Storage battery output power control method for wind turbine generator

摘要

A control method for a wind turbine generator and storage battery unit connected to a power grid in parallel, includes calculating total active power and total reactive power, and switching between: a first mode in which the generator outputs turbine required active power and reactive power that can be outputted by the generator and the battery unit outputs battery required active power and battery required reactive power which correspond to a difference between the total active power and the turbine required active power and a difference between the total reactive power and the turbine required reactive power respectively; and a second mode in which the battery required active power is maintained and the battery required reactive power is reduced while the turbine reactive power is increased by an amount of the reduction of the battery required reactive power wherein apparent power exceeds a set battery unit apparent power.
