Abstract One challenge in Wide Area Measurement System is to design a reliable network which assures data availability. The availability of Phasor Unit (PMU) networks depends on two factors: 1‐Reliable measurements depend performance PMUs and transmission branches, 2‐Reliable the reliability communication used transfer from Data Concentrators (PDCs) control centre. can be improved by choosing p...

Timely remote activation of frequency response, provided by converter-based generation, can improve the damping very low-frequency (VLF) oscillations. The research presented is based on both power system models and actual data from phasor measurement units (PMU) Irish system. performance active control (APC) investigated, variations in wind speed, droop, time lag resource capacity demonstrate t...

Evaporation is one of the largest water losses from most of the dam lakes in Iran. Estimating the evaporation rate enables us to apply the proper evaporation mitigation technologies. In this study, the feasibility of different evaporation estimation methods was studied to find an optimum method with a fair tradeoff between cost and accuracy. The optimum method may vary depending on the climate....

In this paper it is shown that M class PMU (Phasor Measurement Unit) reference model for phasor estimation recommended by the IEEE Standard C37.118.1 with the Amendment 1 is not compliant with the Standard. The reference filter preserves only the limits for TVE (total vector error), and exceeds FE (frequency error) and RFE (rate of frequency error) limits. As a remedy we propose new filters for...

In this paper, a methodology for designing an optimal monitoring architecture by using a limited number of PMU (Phasor Measurement Units) and a PDC (Phase Data Concentrator) is proposed. The optimal design problem consists in defining the optimal location of both the PMU and the PDC by maximizing the expected value of the trace of the observability gramian of the power system over a large numbe...

Load modeling has a significant influence on power system analysis and control. In recent years, measurement-based load modeling has been widely practiced. In the load modeling algorithm, the model structure is determined and the parameters of the established model are estimated. For parameter estimation, least-squares optimization method is applied. The model parameters are estimated so that t...

This paper presents a new framework of identifying a series of cyber data attacks on power system synchrophasor measurements. We focus on detecting “unobservable” cyber data attacks that cannot be detected by any existing method that purely relies on measurements received at one time instant. Leveraging the approximate low-rank property of phasor measurement unit (PMU) data, we formulate the id...

Microbial fuel cells (MFC’s) are promising energy harvesters to constantly supply energy to sensors deployed in aquatic environments where solar, thermal and vibration sources are inadequate. In order to show the ready-to-use MFC potential as energy scavengers, this paper presents the association of a durable benthic MFC with a few dollars of commercially-available power management units (PMU’s...

Catastrophic failures in power grid due to maloperation of traditional backup protection system (e.g. third zone of distance relays) was one of the main causes of many cascade trips. This paper assess a new wide-area backup protection system (WABPS) based on phasor measurement units (PMU), to improve third zone of distance relays to avoid its mal-operation. Based on this assessment, phasor meas...
