ABSTRACT
Power system components, and particularly power circuit breakers, are witnessing an increased fault current scenario often beyond their interrupting capabilities. Since all electric vehicles use power electronics to get the batteries charged, in the long run this will certainly pose a challenge to electric utilities to keep the harmonic distortion levels within limits. Transmission line capacity has not kept pace with the generation capacity and load growth, with the result that transmission lines get subject to increasingly larger current under fault conditions, stressing many components on the electric grid. The operation of the superconducting fault current limiters magnetic core in the saturation region under normal operating conditions creates a level of harmonic distortion that is a function of the load current and the level of direct current bias applied to the magnetic core. Charging stations for electric vehicles are no doubt a challenge for mid- and long-term power systems. Assessment for the potential for smart charging may involve third-party providers.
