David Wagman reports in a 10 Oct 2017 article at the Institute of Electrical
and Electronics Engineers (IEEE) Spectrum magazine web site on
simulations being run under the auspices of the US Energy Department
to test the viability of stabilizing national power grids by interconnecting
them to power grids on other continents using High Voltage Direct
Current (HVDC) interconnects.

It’s no stretch to imagine a hurricane cutting electric power across a wide swath of the United States, upsetting grid stability. The researchers wondered: Would be possible to stabilize the grid in such a situation using a high voltage direct current (HVDC) line reaching between the U.S. and, say, Europe, allowing grid operators to tap into excess generating capacity?
More to the point of the late September test, the researchers wanted to learn whether multiple systems on different continents could work simultaneously to balance the grid after a simulated disruption?
The answer is yes, but with a few qualifications.
The Energy Department’s Idaho National Laboratory (INL) led the international team in testing what is known as the Real-Time Super Lab. The concept is integral to an effort to learn how electricity can be rerouted across vast distances to rapidly stabilize grids after a disruption.
The team envisions that large-scale blackouts could one day be prevented by moving electricity intercontinentally. The concept mirrors the way utilities already move power regionally.
