An ANN based FDL employing DWT based fault feature mining for grid connected PV inverters is proposed, which incorporates thermal overstress and wear out failures in IGBTs using MATLAB/PLECS integration. This work develops two classifiers, which are able to work in both component failure and degradation conditions.
As of April 2025, islanding detection for grid-forming inverters is still an emerging topic. Indeed, only very few publications are available. In principle, all passive techniques designed for grid-feeding applications also apply to grid-forming inverters. However, passive methods alone still present an NDZ or suffer from selectivity problems.
Despite that, islanding detection seems to have nonetheless become a de-facto mandatory feature for grid-connected inverters, mostly driven by US and Japanese standards.
