SMES stores energy in the form of a DC circulating current, with the discharge voltage determined by the required power delivery, whereas the target electric utility bus delivers AC (typically 50 or 60 Hz) electrical power. A PCS is required to move power back and forth between the SMES storage medium and the electric utility bus.
