Experimental validation of solar PV sustained ZSI based unified active power filter for enrichment of power quality

The deployment of power electronic devices has become a big concern for quality in these days. voltage stabilization distribution networks interconnected with Photo Voltaic (PV) is very critical promoting the smooth operation all linked system. Voltage profile maintenance one challenges PV integration into grid. Conventional such as passive filters, series and shunt synchronous condensers, etc. are insufficient to alleviate numerous problems quality. compensator used current Also, if two simultaneously mitigated, device system known Unified Active Power Filter (UAPF). UAPF equipped Z-source inverter(ZSI). This paper addresses associated existing concerns which including sag, swell, distortion simulates problems. Unit Vector Template Generation (UVTG) Improved Second Order Generalized Integrator (ISOGI) based Phase Locked Loop (PLL) utilized controller simulation experimental results validated proposed work.
