Static-Synchronous Compensators and Superconducting Magnetic Energy Storage Systems in Controlling Power System Dynamics: Statcom-Smes

SUPERCONDUCTING MAGNETIC energy storage (SMES) systems for power utility applications have received considerable attention due to their characteristics, such as rapid response (milliseconds), high power (multimegawatts), high efficiency, and four-quadrant control. SMES systems can provide improved system reliability, dynamic stability, enhanced power quality, and area protection [l]-[7], as its potential applications are summarized in Fig. 1 [7]. The squared area indicates the possible cost-effectiveness of SMES applications. Advances in both superconducting technologies and the necessary power electronics interface have made SMES a viable technology that can offer flexible, reliable, and fast-acting power compensation.
