The objective of this paper is to investigate the application of a Superconducting magnetic energy storage (SMES) system for enhancing transient stability. The SMES principles are used to develop models of both the SMES single bridge system and the double bridge system. Control strategies have been designed for active power control and a comprehensive control strategy for simultaneous modulation of active and reactive power. Computer simulations on both a single machine infinite system and a multimachine system show that SMES significantly improves the transient stability. The effect of active power control is compared to simultaneous active and reactive power control, the effect of the location of the SMES in the power system is also studied.
