Improved Performance Analysis and Reactive Power Compensation of FACTS Devices Utilizing Fuzzy Logic

In most cases, a STATCOM is utilized to provide support for electrical networks in the event that as a result, the network's power factor decreases and voltage regulation issues become chronic. Because the STATCOM relies on a voltage source converter (VSC), its power supply must be behind a reactor. Adding a suitable energy storage device across the DC capacitor can improve the active power capabilities. This will allow for increased power output. The amount of reactive power present at the STATCOM terminals depends on how much power is supplied. When compared to an SVC, a STATCOM has a quicker response time. This is mostly because to the rapid switching speeds made possible by the voltage source converter's switches, which results in a shorter response time. In addition, compared to an SVC, the STATCOM provides improved support for reactive power even at low AC voltages. On the other hand, these devices can only provide shunt compensation. This research study suggests a novel technique centered on the reduction of line losses in loop distribution systems as a means of overcoming this restriction. The Unified Power Flow Controller, often known as the UPFC, is applied in order to experimentally accomplish these conditions of lowest loss. In contrast to the STATCOM, the UPFC can do series and shunt compensation, which enables the user to exercise control over both voltage and current. To meet this goal, this research developed a fuzzy logic controller-based implementation of a STATCOM and UPFC for reactive power compensation in distribution networks.
