A New Approach for Long-Term Stability Estimation Based on Voltage Profile Assessment for a Power Grid

open access: yesEnergies, 2023
Load flow solutions refer to the steady-state stability of power systems and have a crucial role in the design and planning of slow-changing elements; e.g., in online tab changing actions, automatic generation control, over-excitation limiters and the ...

Interaction effects in superconductor/quantum spin Hall devices: universal transport signatures and fractional Coulomb blockade [PDF]

open access: yes, 2016
Interfacing s-wave superconductors and quantum spin Hall edges produces time-reversal-invariant topological superconductivity of a type that can not arise in strictly 1D systems. With the aim of establishing sharp fingerprints of this novel phase, we use
