Design and Control of PV-UPQC Using Variable Leaky LMS Based Algorithm for Power Quality Enhancement

Project Code :TEMAPS539


The Main Objective of this Project is to improve the Power quality of the system using PV-UPQC


The proposed work deals with the multiple power quality (PQ) issues by the proper operation and effective control of photovoltaic (PV) fed unified power quality conditioner (UPQC) by using soft computing technique. Variable leaky least mean square (VLLMS) algorithm is neural network based soft computing technique which provides faster convergence rate without drifting the weight parameter beyond the limit. Here, extraction process of fundamental component for both series and shunt compensators of the UPQC is based on VLLMS algorithm. In this method extraction of reference signals for switching of voltage source converters (VSC) of series and shunt compensators is carried out by updating the weights in an iterative manner. The shunt compensator maintains DC link voltage, compensates reactive power demand of load and mitigates harmonics in the current due to the involvement of non-linear load. The series compensator maintains the voltage level at the load terminal and eliminates distortions in voltage waveform due to sag/swell

and harmonics. The functionality of the proposed system is investigated by using MATLAB/Simulink.
