Abstract- Modern power system comprises of complex networks where many generating stations and load centres are interconnected through long power transmission and distribution networks. Utility distribution networks critical commercial operations and sensitive industrial loads all suffer from various types of outages and interruptions which can lead to significant financial loss loss of production idle work forces etc. Today due the changing trends and restructuring of power systems the consumers are looking forward to the quality and reliability of power supply at the load centres. A power quality problem is an occurrence manifested as a nonstandard voltage current or frequency that results in a failure or a mis-operation of end use equipments. With shifting trend towards distributed and dispersed generation the issue of power quality is taking new dimensions. The present investigates PID controller and fuzzy logic controller as concerned to UPQC application for power quality improvement. The UPQC is studied and its advantages over conventional APFs and UPQC are discussed in detail. The relevant mathematical models and equations to explain the working of UPQC are derived for both the cases PID controller and fuzzy logic controller.The relevant simulations are carried out using MATLAB Simulink.
