• This paper studies the perspective of the SMES (superconducting magnetic energy storage) technology applying in on-line dynamic security monitoring and assessment of power systems. Unlike other applications of SMES in power systems, such as, as energy storage systems and power system stabilizers and so on, this new application takes advantage of the flexible energy output mode of SMES to generate periodic power signals with special waveform as a disturbance source, then oscillation modes on this operating condition can be excited without affecting power systems security. Measuring and analyzing the frequency response curves at buses, the movement of system oscillation modes can be obtained while operating conditions of power systems vary, sequentially dynamic security can be assessed.
