The recent advancement of synchrophasor measurements technology in the conventional power grid can monitor and control state variables network very accurately at a high sampling rate real-time. complete observability system states be achieved through Phasor Measurement Unit (PMU). inclusion zero injection bus (ZIB) optimized total number PMU requirements for observation network. communication c...

This paper explored a novel method for strategic monitoring of a power system to schematically monitor power system variables that are sensitive to transients. The characteristics of a fully developed transient or power swing increase frequency slip rates, generator pole slips, rotor out-of-step etc. whose effects lead to loss of synchronism of coherent generators in a power system. When these ...

This paper presents an approach to determine the optimal PMU locations in order to render the complete observability to given power system using BPSO. Quadratic programming approach is used in BPSO, and results so obtained are compared with GAMS-MIP solver. A Method for Pseudo observability is also proposed for depth-one and depth-two with and without Zero injection measurements for IEEE-7, IEE...

The power system industry has been going through dynamic infrastructural and operational changes in recent years that have caused more prominent lightly damped electromechanical oscillations. Real-time monitoring of electromechanical oscillations is of great significance for power system operators; to this aim, software solutions (algorithms) that use synchrophasor measurements have been develo...

Accurate knowledge of transmission line (TL) impedance parameters helps to improve accuracy in relay settings and power flow modeling. To improve TL parameter estimates, various algorithms have been proposed in the past to identify TL parameters based on measurements from Phasor Measurement Units (PMU’s). These methods are based on the positive sequence TL models and can generate accurate posit...
