Abstract
A smart link in a power delivery system includes an insulator, which electrically isolates a power line, and a switchable conductance placed in parallel with the insulator. The switchable conductance includes switchgear for sourcing, sinking, and/or dispatching real and/or reactive power on the power line to dynamically in response to dynamic loading, transient voltages and/or currents, and phase conditions or other conditions on the power line.

1-21. (canceled)
A variable-voltage high-voltage AC transmission line system, comprising:
- a transmission line section extending from a first upstream voltage-changing device to a first downstream voltage-changing device, wherein the first upstream voltage-changing device has a respective input voltage Vin(1) and the first downstream voltage-changing device has a respective output voltage Vout (1);
- and
- a system controller coupled to the first and second voltage-changing devices, wherein the system controller is arranged to coordinate changes associated with the first voltage-changing upstream device and the first downstream voltage-changing device to change a voltage of the transmission line section from a first value V1 to a second value V2 while keeping the respective output voltage Vout (1) substantially unchanged.

A method, comprising:
- in a variable-voltage high-voltage AC transmission line system having a transmission line section extending from a first upstream voltage-changing device to a first downstream voltage-changing device, wherein the first upstream voltage-changing device has a respective input voltage Vin(1) and the first downstream voltage-changing device has a respective output voltage Vout (1),
- coordinately adjust the first upstream voltage-changing device and the first downstream voltage-changing device to change a voltage of the transmission line section from a first value V1 to a second value V2;
- and
- keep the respective output voltage Vout (1) substantially unchanged by the change in voltage of the transmission line section from a first value V1 to a second value V2.
