An interconnector (also known as a DC tie in the USA [1]) is a structure which enables high voltage DC electricity to flow between electrical grids. An electrical interconnector allows electricity to flow between separate AC networks, or to link synchronous grids .
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

The HVDC Cross-Channel (French: Interconnexion France Angleterre IFA 2000) is the 73-kilometre-long (45 mi) high-voltage direct current (HVDC) interconnector that has operated since 1986 under the English Channel between the continental European grid at Bonningues-lès-Calais and the British electricity grid at Sellindge.
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
The Texas Interconnection is maintained as a separate grid for political, rather than technical reasons, [1] but can draw some power from other grids using direct current DC ties. By not crossing state lines, the synchronous power grid is in most respects not subject to federal ( Federal Energy Regulatory Commission ) regulation.
The Eastern Interconnection is tied to the Western Interconnection with six DC ties, to the Texas Interconnection with two DC ties, and to the Quebec Interconnection with four DC ties and a VFT. In 2016, National Renewable Energy Laboratory simulated a year with 30% renewable energy (wind and solar power) in 5-minute intervals. Results show a ...
The Sodo–Moyale–Suswa High Voltage Power Line (or Ethiopia–Kenya HVDC Interconnector) is a 500 kV bipolar high-voltage direct current electricity power transmission line connecting Ethiopia with Kenya. It was completed in November 2022.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
