Regional frequency response analytical model for three-region interconnected power systems considering fast frequency response resources

Frequency Response (FR) is critical for mitigating frequency fluctuations and maintaining stability in power systems, particularly as modern power systems integrate more renewable energy. This paper addresses the challenges of increased frequency variability and decreased FR capa...

Tertiary Hydroxylaminesas Bifunctional Single-NitrogenSources for De Novo Spirooxindole Synthesis

Abstract We herein report a palladium-catalyzed cascade reaction that enables the de novo synthesis of spirooxindoles from simple ortho-iodoaniline derivatives, in which tertiary O-benzoyl hydroxylamines serve as bifunctional single-nitrogen sources through sequential C–H diamina...
