Establishment of an auxiliary virtual damping loop for the superior inertial response in the microgrid

IET Smart Grid, 2019
Low inertial microgrids in the power network are extremely sensitive toward any uncertainties. Therefore, the practise of complementing inertia virtually in microgrids has earned huge attention in recent time.

Energy Storage Sizing for Wind-Storage Frequency Regulation: Kinetic Energy Recovery and Secondary Frequency Drop Suppression

Energies
High wind power penetration aggravates power system inertia scarcity, and wind turbines switching to MPPT mode after virtual inertia support induces secondary frequency drop (SFD), impairing grid frequency stability.

Cerium Nanoparticle‐Mediated Inhibition of the NSUN2/m5C Axis Suppresses Synovial Aggression in Rheumatoid Arthritis

Advanced Science, EarlyView.
A novel epitranscriptomic mechanism in rheumatoid arthritis is uncovered: NSUN2 promotes disease via m5C‐dependent stabilization of ICMT mRNA, fueling the migration and invasion of pathogenic RA FLS. Targeting this axis with engineered nanoparticles (Ce/SAA NPs) effectively inhibits disease progression, presenting a precise therapeutic strategy ...
