Harmonic Mitigation in Grid connected PV using Shunt Active Filter

Harmonic mitigation in PV grid using Shunt Active Filters is a promising approach to improving the safety and stability of photovoltaic systems, albeit with some caveats. By actively filtering harmonics from both the AC source and DC side, shunt filters enable improved voltage regulation, efficient power factor correction, wider dynamic range input current control, suppressing transients to ensure system reliability and reducing audible noise caused by harmonic distortion. It also increases power system efficiency by eliminating or minimising current losses between generating sources and consumers.
