Estimation of interarea electromechanical modes during ambient operation of the power systems using the RDTITD method
The RDTITD was proposed to estimate the interarea modes in the power systems. The RDTITD was compared with RDT-Prony, NExT-ERA and N4SID. The RDTITD is robust to measurements noise, and has high computational efficiency. The RDTITD was validated using real PMU data from Sichuan power grid of China.
