Researchers have sharply increased the sensitivity and speed of quasi-2D perovskite photodetectors by carefully tuning how they interact with silver plasmonic nanostructures, according to a new study ...
Abstract: In grid-connected inverter (GCI), the asymmetrical control structures lead to frequency coupling effect, complicating system analysis and threatening grid stability. To suppress frequency ...

Inter-Sequence Coupling Estimation and Frequency-Compensated PLL of DFIG During Asymmetric Weak Grid
Abstract: Under asymmetric weak grid conditions, the coupling between the positive and negative sequences in doubly fed induction generator (DFIG), introduced by the phase-locked loop (PLL), can ...
ABSTRACT: Instabilities in grid-connected inverters can arise from a number of sources, including mismatched parameters, grid impedance, faults, and feedback delays. Park’s transformation provides ...

With the decreasing cost of energy storage, PV-coupled storage applications are becoming more and more attractive for a broad range of applications. Further drivers for this development are the ...
The Department of Energy’s (DOE) national laboratories are hard at work developing ways to ensure microgrids work their magic. For example, two national laboratories — the Pacific Northwest National ...
