Abstract The objective of this study is to oversee the operation several converter-based distributed generations in order assure efficient power distribution inside an island-microgrid (MG). commences by introducing a MG model that integrates virtual impedances with phase-locked loop. It subsequently presents unique method for analyzing small-signal stability islanded MGs. A impedance setting strategy created using gray wolf optimization algorithm. was found voltage and frequency stay within acceptable boundaries. index much increased reactive imbalances were eliminated.
