A discrete model that is feasible to implement in an FPGA to achieve HIL simulation in real time is shown. An optimized strategy of implementation of nonlinear functions implemented in lookup tables is presented. That strategy allows optimizing the resolution without affecting the calculation latency. A latency analysis of the calculation of the model states is also included where a time of 100ns is established for each simulation step. This latency time is sufficient for real-time simulations. Finally, comparisons of results with a software-based simulator to validates the proposed model are shown.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10738270","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142555116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an alternative, ground camera approaches offer a low-cost solution; however, most of these methods use raw images from the water stream and are sensitive to environmental factors. We address this gap with a dataset comprising a visual marker with black bars indicating the water level, which we refer to as \"barcode panel\". We employed various deep learning algorithms to predict the water level and compared their performance. The proposed approach was evaluated using classic classification and error metrics. The models demonstrated accuracy in detecting the water level.

This work presents the design and implementation of a novel isotropic electric field sensor made with low-cost materials and processes. The response of the developed sensor was compared with the response of a commercial probe in order to perform calibration. The calibration methodology proposed in this work allows transforming voltage measured with the developed low-cost probe to electric field values measured with a calibrated commercial probe in order to calculate SAR values. The results show that the developed sensor can be used in SAR measurement processes.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10738269","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brazil is a big consumer of liquefied natural gas (LNG), while Morocco is a big fossil fuel importer. This dependence not only entails substantial import costs for Morocco and high NG liquefaction and transportation expenses for Brazil, but also contributes to elevated carbon emissions. Consequently, Brazil and Morocco are actively exploring substitute resources of renewable power to decrease their dependence on natural fuels and align with global renewable energy targets, including those set forth in agreements like the Kyoto Protocol. Brazil and Morocco boast an abundant array of renewable energy resources, including wind, hydro, solar, and biomass. Leveraging these resources has the potential to swiftly propel these countries towards a low-carbon emissions status when harnessed sustainably for electric power generation. Instead of relying on fossil fuels, the focus of this study is on tapping into the significant potential for power and electricity generation from agricultural residues in Morocco, giving the lessons to Brazilian energy sector for power and electric energy generation form ample agricultural biomass within Brazil. The results show a high potential for energy and electricity generation from cereals, olive biomass, citrus, and date palm residues in Morocco, while cereals, citrus, and sugarcane have better potential for bioenergy and electricity generation in Brazil.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10735448","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142517912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paraguay and Morocco are noted to derive the greater share of their energy from fossil fuel imports. However, the high import bills and carbon emissions, as well as the depleting nature of fossil resources have compelled these countries to seek sustainable power sources. Bioenergy from agricultural residues is an example of such sources due to the high agricultural production in Paraguay and Morocco. Therefore, in this study, the potential of electric energy generation from the biomass of three different varieties of Bertoni namely; Gawi, SugHigh3, and Pop in rural regions of Morocco has been analyzed. The analysis showed that the capacity of the electricity generation from stevia biomass for the different regions considered in the study ranged from 421.2 to 16865 W/ha, while the leaf yield and HHV variation for the different varieties ranged between 2.15 t/ha and 7.86 t/ha, and 21.24 MJ/kg and 27.83 MJ/kg, respectively. By considering a 1.66-kW biogas generator with operating hours of 8761 per year and LHV of 26.436 MJ/kg, as well as gasification ratio of 0.7 and 63.1% carbon content for HOMER simulation, a total capacity of 6.64 MW is suggested for installation in Tazuta. The findings indicate that Bertonis dry leaves are excellent biomass resources for energy production in rural regions of Berkane, Larache, Marrakech, Rabat, and Sefrou and they can give us good lessons for rural electrification of Paraguay.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10735445","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142517913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This topology shows the enhancement in the steady-state performance by reducing flux and torque ripples and minimizing the percentage of total harmonic distortion (%THD) in stator current. The FCS-MPTC scheme proposed here employs a shared DC link for both inverters, ensuring zero common mode current, thereby eliminating the need for a large isolation transformer. This topology generates Synthetic voltage vectors (SVV) which result from the vector summation of the individual inverter virtual voltage vectors. Common Mode Voltage (CMV) across the motor windings is nullified using this topology. Another notable aspect of FCS-MPTC is its ability to suppress high harmonic currents through the windings by reducing the average voltage in the non-torque-producing plane (x-y plane).
