In low voltage (LV) distribution systems, the problem of overvoltage is common during lower load intervals. This arises because high value R/X ration these systems. Many techniques are available in literature to cope up with this at converter level; mostly methods control reactive or active power photovoltaic (PV) However, there certain restrictions and complications PV Most have been implement...

The photon detection system of the first far detector (FD1-HD) DUNE experiment will detect scintillation photons produced by particle interactions in a kiloton-scale liquid Argon time projection chamber. detectors choice are silicon photomultipliers (SiPM), 6$\times$6 mm$^2$ each, arranged groups 48, which present significantly low impedance to front-end electronics. This paper details design c...

The stochastic behavior of PV together with high penetration have given rise to power quality concerns involving voltage dynamic issues such as undervoltage, overvoltage, sag and swell. To ensure the grid’s stability, various methods been practiced a proper sizing grid lines installation compensation equipment. However, these measures often require costs control complexity due additional equipm...

The recently stipulated grid codes require wind generators to re-initiate normal power production after voltage sag. This paper presents a comparative performance of two commonly employed variable speed turbines in today’s electricity market, the doubly fed induction generator (DFIG) and permanent magnet synchronous (PMSG) turbines. evaluation both was performed for weak, strong grids, consider...

Mitigating switching overvoltages (SOVs) and conducting well-suited insulation coordination for handling stresses are very important in UHV transmission Lines. The best strategy in the absence of arresters is controlled switching (CS). Although elaborate works on electromagnetic transients are considered in the process of designing transmission systems, such works are not prevalent in day-to-da...

Wind energy is a good alternative to fossil fuels, as the use of fuels has seriously exacerbated emission greenhouse gases such carbon dioxide and greatly affected environment. Conventional AC wind farms transmission systems inevitably face problems involving reactive currents overvoltage in context large-scale, large-capacity, long-distance transmission. However, all-DC turbines, together with...
