Abstract: In this work the harmonic injection active anti-islanding technique that has been recently proposed in reference Voglitsis et al. (2018) published in Trans. Power Electron. is generalized under the prospect of a high penetration level of distributed energy resource (DER) installations. Towards this direction, the theoretical limitation for the penetration level of such schemes is investigated and a firm theoretical background is presented that takes into account the installation parameters, as well as the penetration level at the installation common coupling point. Furthermore, a substantial feature which indicates the upgrade-ability of each installation is studied. Finally, extensive simulations and experiments verify the theoretical analysis.
