This article presents a new passive islanding detection technique in MGs that uses locally measured voltage signals at the PoC of DERs. The proposed method distinguishes events from normal/non-islanding conditions by utilizing superimposed harmonic spectra extracted through full-cycle discrete Fourier transform. Our solution utilizes machine-learning-based one-class classifier to define and adj...

In the arena of modern electrical power distribution systems, distributed generators (DGs) are emerging as a manifestation electric personalization. Even though DGs have various advantages, unintentional islanding phenomena caused by during abnormal grid operations can damage equipment connected to grid. Therefore, detection mechanisms essential for in grid-connected mode disconnect DG from cas...

Renewable energy (RE) generation levels are increasing in modern power systems at a fast rate due to their advantages of clean and non-exhaustible nature energy. However, this type creates technical challenges terms operation control uncertain un-predictable generation. Islanding is an operational scenario where there loss grid RE generators continue feed the local load. This has harmful effect...

The recent growing diffusion of dispersed generation in low voltage (LV) distribution networks is entailing new rules to make local generators participate in network stability. Consequently, national and international grid codes, which define the connection rules for stability and safety of electrical power systems, have been updated requiring distributed generators and electrical storage syste...

Power grids, throughout the world, are operated as large interconnected networks to ensure reliability of supply in an economic way. The interconnected nature of power network makes it vulnerable and sometimes even a small disturbance in the grid may propagate and result in a blackout. Investigations into major blackouts of the decade in the world have identified inadequate monitoring of the dy...

This paper proposes a novel islanding detection method (IDM) for grid-connected photovoltaic systems (GCPVSs) through disturbance injection in the maximum power point tracking (MPPT) algorithm. When an absolute deviation of output voltage exceeds threshold, applied shifts system operating from its (MPP) condition. leads to sharp active reduction and consequently, significant drop islanded mode ...
