These assumptions can still present consistent results and a considerable computational advantage for the design of machines and other assessments under normal operating conditions. However, it can be observed that FEM is still hardly used in modeling and diagnosis of motors failures, even with coherent and promising results. In some failure situations, it can be highlighted that some typical geometric conditions of simplification may cease to exist, which makes the 3-D models more comprehensive and representative under these circumstances. Thus, the present work aims to contribute to development of fault diagnosis field in induction motors, pointing out the possibility of implementing three-dimensional FEM models to simulate faulty motors. Furthermore, it intends to demonstrate that, although complex and almost underexplored, faulty motors 3-D modeling is viable, promising and has significant advantages over 2-D.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"2019 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131765783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Weibull model is examined and calculated with a modified maximum likelihood method approach. Simulation case studies on nineteen turbines have been validated for the probability of wind speeds in the rated region, cut-out regions, and unrated region, in addition to other simulation conditions such as annual energy production and capacity factor. Based on the wind distribution, selected turbines have been evaluated for optimal, sufficient, and insufficient rated wind speeds. Simulation results show higher rated turbines can under-perform those of lower rated capacities. Efficiency and production correlate closely with optimization of rated wind speeds.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132865016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These current harmonic components cause a nonlinear voltage drop across the grid impedance leading to considerable distortions in the voltage. These harmonic distortions jeopardize the operational performance of adjacent linear loads coupled at the point of connection. Therefore, to remediate the various Power Quality (PQ) issues posed by nonlinear loads, this article proposes an Advanced Shrinkage Normalized Sign (ASNS) based control architecture for Photovoltaic (PV) inverter controlled PQ conditioner. More precisely, the proposed ASNS scheme is intrinsically responsible for decomposing the fundamental weight components of the load currents from harmonically adulterated currents. Besides active power injection into the established grid, ASNS is required to serve the following distinctive control objectives under weak distribution network: (i) Active compensation of nonlinearity introduced by the PV array; (ii) Grid current balancing; (iii) Harmonic and reactive current compensations, and (iv) Power factor correction. Furthermore, all the theoretical developments are examined through numerical simulations in MATLAB/Simulink environment using SimPowerSystems toolbox. In summary, the tests results substantiate the effectiveness of the ASNS architecture to operate seamlessly even under adverse grid scenarios and thereby improving PQ.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"244 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123158936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It leverages eye-tracking and other biosensing devices in simulated power system operations to capture critical human behavior data that can be further analyzed to extract qualitative and quantitative metrics in defining grid situation awareness.

The MPC dynamically adjusts the setpoints of existing primary controls to maximize system stability. To address the computational challenges of a real-time MPC implementation due to nonlinear power system dynamics and short sampling intervals, a trajectory linearization technique is applied to the MPC formulation. The proposed controller is validated on a notional industrial microgrid for a variety of disturbances.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"11 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133085068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the ac side of GSC, Nyquist-based stability analyses are typically performed due to the presence of multiple eigen-loci. However, DC side Nyquist stability criteria lead to computing the input admittance at the ac side of GSC. This input admittance behaves as a negative incremental for the CPL operation of the connected induction motor load; thus leads to voltage instability at the load bus. This paper also addresses the voltage stability issue corresponding to double-circuit line failure. This analysis is conducted through detailed impedance modelling of the system. The feasibility of designing a phase-locked loop (PLL) for such a scenario of grid disturbances are investigated in this paper through MATLAB/Simulink environment.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131084753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such a scenario is significantly challenging in the sense of providing reliable supply of power to CI units. In this article, an intelligent optimization scheme, termed a horizon of viability (HoV) engine, is developed to guarantee the viability of a sustained, reliable supply of power to the CI units over a time horizon. The proposed HoV engine generates a cost-optimal portfolio of the locally available generation sources and the loads over a time horizon using a mixed-integer convex programming problem. A controller-hardware-in-the-loop (CHIL) platform is developed to evaluate the control performance of the HoV engine. The experimental results corroborate the efficacy in maintaining the viability of the CI units after a grid interruption event. Further, the proposed HoV optimization scheme performs better than existing net-load management schemes in the literature.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131117322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For traditional half-bridge gate driving circuits, inserting a series capacitor between power switches of phase A increases loop parasitic inductance, introduces a time delay mismatch between the gate voltages of the two switches, and causes interference with the synchronization of the deadtime between phase A&B of 2-pscB converters since phase B has no series capacitor. Using traditional half-bridge gate driving circuits in 2-pscB, the turn-off delay of phase A switches caused by its CDS discharging period appears and amplifies by parasitic effects and the phases' sinking path mismatch. This will eventually result in almost no deadtime conduction. In this paper, a lab prototype using a commercial EPC half-bridge GaN-based circuit has been designed and tested to investigate the deadtime mismatch and the behavior of CSM in the traditional isolated gate driving system.","PeriodicalId":245119,"journal":{"name":"2022 IEEE Power and Energy Conference at Illinois (PECI)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126504773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
