Open communication system in modern power systems brings concern about information staleness which may cause power system frequency *** information staleness is often characterized by communication ***,communication delay is a packet-centered metric and cannot reflect the requirement of information freshness for load frequency control(LFC).This paper introduces the age of information(AoI),which is more compre-hensive and informative than the conventional communication delay modeling *** LFC controller and com-munication are integrated into the design for LFC performance *** AoI-aware LFC model is formulated first,and considering each allowable update period of the smart sensor,different AoI-aware PI controllers are then designed according to the exponential decay *** right AoI-aware controller and update period are selected according to the degree of frequency fluctuation of the power *** studies are carried out on one-area and two-area power *** results show the superior performance of the AoI-aware controllers in comparison to the delay-dependent controllers.

We introduce a taxonomy for partially coherent optical fields spanning multiple degrees of freedom (DOF) based on the rank of the associated coherence matrix (the number of nonzero eigenvalues). When DOF comprise two spatial modes and polarization, a fourfold classification emerges, with rank-1 fields corresponding to fully coherent fields. We demonstrate theoretically and confirm experimentally that these classes have different properties. Specifically, whereas rank-2 fields can always be rendered separable with respect to its DOF via a unitary transformation, rank-3 fields are always nonseparable. Consequently, the entropy for a rank-2 field can always be concentrated into a single DOF (thus ridding the other DOF of statistical fluctuations), whereas some entropy is always “locked” in one DOF of a rank-3 field. These results offer insight into the dynamics of optical coherence upon traversing systems or media that couple DOF.

Gallium nitride-based high-electron-mobility-transistors(HEMTs) have gained widespread interest and become primary candidates for next-generation high-frequency and high-power RF electronics, due to their wide bandgap,high breakdown field, and strong polarization-induced high-density 2-dimensional electron gas(2DEG) at the heterojunction interface.
