In order to operate wind power generation efficiently， this paper presents a novel method to allocate active loads in distribution systems based on the current wind power grid codes. The method uses feeder terminals（FTs） as basic control units. When there is deviation in the system frequency， each FT determines how to allocate loads and send dispatch commands to all wind farms connected to it. This method not only considers“Law for Renewable Energy in People's Republic of China” and economic interests of different wind farm developers， but also the system frequency and wind farm capacity in dispatching the active loads. In addition， it can dispatch active loads either according to the wind farms capacities or the power flows in different feeders， depending on the system automation level. Both schemes are satisfactory in meeting the system operation demands well. A case study indicates the feasibility and practicability of the proposed method.
