Abstract

The conceptual design of a 22 MWh superconducting magnetic energy storage (SMES) system engineering test model (ETM) has been developed. The objectives of the SMES-ETM are to demonstrate the feasibility of using a SMES system to perform load leveling and system stabilization for commercial utilities and to supply 400 MW power pulses for ground-based defense systems. The performance requirements and configuration of the proposed 22 MWh SMES-ETM and its power conditioning system are presented. The power conditioning system consists of a DC-DC chopper linked to a GTO-based voltage source converter interfacing the superconducting energy storage coil to the AC power system. >
