Method and device for distributing active power for wind power generation zones

摘要

A method and device for distributing active power for a wind farm is provided. The method includes calculating a current total active power deviation of a wind farm according to a current frequency deviation of a power grid; Unit storage energy value of each wind turbine and the current total active power deviation if the current total active power deviation of the wind turbine is greater than zero, - distributing a unit active power deviation; In accordance with a first predetermined strategy based on the degradable power value of each wind turbine in the wind power generation plant and the current total active power deviation, if the current total active power deviation of the wind farm is less than zero, Distributing a single-unit active power deviation; And controlling each wind turbine to adjust its operating state in accordance with the current distributed single-unit active power deviation. Thus, the modified active power value of each wind turbine in the wind power generation area is as uniform as possible, thereby reducing the impact on the wind turbine during frequency modulation control.
