HVDC: The Key to Revolutionizing the Renewable Energy Grid

Alstom Grid recently opened its worldwide center of excellence for HVDC, as well as its large-scale transformer factory in Stafford, England, to more than a dozen journalists from around the world to talk about the future of HVDC. The company cited the benefits of HVDC and how the technology is helping connect mass amounts of renewable energy to the grid and transfer it long distances to load centers. There are two types of HVDC technologies: Line commutated converters (LCC), which encourage energy trading and HVDC transmission; and, voltage source converters (VSC), which enables renewable energy by connecting variable energy resources and DC grids. LCC is ideal for major bulk power projects, while VSC is better suited for more compact projects, according to Alstom Grid. “If a line is spanning a distance of more than 700 km (435 miles), it’s typically more cost efficient t...
