Due to the randomness， fluctuation， intermittence and poor controllability of wind power， it is not only a network planning issue but also a peak load regulation and frequency control problem in the wind farm grid integration. Considering the randomness of wind power， a generation planning is proposed， in which the proper regulating units are determined as complement to the wind power. Based on that， a combination of site selection of regulating units and transmission network planning method model associated with wind power integration is built. IEEE-RTS is used as a test system to prove the validity of the proposed model.
