The problem of the weak hackto-back HVDC link is investigated by quasisteady-state analysis and small perturbation linearized stability analysis. The large ac line impedances on either sides of the HVDC link present severe constrain+s so that there may be no feasible steady-stave solutions unless a and y are co-ordinated with load demands. Formulae of steady-state stability limits, hunting frequencies, and voltage collapse are derived. One scenario for voltage collapse instability is discovered. A Composite Phasor Diagram is presented.

“…An electrical current flow can be essentially replaced with a heat flow by analogy with the Ohm's law 15,[17][18][19][20] ; however, an "inductor" is missing among components for thermal circuits 15,19 . This is because oscillatory behaviors, with a reversal in the direction of heat flow from cold to hot, are typically considered violations of the second law of thermodynamics 18,21 .…”

Reverse heat flow with Peltier-induced thermoinductive effect

et al. 2021

The concept of “thermal inductance” expands the options of thermal circuits design. However, the inductive component is the only missing components in thermal circuits unlike their electromagnetic counterparts. Herein, we report an electrically controllable reverse heat flow, in which heat flows from a low-temperature side to a high-temperature side locally and temporarily in a single material by imposing thermal inertia and ac current. This effect can be regarded as an equivalent of the “thermoinductive” effect induced by the Peltier effect. We derive the exact solution indicating that this reverse heat flow occurs universally in solid-state systems, and that it is considerably enhanced by thermoelectric properties. A local cooling of 25 mK is demonstrated in (Bi,Sb)2Te3, which is explained by our exact solution. This effect can be directly applicable to the potential fabrication of “thermoinductor” in thermal circuits.
