In this paper a new algorithm based on phasor measurements for estimating the Thévenin Equivalent (TE) and system inertia constant is proposed. The method estimates the network TE seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at Phasor Data Concentrator (PDC) center. It is shown that the parameters of the TE could be estimated at...

The implementation of synchronous phasor measurement units (PMUs) in distribution networks provide accurate and GPS-based data which support the grid flexible reconfiguration, such as island partition reconnection. Utilizing high resolution PMU data, phase angle droop control can be implemented on islanded microgrids (MGs) without causing deviation frequency brought from traditional control, co...

in this paper, a novel neuro-fuzzy based method combined with a feature selection technique is proposed for online dynamic voltage stability status prediction of power system. this technique uses synchronized phasors measured by phasor measurement units (pmus) in a wide-area measurement system. in order to minimize the number of neuro-fuzzy inputs, training time and complication of neuro-fuzzy ...

Event detection and analytic calculations in both Wide Area Measurement Systems (WAMS) and in distribution systems including Phasor Measurement Unit (PMU) based microgrid control systems often use the independent components of the phasors (e.g. frequency or Voltage) rather than the vector representation of a phasor. This paper introduces the use of the discrete time complex Fourier Transform ba...

Nowadays, in modern management and control applications, line parameters need to be known more accurately than the past achieve a reliable operation of distribution grids. Phasor Measurement Units (PMUs) may improve estimation processes, but accuracy result is affected by all elements PMU-based measurement chain, particular instrument transformers. Current transformers (CTs) are nonlinear there...

Time-synchronization attacks on phasor measurement units (PMUs) pose a real threat to smart grids; it was shown that they are feasible in practice and can have nonnegligible negative impact state estimation, without triggering the bad data detection mechanisms. Previous works identified vulnerability conditions when targeted PMUs measure single phasor. Yet, capable of measuring several quantiti...

This paper presents a new methodology for correcting gross errors in power distri- bution systems state estimation (SE). A SE algorithm is developed based on the Weighted Least Squares (WLS) using hybrid approach which non-synchronized measurements and PMUs (Phasor Measurement Units) are used together. At end of process, Normalized Residuals (NRs) calculated each measurement existence detected ...

Abstract Large-scale power grid observability is still a challenge because of deteriorating infrastructure and the incorporation renewable energy sources. A smart that makes use cutting-edge technology, such as phasor measurement unit (PMU), an excellent option for monitoring bringing networks up to speed with latest information. Latterly, considerable investment required deployment locations h...
