Abstract

This patent proposes one control paradigm for microgrids that can operate in ‎both grid-connected and islanded modes, hence, does not need ‎any sort of islanding detection method. The proposed method ‎automatically and seamlessly rides-through a fault on the grid ‎side, and controls the microgrid’s...
