  • Some of the above-listed disadvantages can be eliminated with the use of new technologies. In particular, disadvantages such as a complete power fault of the HVDC transmission system during short-circuits inthe AC power system and reactive power consumption can be eliminated completely, or mostly, with the use of turn-off thyristors.Several research centers are working on improving high-capacity turn-off thyristors and also on new types of converter devices for high-capacity HVDC transmission.Finally, there are several new techniques for the perfection of grounding devices, providing for decreased electro-corrosion impacts and the formation of so-called “metal return”, which precludes the working current from flowing through the ground. Other techniques aimed at perfecting HVDC technology are also being developed (Koshcheev 2001).

  • According to the report, approximately 333 gigawatts (GW) of new HVDC transmission capacity will be added between 2013 and 2020.  For comparison, peak demand in the United States is estimated to be approximately 800 GW in 2013.  In China alone, nearly 200 GW of new HVDC transmission capacity is planned for build-out over the next 8 years.  Energy from hydroelectric generation in distant inland locations will be tapped and transported to power big cities along the eastern and southern coast.

  • What's the key to using alternative energy, like solar and wind? Storage -- so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap." Donald S

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

  • Virtually all construction of new HVDC systems is occurring in Europe, India, China and North America. Growth in each of these regions is being driven by different forces: while rapid economic growth and the drive to complete national electrification programs are fueling HVDC systems in China and India, Europe will see large amounts of renewable generation, along with the interconnection of many national grids into a unified continent-wide system. In North America, meanwhile, three-quarters of planned future investment in HVDC comes from "merchant" transmission companies, due to the balkanized regulatory framework of the region.

  • There’s little doubt that HVDC will continue to be rolled out by most utilities, but the costs and complexity mean an HVDC supergrid is some way off. Innovation doesn’t stand still, however, and advances in key areas that reduce equipment costs, aid development of IT tools and control algorithms, could one day make the case for supergrids irresistible.

    Nexans, the large French wire and cable maker, announced that it has won a EUR80M (USD104.5M) contract to supply and install a 100km long high voltage direct current (HVDC) submarine cable in Newfoundland, Canada. The cable will form part of a new HVDC transmission link in Canada that stretches 1,100km. The submarine cable, which uses copper wire as its conductive core, will be manufactured in the company's NVC factory in Tokyo. The announcement is the second large submarine cable contract the company has won in the last 3 months, following the announcement that Nexans won the contract to supply and install a EUR300M (USD387.4M) submarine cable connecting Italy and Montenegro in late October 2012.

  • 1. Industry outlookThe report's baseline deployment forecast, shows Europe achieving between 26 - 27GW of installed capacity by 2020, of which around 23GW is new installations.Such deployment would:- Occur mainly in the UK and Germany.- Require around 3,500 turbines plus associated infrastructure.- Cost upwards of £75 billion (€86 billion) based on current industry practices.2. Power cable demandGrowth in resulting cable installations will be significant, with an estimated 6,000km of export cable, 2,000km of EU inter-connector cable and 6,500km of array cable installations by 2020.The report's findings show:- In terms of total cable installations, the report predicts that demand will more than double over the period to 2020, with growth of between 2.5 and 3.0 times that of 2011 occurring in both export and array installations.- A near-doubling of export and inter-connector installations by 2016. Thereafter, growth is limited as HVDC use increases and general industry growth slows.- A 250% rise in array cable installations from 350km in 2011 to 900km by 2020.3. Export cable supply vs. demandThe authors estimate that annual export cable installation supply currently stands at around 600 - 650km (vs. 500km 2011 demand). Identified capacity additions are limited. Our analysis shows that export cable installation capacity needs to increase by around 75% within 2 - 3 years if demand is to be met.

  • Developing countries such as China, India and Brazil have large populations and are modernizing quickly, but closing the gap with the developed world will require a large amount of electric power. HVDC is the most environmentally friendly and economical way of transmitting large amounts of electric power. Compared with AC, DC transmission needs much narrower right-of-ways, while higher voltages reduce both electricity losses and the cost of building large-scale power lines. As generation takes place further and further away, higher and higher transmission voltages are required. The highest DC transmission voltage has almost doubled during the last decade

  • Using the Siemens technology installed on the platforms, the alternating current power generated by the wind turbines is transformed into direct current for efficient transmission to the mainland. At the associated land-based stations, the electricity generated by the connected wind farms is converted back into the alternating current power required for feeding into the transmission grid.
