Overview of Superconductivity in Power Systems Applications

Le reti attive del futuro collegheranno efficientemente le sorgenti di potenza di piccole e medie dimensioni, in particolare da Fonti Energetiche Rinnovabili (FER), con le richieste dei consumatori, consentendo di definire in tempo reale la migliore gestione del sistema elettrico. Certamente le maggiori sfide del futuro consisteranno nell’integrare risorse di produzione più sostenibili, soddisfare la crescente domanda di energia elettrica e rinnovare le reti elettriche. Le applicazioni di potenza dei materiali superconduttori hanno le potenzialità per svolgere un ruolo importante nell’affrontare queste sfide: i recenti successi di una serie di prototipi, infatti, hanno sottolineato la fattibilità e le superiori prestazioni della tecnologia a superconduttore rispetto ai dispositivi e ai componenti convenzionali.

Future active networks will efficiently link small- and medium-scale power sources, especially from Renewable Energy Sources (RES), with consumer demands, allowing decisions to be made on how best to operate the electricity system in real time. An intelligent grid infrastructure gives more flexibility concerning demand and supply, providing new instruments and devices for optimal and cost-effective grid operation. Certainly, the major future challenges will be to integrate more sustainable generation resources, meet growing electricity demand and renew electricity networks, and superconducting power applications have the potential to play an important role in addressing these challenges. In fact, since the discovery of high-temperature superconductivity (HTS), in 1986 there has been a rapid progress in developing superconducting materials, wires and applications. Especially for large-scale power applications like cables, fault current limiters, transformers, superconducting magnetic energy storage devices, and rotating machines a number of recent successful prototypes underlined the feasibility and superior technical performance of superconductor technology as compared to conventional devices and components. This lecture will summarize the state-of-the-art of different HTS power applications, give a short outlook on the most important future R&D topics and challenges, and outline the potential of superconducting power applications to contribute on electricity system efficiency and hence to the reduction of CO2 emissions. In addition, the HTS material main requirements for the different power applications and indications about the role of superconducting power application in smart grids will be presented and discussed.
