“…Whenever fault appears in the system, the wide-area security system uses the online measurement data to discover the faulty buses and, consequently, the faulted line to isolate it from the rest of the system. They play a significant role in modern power system studies; the crucial ones are discussed in the following subsections [14,15].…”

The complexity and dynamics of the modern power system are continuously changing due to the penetration of a large number of renewable energy sources and changing load patterns. These growing complexities have caused numerous outages around the world, primarily due to the lack of situational awareness about the grid operating states. Rectification of this problem requires advanced sensing technology to accurately capture the dynamics of the system for better monitoring and control. Measurement of synchrophasors is a potential solution to improve situational awareness in the grid. The synchrophasors technology is now widely accepted throughout the world and has the potential to replace the existing SCADA system in monitoring and control of the power system. Their installation enables efficient resolution to substantially improve transmission system planning, maintenance, operation, and energy trading. This paper reviews the state of the art potential applications that the PMU based WAMC offers to the power system. It also includes technical perspectives, challenges, and future possibilities.

“…For comparison, other two commonly used or stateof-the-art algorithms, i.e., weighted TLS (TWLS) [25] and i-IpDFT [2] are also tested. The TWLS algorithm uses the Blackman window function with good sidelobe attenuation [26] and the i-IpDFT applies Hanning window function [2] having maximum sidelobe decay within two-term cosine windows.…”

The increasing use of renewable generation, power electronic devices, and nonlinear loads in power systems brings more severe interharmonic tones to the measurand, which can increase estimation errors of P-class PMUs, cause misoperation of protection relays, and even threaten the stability of the power systems. Therefore, the performance of the P-class synchrophasor estimator under interharmonic interference should be evaluated and new estimation schemes that can improve the operational robustness are needed for various protection and control applications. In this paper, a synchrophasor estimator design for P-class PMUs that introduces singular value decomposition to the least square algorithm based on the Taylor series is proposed. By constructing an optimization with proposed adjustable parameters, finite impulse response filters with high transition band attenuation are designed. Numerical and experimental tests verify the proposed dynamic synchrophasor estimator performance and show an effective improvement in rejecting interharmonic tones, especially when a short time window and light computational burden are required.

“…3. All of these measurements are synchronized through the GPS base timing to complete the picture of the functioning electricity grid [9]- [11]. The data in each PMU is time-synchronized via Global Positioning System (GPS) receiversto an accuracy of one microsecond and aggregated in the Phasor Data Concentrator (PDC) several times a second according to IEEE C37.118 for WAMS solutions.…”

The worldwide outbreak due to COVID-19 pandemic lead to a major change in the life style in general and in the education system in specific. To help contain the impacts of COVID-19, universities and schools need to strongly shift to various electronic education models such as online learning, distance learning and blended learning. One of the crucial models that support the success of distance learning especially in engineering education is the remote-controlled experimentations, which allow students to execute the required practical work in a similar way as it conducted in the physical laboratories if it is appropriately designed. This paper introduces an integrated solution for improving the remotely controlled working on the educational laboratory experiments for electrical engineering sector. The proposed solution consists of four main components: Internet of remote-controlled things that represent the required experimentation devices, cloud platform, TCP/IP Internet communication connection, and finally the control and monitoring application. A complete experiment for phasor measurement unit (PMU) system as an example is deployed in the university laboratory with its all components which is completely controlled and managed remotely from the home through Internet. PMU is installed in a prototype of electrical substation with different types of loads. All required experimental data and results are successfully obtained and controlled through the developed system with the required accuracy and performance.
