“…A hybrid dynamic simulation method is proposed in [66,67] to locate the oscillation source, which is based on both the system model and the measurement data. The location idea is to first replace part of the differential and algebraic variables, say V p , with known measurements and perform the time domain simulation for the rest of the variables, say V r .…”

The deployment of a synchrophasor-based widearea measurement system (WAMS) in a power grid largely improves the observability of power system dynamics and the operator's real-time situational awareness for potential stability issues. The WAMS in many power grids has successfully captured system oscillation events, e.g. poorly damped natural oscillations and forced oscillations, from time to time. To identify the root cause of an observed oscillation event for further mitigation actions, many methods have been proposed to locate the source of oscillation based on different ideas and principles. However, most methods proposed so far for locating the oscillation source in a power grid are not reliable enough for practical applications. This paper presents a comprehensive review of existing location methods, which basically fall into four major categories, plus a few other methods. Their advantages and disadvantages are discussed in detail. Some trends and challenges on the problem of oscillation source location are pointed out along with potential future research directions. Finally, a practical, general scheme for oscillation source location using available location methods is suggested and analyzed.
