Linear State Estimator (LSE) technology has been implemented and deployed at system level. However, the benefit of this new technology has not been very well explored at substation level. This paper proposes to use the LSE technology for detecting anomalies in synchrophasor measurements, and further assisting with substation equipment health monitoring, by leveraging substation model and built-in bad data detection and identification module to probe if there is the anomaly of either equipment status or topology error. Data-driven statistical anomaly detection methods are also proposed in the paper to compliment the SLSE for substation secondary asset health monitoring. Case study demonstrates that proposed methods can identify measurement anomalies and monitor equipment health to reduce equipment failure rate and prevent the equipment outage.

A power system electromechanical wave propagates from the disturbance location to the rest of system, influencing various types of protections. In addition, since more power-electronics-interfaced generation and energy storage devices are being integrated into power systems, electromechanical wave propagation speeds in the future power systems are likely to change accordingly. In this paper, GPS-synchronized measurement data from a wide-area synchrophasor measurement system FNET/GridEye are used to analyze the characteristics of electromechanical wave propagation in the U.S. Eastern Interconnection (EI) system. Afterwards, high levels of photovoltaic (PV) penetration are modeled in the EI to investigate the influences of a typical power-electronics––interfaced resource on the electromechanical wave propagation speed.

Previous research on career readiness of engineering college students has mainly been focusing on profession required competencies. For engineers, career readiness contains a more fundamental, attitudinal domain that has not been explored thoroughly. The goal of this work in progress is to examine the changes in student attitudes toward careers in the power industry due to curriculum improvement made to bridge the gap between classroom and industry. A novel instructional design, the Power-Up Model, is proposed and now being implemented, which is expected to significantly increase student awareness of, efficacy in, and commitment to a career as a power engineer. The design of this model is based on the authors' experience in engineering education at minority-serving institutions. It holds promise to sustainably develop a diverse and well-prepared generation of power engineers and ultimately improve the nation's STEM workforce diversity.

The rapid evolution of the grid requires the need for new and innovate technologies to operate, construct and maintain electrical service. Traditional equipment and techniques are not timely, efficient or maintain reliability during replacement or upgrade of transmission. The deployment of temporary and mobile support for fast voltage mitigation and regulation is necessary.

A Provisional Microgrid (PMG) is a specific and promising type of microgrid that enhances the utilization of renewable energy resources in an efficient and cost-effective manner. The PMGs, however, must be electrically integrated to an existing microgrid, called a coupled microgrid (CMG), for islanded operation. This paper proposes a communicative optimal scheduling model in which the local power exchange between a PMG and a CMG is determined through iterative exchange of relevant information. The final solution will ensure a reduced load curtailment in PMG and a higher economic benefit for the CMG. The proposed model is mathematically formulated using mixed-integer programming, and studied through numerical simulations to show performance and effectiveness.

The application of current and voltage sensors in the electric power network is exhibiting considerable growth in the US. Several utilities have deployed large number of post insulator type current and voltage sensors on the distribution feeders for initiatives such as Volt-VAR Optimization (VVO) and Conservation Voltage Reduction (CVR). Due to the lack of a stand-alone standard for sensors in IEEE, every vendor has a slightly different way to test the accuracy of these sensors. Furthermore, we have noted a mismatch between single-phase test results in the laboratory and performance in actual 3-phase outdoor field installations. In this paper we explore the reasons for aforementioned performance gaps and propose specific additional tests that should be carried out to get a full understanding of the accuracy behavior of the sensors.

This paper proposes a fuzzy logic controlled thyristor switched capacitor (TSC) to improve the power quality of a hybrid network system consisting of one wind generator and two conventional synchronous generators. The performance of the proposed method is compared with that of the Proportional-Integral-Derivative (PID) controlled TSC. The effectiveness of the proposed method is evaluated by considering both balanced and unbalanced permanent faults in the system. Moreover, in order to demonstrate the effectiveness of the proposed approach, the voltage index associated with the point of common coupling (PCC) of the power network has been used. In addition, the power quality in terms of harmonic distortion has been evaluated at the PCC for both synchronous generators and wind generator. Simulations have been performed by using the Matlab/Simulink software. From the simulation results, it is clear that the proposed fuzzy logic controlled TSC method is effective in improving the power quality of the hybrid network system. In addition, the proposed fuzzy logic controlled TSC performs better than the conventional PID controlled TSC.

This paper introduces a machine learning approach for real-time battery optimal operation mode prediction in residential PV applications. First, from the historical data, the optimal battery operation mode for each operation interval is derived. Then, a best performing algorithm for the prediction of the optimal modes is obtained. Performances are tested with different number of features in the training test and different training lengths. Then, the features will be used to predict future operation mode in real-time operations. A comparison on bill savings is made with the model-predictive control approach using the residential load and PV data from the Pecan Street project website under the Hawaiian electricity rate. Simulation results show a 9 points improvement in performance.

The article reviews the newest developments and trends towards large power transformers for improving grid resiliency by using advance insulation systems allowing for smaller size, lower weight designs. Initially developed for mobile transformers and substations, the hybrid insulation system have to evolve to allow for larger units to be transformed easily and rapidly to areas with emergency situations. To achieve such compact designs, insulation systems have to be developed with new insulation components made out of high temperature materials.

A demand response (DR) application for improving a power system's heat rate is analysed and simulated. It is proposed that the short cyclical high amplitude load of the in situ arc furnaces be attenuated by the dynamic curtailment of selected grouped commercial air conditioning (AC) loads. A dynamic electrical demand model for the aggregate electrical demand of large, diverse population of air-conditioned buildings is formulated and analysed. For a fictitious test population of air conditioned buildings, the developed model is employed to demonstrate the possible effect on the system demand profile that could be realized by the proposed DR strategy. Electrical energy production simulations are performed to quantify the improvement in average system heat rate and thus the reduction in energy production cost that would be achieved by the strategy.
