In an earlier blog post we talked about converting the long distance transmission lines from AC to DC power, and infact there has been some recent movement towards this action. Dr. Steven Chu, Energy Secretary has made statements indicating that he supports a HVDC (High Voltage Direct Current) system of transmission lines to act as an energy super highway of sorts over the localized distribution system.
In Europe, a similar system has been advocated for by a policy group lead by Antonella Battaglini, has proposed a Super Smart Grid. It combines the Super Grid, which is a system of long distance HVDC lines with the applications of a Smart Grid, that uses technological advancements to redirect power flows, adjust for peak hours, and keep better data of demand. Essentially, the HVDC lines would run over the local transmission, which would still deliver the power in AC form over short distances. Thus the best of both worlds can be achieved. The European system would connect all of Europe and connect it with North Africa and the Middle East. Much has been discussed about developing solar generators in parts of Africa and then transporting power all over Europe, thus reducing Russia’s hegemony over energy supply. The Super Smart Grid is an interesting proposal, that the US can hopefully take some ideas away from.
