Superconducting Magnetic Energy Storage unit, an efficient energy technology for power systems

Abstract

This paper discusses application of Superconducting Magnetic Energy Storage (SMES) unit to improve power system performance. The application of SMES unit in mitigating voltage sags and in damping dynamic oscillations in power systems is discussed. To show the effectiveness of the proposed controller in providing continuous voltage regulation and in enhancing power system dynamics, a three-phase short circuit is applied to the system and simulation is carried out with and with no SMES connected to the system. The results of these investigations are studied using the well-developed graphic facilities available in an industry standard power system package, namely PSCAD/EMTDC. Results have shown that SMES unit can effectively improve system stability and power quality of power systems.

Application of SMES Unit to Improve DFIG Power Dispatch and Dynamic Performance During Intermittent Misfire and Fire-Through Faults

“…The single wind turbine example used in this study is meant to simplify the investigation, introduce a new application for the SMES unit in WECS, and prove its effectiveness in improving system performance during DFIG converter faults. Although SMES TABLE II PARAMETERS OF DFIG AND PCC BUS TABLE III PARAMETERS OF TL TABLE IV DATA OF GRID TABLE V PARAMETERS OF SMES UNIT application in WECS is not commercialized yet, its superior technical advantages could qualify it as a competitive storage and management device in the near future, particularly with the global trend to develop smart grids [47]- [49].…”
