400MW SMES power conditioning system development and simulation
A conceptual design for a 22 MWh superconducting magnetic energy storage (SMES) system engineering test model (ETM) has recently 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. This paper presents the performance requirements and configuration of the proposed 22 MWh SMES-ETM and its power conditioning system. 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. The SMES system operation in the charging and discharging modes is described and the results of digital simulations demonstrating the feasibility of the proposed power conditioning system and exploring its overall behavior under normal and fault conditions are presented.
