Coordinative distribution strategy of wind farm output active power

Usually,the wind farm power is equally distributed to units without considering their operating conditions.Four types of wind turbine are classified according to its power output and operating state: critical power output,reduced power output,low wind speed and high wind speed,based on which,an output power distribution strategy of coordinative pitch and speed control is proposed for wind farm.It considers the difference between wind turbines and optimizes the output power distribution in economy and safety.Result of simulation with Simulink shows that,the proposed coordinative distribution strategy realizes the coordination and optimization of wind farm output power distribution.
