A numerical method for observability analysis based on givens rotations

Classical observability analysis methods that are based on decoupled network equations cannot be directly applied to systems containing voltage and current phasor measurements, since the equations can no longer be decoupled when current phasor measurements are present. Moreover, conventional voltage magnitude measurements are commonly disregarded in conventional observability analysis methods. This paper proposes a method to incorporate phasor measurements as well as voltage magnitude measurements in observability analysis.Index Terms-Phasor Measurement Units, network observability analysis, state estimation.
