| Popis: | A connection is established between the system-theoretic notion of modal observability, and the indices guaranteeing robust signal recovery– denseness and restricted isometry. Insights are derived for grouping signals to ensure guaranteed recovery of synchrophasor measurements corrupted with sparse and spurious anomalies. The propositions on signal grouping are validated on simulated data from a IEEE test system, as well as field PMU measurements from a US utility. |
