Multi-objective decoupling control strategy for low voltage ride through under asymmetrical faults

电力工程技术
For the traditional low voltage ride through control under asymmetrical faults, due to the limited control degrees of freedom, the grid-connected inverter control suffers from the problem of not being able to simultaneously realize the output current ...

From Phosphinimines to Four‐Membered SiCPN Cations: Insights Into N–Si Bonding and Ring Strain

European Journal of Inorganic Chemistry, EarlyView.
Sterically tuned N‐silyl phosphinimines enable four‐membered SiCPN cations. Hydride abstraction yields cyclic cations for Me and iPr substituents at silicon, while tBu gives a protonated intermediate. Multinuclear NMR spectroscopy, X‐ray crystallography, thermochemical density functional theory investigations, and natural bond orbital analyses reveal ...

On the Verge of Exclusion: The Unique Psychological Profile of the Threat of Social Exclusion

European Journal of Social Psychology, EarlyView.
ABSTRACT Past research, often using Cyberball—an online ball‐tossing game with two or more preprogrammed players—showed that being socially excluded produces various negative emotions and lower need satisfaction. However, in everyday life, people may experience the threat of social exclusion more frequently than actual exclusion. Across two experiments
