The penetration of the distributed power generation systems (DPGSs) based on renewable sources (PV, WT) is strongly dependent on the quality of the power injected to the utility grid. However, the grid impedance variation, mainly caused by grid faults somewhere in the electric network, can degrade the power quality and even damage some sensitive loads(More)
This paper presents a fast passive islanding detection method based on virtual phase-shift between the real voltage seen at the point of common coupling and its created image in a Microgrid. The proposed algorithm consists of extracting the positive and negative sequences of the voltage at this point using a second order generalized integrator in two-way;(More)
