SIL Modeling of Shunt Harmonics Active Filter
, 2020 The evolution in semiconducting devices has introduced flexible control on a system but it has also penetrated harmonics in the grid, which results in extra electrical stress and load. Limiting the presence of harmonics in the grid and low power factor maintained by consumers has become of utmost priority to the power system analyst.

An Enhanced Shunt Active Filter Based on Synchronverter Concept
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022 This article proposes a shunt active filter (SAF) operating as a Synchronverter to enhance its performance, including the virtual inertia functionality. The SAF behaves as a voltage source with a low-impedance path for harmonic contents. Synchronverter behavior is used together with selective filtering through proportional-resonant controllers to ...
