    The problem of large power loss rate exists both in the design of distribution network route structure and in the layout of outlets. In order to reduce the power loss of the distribution network and continuously improve its power quality, the active power adjustment method of distribution network group-controlled station area based on Automatic Voltage Control(AVC) technology is studied. Based on the equivalent load of distribution network line operation, the unbalanced power component of distribution network group-controlled station area is defined; the negative sequence component and positive sequence component are divided according to the dynamic command corresponding to the operation mode, and the power regulation function of distribution network group-controlled station area is determined under different differential gain conditions; according to the regulation function and the ranges of the different parameters, the regulation mode is determined based on the AVC technology, and the power quality of distribution network group-controlled station area is improved by AVC technology. According to the regulation function and the range of different parameters, the regulation mode is determined based on AVC technology to actively regulate the unbalanced power of distribution network group-controlled stations, and the method design is completed. Taking several public stations in the distribution network as the test object, and by adjusting the reactive power compensation capacity of each group of stations, the compensation capacity can reach up to 580 kVA. It indicates that the proposed method can realize the active regulation of the power capacity, meeting the operational standards of distribution network lines and demonstrating practical application value.
