Modern Power Transmission Systems

The majority of transmission systems were designed and constructed decades ago. Their initial design was for the transmission of electric power mainly generated at few, large centralised power plants into meshed sub-transmission network supplying consumers. Overhead lines were used exclusively, except in dense urban areas, and international connections were limited.

Much changed since them and new challenges exist nowadays, as to include the large and ever increasing amounts of decentralised generated power into the existing transmission network, while complying with the electricity market transmission demands and assuring a very high security of supply. Furthermore, public opinion in many countries reacts against the erection of new overhead lines, which would ease some of the challenges. Many started introducing underground cables in the respective transmission grids, in order to address this problem, but to do so introduces new challenges, as a decrease in power quality, higher financial costs or a more complicated voltage control.

In parallel, special attention is directed towards large offshore wind generation plants, increasing cross-border connections and potential offshore transmission network in the North Sea, a gigantic and game changing vision – a vision that could be based upon the latest HVDC-VSC technology.

All of these are working areas for the Modern Power Transmission Systems research program and we try to provide new solutions able to assure an efficient, environment friendly and high quality electricity delivery for the electric power system of today’s future.
