Abstarct: Nowadays, power quality improvement has become one of the most important issues in electrical power distribution networks that the main reason for which is the increasing use of equipment-baxsed power electronics, which is non-linear in nature. One of the best ways to compensate for power quality issues is to use a unified power quality conditioner (UPQC) that has the ability to simultaneously compensate for power quality issues related to voltage and current, which are divided into two general structures: voltage source and current source. In this research, the current type of this compensator has been designed and simulated. The advantages of this structure include inherent protection against possible short circuit due to the presence of a dc inductor and fast response to voltage distortion due to the presence of only one first-order filter. Compensation for voltage sag and swell, voltage unbalance, and harmonic is carried out by the proposed model and researched using MATLAB / SIMUlixnk software for three different loads. The used control algorithms are baxsed on synchronous reference frxame theory, instantaneous power theory (p-q) and hysteresis band current controller. The results show 80% voltage sag compensation and full voltage swell compensation. As well as, the voltage unbalance and the harmonic amount of the load current are significantly reduced. Harmonic spectrum analysis was performed for load voltage and source current and the results show a decrease in source current harmonics from 15.83% to 1.38% and total harmonic distortion for load voltage to 1.12%.
