"Output Control Method And Output Control Unit For Wind Power Plant"

Abstract: It is intended to provide an output control method and an output control unit for a wind power plant which is capable of preventing the overloading of a storage battery unit and controlling an optimal overall output of a wind turbine generator and the storage battery unit. The output control method for the wind power plant in which the wind turbine generator and the storage battery unit are connected to a power grid in parallel, includes the steps of: calculating total active power and total reactive power to be supplied to the power grid, and switching an operation mode selectively between: a first operation mode in which the wind turbine generator outputs wind turbine required active power and wind turbine required reactive power that can be outputted by the wind turbine generator and the storage battery unit outputs storage battery required active power and storage battery required reactive power which respectively correspond to a difference between the total active power and the wind turbine required active power and a difference between the total reactive power and the wind turbine required reactive power respectively; and a second operation mode in which the storage battery required active power is maintained and the storage battery required reactive power is reduced while the wind turbine reactive power is increased by an amount of the reduction of the storage battery required reactive power in such a case that apparent power based on the storage battery required active power and the storage battery required reactive power exceeds a setting apparent power of the storage battery unit.
