Comparison of Methods

DDJEA

Prony Analysis

Real-time Applicability

Yes, the method converges for large systems before the next iteration.

Yes and No

The method can be a real-time application if the number of signals inputted is reduced to converge in real-time.

It cannot converge for very large systems unless the system order is reduced, adding inaccuracy to the results.

Immediate Event Detection

Yes

May take a few cycles

Slow Unstable Power Oscillation Detection

It can detect eigenvalues increasing toward singularity but may fail to flag as immediately as Prony if matrices appear to be approaching an equilibrium point early on.

Yes, this method excels at this type of detection.
