Recently we got published an article on short circuit current limiting on Elevier’s Electric Power Systems Research, were I’m a co-author;
“Performance analysis of a Superconducting Fault Current Limiter in a power distribution substation”, Volume 136, July 2016, Pages 89–99

The results of the research and pilot project for this technology are promising. The short circuit current limiting with a superconducting system (SFCL-Superconducting Fault Current Limiter) is an example of FACTS (Flexible AC Transmission System) for the Smart Grid. It allows a real-time response, that is an automatic reaction, reducing short circuit currents, thus avoiding damage to equipment. This enables a more meshed operation while the energy losses are kept low.
The paper presents the operational benefits and performance of an installed system in a distribution network. These benefits are translated into economic terms, with the goal of setting a target price for economic feasibility of such systems. While the difference between the economic target of 100 k€ and the cost of the real project is tenfold, it remains a trigger for market adoption. Moreover, it is likely that economies of scale and technology improvements drive the implementation cost down in the coming years.
The consequence of widespread use of SFCL would be more reliable and resilient distribution networks. We will see more of this coming, in the near future.
