Abstract: Due to the voltage and reactive power controllability and high efficiency of grid connection, the synchronous wind generator became the current development trends. The model of dynamic optimal power flow with synchronous wind generator considering the synchronous wind generator reactive power control style and ramp rate is presented. The border of reactive power of wind farm is calculated and the node voltage of the point of interconnection of wind farm is discussed. The reactive and active power is just related to the wind speed and node voltage, which causes calculation without repeated correction. Based on the synchronous wind generator model, considering the randomness change of wind speed and load, an actual 24-hour’s wind speed and load curve is selected for data simulation and studied on the IEEE-14 and IEEE-118 bus system under the constant voltage or power factor control mode. The modern interior point theory is used to find out the optimal solution, which contributes to the dispatching and operating for wind power, finally providing the optimal power distribution of the wind farm.
