Empirical mode decomposition based algorithm for islanding detection in micro-grids

Owning to extensively enhancement of renewable energy resources in the distribution grids, employment such sources is also associated with various issues as islanding problem. In this paper, an effective method has been proposed for detection micro-grids comprised inverter or direct fed types distributed generations. The designed based on intrinsic modes voltage signal measured at PCC point. More specifically, through calculation positive sequence variation (PSVSV) and extracting PSVSV's modes, can be detected. superiority manifested condition where generation balance loading consumption. performance evaluated considering conditions difficult detect might mistaken other phenomena given by loads within NDZ region, different fault types, power factors. evaluation carried out simulations, furthermore compared state-of-the-art algorithms.
