Overloading Scenario in Solid State Transformer [PDF]
Nowadays, solid state transformer (SST) is been considered as an alternative option in smart grid where additional ancillary services that cannot be provided by conventional line frequency transformer (LFT) are required. However, the power transmission capability of SST is limited to that of its semiconductor switches which are power electronics ...

Energy Management Strategy of AC/DC Hybrid Microgrid Based on Solid-State Transformer
Voltage fluctuation and power mismatch which are caused by the decentralization, randomness, and intermittence of distributed energy resource along with load variability cause severe impacts on the security and quality of power network operation.

The Need for Experimental and Numerical Analyses of Thermal Ageing in Power Transformers
Most power transformers are oil-immersed transformers for which its insulation system consists of oil and cellulosic solid. The insulation liquid impregnates the solid-covering air spaces, which improves the efficiency of the insulation system.

Calpain small subunit homodimerization is robust and calcium‐independent
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
