Extended properties of nonlinear power system models that are symmetrically configured in the narrow sense
Published 2025-03-01“…Three-phase circuits that are Symmetrically Configured in the Narrow Sense (SCNS) have been defined in previous works as circuits which dq0 dynamic model does not depend on the transformation’s reference angle. This property leads to dynamic models that are linear and time-invariant in the dq0 reference frame, or at least suitable for low-complexity numerical analysis, which is crucial when studying large-scale power systems. …”

Modification of Cellulose by Esterification Crosslinking to Manipulate Its Microstructure for Enhanced Sodium Storage in Hard Carbon
Published 2025-01-01“…The active hydroxyl group of cellulose plays a crucial role in regulating the microstructure of cellulose-derived hard carbon, which ultimately affects its sodium storage capacity. Through small-angle X-ray scattering (SAXS) and X-ray atomic pair distribution function (PDF) analysis, we proved that modification of cellulose by esterification crosslinking can introduce more closed pores into the carbonized hard carbon, which is beneficial for promoting sodium ion storage. …”
