Abstract

Among the important parameters for the control of electrical power systems is the voltage. Traditionally, the On-Load Tap Changer (OLTC) is the most popular and effective voltage control device in a distribution system. This paper presents an approach for the problem of using OLTC for the voltage regulation of a future distribution system. This problem will be solved by using reactive power compensation using Distribution Unified Power Flow Controllers (D-UPFC) at the DG connected bus. To perform multiple control functions, the D-UPFC may be equipped with several controllers. Simulation results reveal that in the worst scenarios of the test system, the proposed control method is able of maintaining the voltage of the system within the permitted range.
