Loss Reduction and Voltage Enhancement using Fuzzy Inference System for Electrical Transmission Network

Flexible AC Transmission Systems (FACTS) Controllers are used to increase transmission capacity by damping the power system oscillations and regulating the bus voltage at which the Static Compensator is connected. The focus in this paper is to describe the use of Fuzzy Logic Controller with STATCOM Controllers and compare them in static voltage stability improvements for the damping of the IEEE 14 Bus power system oscillations. A Single line diagram of the IEEE 14 Bus standard system is used in this paper with load assumed to be represented by constant impedance. The size and installation location for load margin improvement and price discussions are addressed. The IEEE 14 Bus is modeled using the elements of Simulink. The effectiveness of the proposed controllers, the improvements in power quality and in voltage profile is demonstrated. In the simulation, the results of the proposed model for the Fuzzy Logic Controller based STATCOM are determined.
