The purpose of this article is to propose and simulate a simple and applied method without complex and time-consuming calculations to control the voltage and reactive power in distribution network in presence of DG using Fuzzy logic. Moreover, the DG active and reactive power calculation equations proportional to the electric power distribution network includes airlines conductors and will be calculated so that do not lead to the voltage increase in at the point of connection to network. Therefore, in order to prove the equations and correctness of the proposed method simulations were implemented based on, ۳۴ NODE TEST FEEDER IEEE network in ETAP software, and the effects of capacitive structure compensation and DG installed were analyzed in different upload situations in three different scenarios and the best utilization scenario was achieved.
