Description
Summary:Power system quality is very much important in present days due to increasing non-linearity in the system. Many compensating devices were developed to improve power quality in the power system. Unified power quality conditioner is one of the FACTS devices that can effectively improve power quality. This paper discusses the integration of distributed generation (DG) to Unified Power Quality Conditioner (UPQC). DG delivers power to system and also stabilizes the DC link capacitor in UPQC. Unit vector control strategy was used to control the UPQC. While transferring active power to the system, DG integration gives stability to power system. Results were given when DG was not integrated to the system and when DG was integrated to the system. Results were also shown if DG was integrated to the system with variable load condition. THDs were shown for source current and load current showing how effective the UPQC works for improving power quality.
