Abstract:
The rapid technological development all around the world roots huge demand for power. This
in turn leads to increased utilization of fossil fuels for power generation. Hence, global warming becomes
high and in turn affects the environmental condition. So now a days, a numerous Renewable Energy
Sources (RES) such as Solar, Biomass, wind etc., comes into existence. Among the various Renewable
Energy Sources (RES), solar energy plays a vital role in power generation. While instigating this solar
energy into a grid, various power quality complications such as voltage sag, voltage flicker, transient and
harmonics occurs. Hence in order to overcome these complications, Dynamic Voltage Restorer (DVR)
affords a best solution. Henceforth, this work proposes a Multi-level inverter based DVR system for
enhancement of power quality. Apart from this, it also investigates the performance of the proposed DVR
with both conventional and artificial intelligent controller. It implements a PSO based MPPT technique to
track maximum power from the solar system. From the results, it is concluded that the proposed DVR
with neural controller provides the best results and the Total Harmonic Distortion (THD) of the proposed
technique odeys the IEEE standards.
