power TeamIt is essential to reduce power generation costs in order to accelerate the use of wind power generation. To achieve this, sophistication of software aspects including proper siting, eval-uation of annual energy production, and forecasting of power generation during operation are required, in addition to improvement of wind turbine hardware.High-Performance Wind Power Generationby “Foreseeing Wind Conditions”●Establishment of measurement/evaluation technology 　using a nacelle-mounted LIDAR (laser anemometer)●Improvement of wind turbine power output and reliability/lifetime through the 　development of feed-forward control●Establishment of evaluation technology for more accurate prediction/forecasting 　of available resources, power generation, noise, etc.To demonstrate the effectiveness of the elemental technologies for the next-generation wind turbines, the team launched real-time remote measurement/evaluation of wind data on the upwind side of a wind turbine by means of a nacelle-mounted LIDAR. The results are being used to establish control technologies for upgrading the wind turbine performance (higher availability and capacity factor, improved reliability and lifetime).As a new alternative technology to high-cost in-situ wind measurements on the offshore, the team is developing a technology for evaluating offshore wind conditions using satellite remote sensing and numerical meteorological models to improve the accuracy and resolution of eval-uated offshore wind conditions.Smart System Research FacilityThe Smart System Research Facility was built to enhance the functions of the world’s electric power systems in preparation for the age of renewable energy. The facility has the world’s most advanced power supply equip-ment, anechoic chamber and environmental test laboratory for research, development and testing of inverters for PV power generation and power storage systems.Energy ManagementBuildingOrganizationOrganizationDirector-GeneralSupervisory Innovation CoordinatorInnovation CoordinatorDeputy Director-GeneralGeneral Affairs OfficeCollaboration Affairs OfficeDER Facility Operating OfficePrincipal Research ManagerDeputy DirectorJoint Appointed FellowDirectorResearch TeamsHydrogenEnergyCarrierTeamWindPowerTeamPhotovoltaicPowerTeamGeothermalEnergyTeamShallowGeothermal andHydrogeologyTeamEnergyNetworkTeamFurther Cost Reduction and Eciency Improvementof Renewable Energy2ThemeResearch wind turbine (Komaihaltec, Inc.
