The online estimated rotor resistance is updated in the IFOC operation by carefully observing the dynamics of the EV. In general, EVs operate in the flux saturation region to achieve higher gradients as well as the compactness of the overall drive system. The saturated flux operation of an induction motor has a variable magnetizing inductance profile depending on the level of saturation. The proposed Q-MRAC considers the complete magnetizing inductance variation profile to estimate an accurate value of rotor resistance, and updates into the IFOC algorithm without affecting the vehicle dynamics. The proposed controller makes the EV drive system more efficient. This estimation works accurately at all magnetization levels and stator frequencies. The simulation results validate the effectiveness of the proposed estimation technique.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130191060","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}

Networks are operated at their peak capacity to meet the demand. These circumstances forced the operators to opt for Wide Area Measurements and Control (WAMC) schemes for real-time monitoring, control, and protection. Synchrophaosr technology has evolved as a promising technology for the implementation of WAMC. Phasor Measurement Units (PMUs) can provide the synchrophasor data along with frequency and Rate of Change of Frequency (ROCOF). Whereas the deployment of these devices was limited due to higher price tags. This constraint has been dealt with in this study by identifying the optimal locations for PMU placement considering the measurement redundancy.In the present study, the optimal PMU placement problem is formulated using binary decision variables (1,0) representing the existence or non-existence of PMU at that bus. Initially, an additive algorithm to solve linear problems with binary decision variables, Balas additive algorithm (BAA) is tested to solve the optimal PMU placement problem. After understanding the challenges a nature-inspired algorithm, Binary Particle Swarm Optimization (BPSO) technique is used to solve the problem. While maintaining the complete system observability, the presence of Zero Injection Busses (ZIB) is also exploited to reduce the count of PMUs. Consequences of optimal placement problem (OPP) like, measurement reliability is also addressed considering redundancy in measurements. Finally, the existence of multiple solutions was solved by introducing Bus Observability Index (BOI) and the System Observability Redundancy Index (SORI) rankings. Algorithms are tested on standard IEEE systems. Results have shown, less than 25% of the busses demanded PMU placement for full system observability, at the same time the number of installations increased with measurement redundancy.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133210108","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}

The square spiral coils are easier to implement than the circular ones. In this paper, a new analytical calculation for magnetic flux density of the spiral coils is presented, which is simpler than the greenhouse method. This paper presents a comparative study of the magnetic field distribution for circular and square coils. The magnetic flux density is obtained using the Biot- Savart’s law, furthermore a detailed analysis is performed in order to obtain simple mathematical expressions that relate the area, with uniform magnetic field, to the length of the different coils and number turns of the coils. Two adaptations of the Biot- Savart’s law are developed in this paper which offer a means of calculating the flux density given the position of interest, the coil geometry, and the amount current passing through the coil. The calculation of the magnetic flux density using analytical formulas and finite element simulations are compared. Finally, a cube volume of uniform magnetic field in each coil is calculated. In this paper magnetic flux densities are determined for different currents at various locations for circular coil as well as square coil. Computational models are constructed and simulated using ANSYSS Maxwell software in order to validate the calculated results of the magnetic field distribution of each geometry considering similar parameters.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"608 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134545406","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 detailed investigation is carried out under three different cases for RTPV deployment at each load node as 1) fixed rating per phase; 2) rating proportional to the load at each node; 3) optimum rating obtained using an optimization algorithm. The objectives considered for the optimal selection of RTPV ratings are energy loss minimization and voltage unbalance across three phases apart from active and reactive power optimization. The RTPV systems are operated under volt-VAR control, to achieve the optimum power quality along with minimum losses. The network selected for the above study is IEEE 13 bus system so that the impact on each line and load is monitored. After analysis of the obtained results of 13 bus system, further investigation is carried out for IEEE 8500 node network to validate the proposed concepts.

For these applications, transformers play an important role in facilitating galvanic isolation and suitable voltage ratio for interconnection between grid and inverter. However, the omitting of the transformers from the complete power conversion system becomes inevitable because of having large size/weight and cost. Hence transformerless inverters are replacing conventional inverters for grid-connected PV systems at a rapid pace. It has been observed that a transformerless grid-connected H bridge inverter established a common mode resonant circuit with the formation of parasitic capacitance between PV terminals and grounded frame and hence, consequently, leakage current induced in the system. In this paper, a mathematical model has been derived by using source transformation approach for the common-mode resonant circuit of H bridge grid-connected PV inverter, and further, it has been analyzed for both unipolar and bipolar modulation strategies. Finally, a 1kW grid-connected single-phase H bridge PV inverter has been simulated on Matlab and verified with satisfactory results.","PeriodicalId":232560,"journal":{"name":"2021 International Conference on Sustainable Energy and Future Electric Transportation (SEFET)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124109813","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}
