In a large and complex interconnected power system, the measurement of synchronized bus voltage line current plays vital role in monitoring precise control various sophisticated electrical equipment for secure reliable operation. Phasor units (PMUs) are incorporated into wide area system to extract different signals phasors. this paper, capacity PMU phasor estimation algorithm is explored based...

This paper aims to find strategic locations for additional Phasor Measurement Units (PMUs) installation while considering resiliency of existing PMU measurement system. A virtual attack agent is modeled based on an optimization framework. The virtual attack agent targets to minimize observability of power system by coordinated attack on a subset of critical PMUs. A planner agent is then introdu...

Secure operation of power systems is receiving a renewed interest due to considerable structural changes and greater uncertainties. Thus, motivated by implementation of wide-area measurement systems in power systems worldwide, recent research work is being devoted to the development of enhanced tools for fast security assessment within reduced time frames. The work presented in this paper intro...

The new standard C37.118.1 lays down strict performance limits for phasor measurement units (PMUs) under steady-state and dynamic conditions. Reference algorithms are also presented for the P (performance) and M (measurement) class PMUs. In this paper, the performance of these algorithms is analysed during some key signal scenarios, particularly those of off-nominal frequency, frequency ramps, ...

This paper presents a novel algorithm for recovering missing data of phasor measurement units (PMUs). Due to the low-rank property of PMU data, missing measurement recovery can be formulated as a low-rank matrix-completion problem. Based on maximum-margin matrix factorization, we propose an efficient algorithm based on alternating direction method of multipliers (ADMM) for solving the matrix co...

background and objectives: evaluating the performance of clinical units is critical for effective managementof health settings. certain assessment of clinical variables for performance analysis is not always possible,calling for use of uncertainty theory. this study aimed to develop and evaluate an integrated independentcomponent analysis-fuzzy-data envelopment analysis approach to accurate the...

In recent years, the electrical substations are experiencing a rapid transition towards fully digital measurement infrastructure, in terms of data acquisition, storage and processing. The IEC Std 61850-9-2 defines format, also known as Sampled Value (SV), to be employed by instrument transformers, merging units, controller devices. this scenario, it is reasonable expect that Phasor Measurement ...

The problem of effective use Phasor Measurement Units (PMUs) to enhance power systems awareness and security is a topic key interest. central question solve how this new measurements reconstruct the state system. In paper we provide first solution (globally convergent) estimation multimachine equipped with PMUs described by fourth order flux-decay model. This work significant extension our prev...
