METHOD FOR OPERATING A WIND FARM, WIND FARM CONTROLLER AND WIND FARM

摘要

PURPOSE: A method for operating a wind power plant, a wind power plant controller, and a wind power plant are provided to extend the life of a wind turbine by reducing loads put on the wind turbine. CONSTITUTION: A wind power plant(24) includes wind turbines(25-28) and an energy storage device(46). The wind power plant is connected to an external grid. Required active power is determined. Required reactive power is determined. Power production of the wind turbines is determined. When the power production exceeds the required active power, the required reactive power, or a vector sum of the required active power and the required reactive power, the energy storage device is charged.
