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. |
