Call for papers for a EJEE Special issue on “HVDC power networks”
OBJECTIVE. The increase of electricity demand (energy and peak power) requires new generation facilities. Worldwide the main primary sources are fossil (coal, oil and gas), and low prices for coal make this energy very competitive to generate electricity. Nevertheless all countries now agree th at CO2 emissions must be reduced. Then CO2 ‐ free power plants must be a priority. Beside the hydro and nuclear plants, other sources must be found. In that way wind and solar energies are an opportunity for carbon ‐ free generation. But the main reserves are offshore (wind) or in the north ‐ African desert (solar). In Europe, the North Sea has a great potential for wind generation. It will then require new infrastructures to transfer power to the consumers. As cabled lines must be used, the long distances make the AC technology not suitable (too much capacitive current ). Then the DC technology is necessary, with multi‐terminals and meshed topology. The main objective of this special issue of European Journal of Electrical Engineering is to explore the High Voltage Direct Current (HVDC) power networks: their integration inside the AC interconnected systems, their connection with large renewable sources, their specific equipment, and their control.
