The standards of power system monitoring, control and protection are elevated by Phasor Measurement Units (PMUs) as an auspicious tool. It is the purpose of this paper to determine the optimal number and locations of PMUs so as to make the system measurement model observable and also estimate the power system state. The proposed modelling approach which models PMU placement as an integer linear...

The aim of this paper is to assess the capability of the emerging synchronized phasor measurement technology in improving the overall stability of the Hydro-Quebec’s transmission system through supplementary modulation of voltage regulators. Following a thorough singular value and eigenvalue analysis of the system dynamic interactions, five control sites consisting of four generators and one sy...

This paper proposes a novel approach for detecting the topology of distribution networks based on the analysis of time series measurements. The time-based analysis approach draws on data from high-precision phasor measurement units (PMUs or synchrophasors) for distribution systems. A key fact is that timeseries data taken from a dynamic system show specific patterns regarding state transitions ...

The smart grid will be a power grid more “aware” of its operating state and having the ability to self-heal. These features may be incorporated into the grid by implementing a phasor measurement units based wide area measurement system. Such a system will help in better real time monitoring and control of the grid. However, the wide area measurement system is subject to challenges with respect ...

The phasor measurement unit (PMU) is considered to be one of the most important measuring devices in the future of power systems. The distinction comes from its unique ability to provide synchronized phasor measurements of voltages and currents from widely dispersed locations in an electric power grid. This paper proposes an algorithm based on the clustering techniques for solving the optimal P...

The proposed method is simulated using a test signal in ideal...

Frequency estimation is a crucial signal processing technique in Phasor Measurement Units (PMU).
