Voltage Sag Enhancement of Grid Connected Hybrid PV-Wind Power System Using Battery and SMES Based Dynamic Voltage Restorer

Also Available Domains Hybrid Systems|Power Quality

Project Code :TEPGPS146


Main objective of this project is to reduce the voltage fluctuation, Compensating Symmetrical and asymmetrical voltage sags in the system.


In this project, to withstand and secure the effect of voltage fluctuation of grid connected hybrid, PV-wind power system Dynamic Voltage Restorer (DVR) is proposed. battery and Super Magnetic Energy Storage (SMES) based DVR is used as a compensating device in case of voltage sag condition. 

The compensation method used is a pre-sag compensation which locks the instantaneous real time three phase voltage magnitude and angle in normal condition at the Point of Common Coupling (PCC) and stores independently so that during a disturbance it used for compensation. Symmetrical and asymmetrical voltage sags scenario are considered and compensation is carried out using MATLAB/SIMULINK software.

Keywords: Dynamic voltage restorer (DVR), energy storage, intermittent, power quality, voltage sag compensation.
