Abstract
In this paper, the power quality (PQ) profile like harmonics and voltage sag is improved in the power system by integrating a solar PV-based unified power quality conditioner (UPQC). The control technique of the UPQC is designed by using a basic a synchronous reference frame technique for reference current generation, hysteresis current controller technique for switching pulse generation and conventional proportional- and integral- (PI)based DC-link voltage controller. The foremost objective of the proposed research is to control the DC-link voltage of the UPQC which is achieved by integrating a solar PV-based renewable energy source across its DC-link capacitor. The analysis is carried using MATLAB simulated results. To verify the outcomes, the proposed UPQC results are also compared with conventional PI controller.
