This study was carried out using various quantities of biogas, to analyze the main pollutants released by the engine at the end of the combustion process, according to the quantities of biogas that enter the engine. The results we obtained when carrying out the theoretical study show us that increasing the amounts of methane favors the behavior of the engine in various conditions, on the contrary, increasing methane and reducing CO2 increases the concentrations of pollutants such as CO, SO2. Biogas has been implemented as an alternative fuel, highlighting its positive impact on energy sustainability and the reduction of operating costs. Finally, we analyze that biogas has great potential to contribute to a cleaner and more sustainable energy future if current barriers are overcome.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"23 5","pages":"397-404"},"PeriodicalIF":1.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10974370","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860805","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}

In this context, collaboration among NIDS improves intrusion detection by sharing information about local threats. However, most current solutions neglect the reliability and robustness assessment of these systems, especially when we consider C-NIDS. Thus, the lack of standardized and robust assessments to measure the reliability and accuracy of C-NIDS in attacks detection results in significant uncertainties regarding their ability to correctly identify threats. In this paper, we present an evaluation of a collaborative NIDS that integrates standalone NIDS to share information about detected and mitigated threats, improving overall intrusion detection. The evaluation took place in a virtualized IoT environment and results showed that collaborative NIDS detected DDoS attacks with an accuracy of at least 99.94%, a minimum recall of 99.94%, a precision of 100%, and F1 score of 1 in all evaluated scenarios. Such results highlight the development and adoption of uniform evaluation criteria to ensure the effectiveness and reliability of C-NIDS.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"23 5","pages":"363-370"},"PeriodicalIF":1.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10974426","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860807","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}

RES aggregators compete to increase their profit but their intermittent nature adds financial risks to aggregators (As). The main objective of this paper is to model a day-ahead electricity market by considering RES aggregators as participants to trade energy effectively to maintain a dynamic energy balance. Instead of relying on existing probabilistic forecast methods to account for the variable uncertain nature of RES, this paper uses a novel data-driven forecasting method to predict variable RES power generation accurately. The proposed model follows a three stage approach. The first stage involves forecasting PV and wind output power with multiple scenarios. In the second stage, a scenario-based multi-aggregator market modelling is performed where aggregators submit their bids to the distribution network operator, who then clears the market by generating price signals. Uncertainties of RES aggregators lead to financial risk for aggregators. Hence, the third stage involves, risk assessment using value at risk (VaR) and conditional value at risk (CVaR) are applied to different scenarios for evaluating the potential portfolio losses within a specified time horizon and confidence level. To evaluate the effectiveness of the proposed model, it is tested on a modified 33-bus test system which shows effective energy trading at a distribution system with a considerable marginal range of voltage violations. The proposed novel three-stage model aims to improve the distribution level electricity markets efficiency and reliability, benefiting RES market participants and consumers alike.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"23 5","pages":"415-426"},"PeriodicalIF":1.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10974375","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860808","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}

Copper Zinc Tin Sulfide (CZTS) has emerged as a promising absorber material due to its exceptional light absorption coefficient and the abundance and non-toxic nature of its constituent elements. This study leverages SCAPS-1D to investigate the working mechanism of CZTS-based solar cells. We simulate a Mo/CZTS/CdS/ZnO device structure under AM 1.5 spectrum illumination and 300 K temperature, analyzing the impact of individual layer thickness on photovoltaic performance. Further, a comparative analysis explores the influence of various n-type materials.. In addition, the introduction of antimony (Sb) doping into CZTS leads to a significant change in efficiency of the cell. The efficiency of Sbdoping CZTS attained 21.90%, while there was a great improvement by 3% via reduced recombination losses and enhanced photocurrent. This work gives an insight into the possibility of Sb doping for the improvement in the performance of thin-film solar cells.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"23 5","pages":"380-386"},"PeriodicalIF":1.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10974365","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860804","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}

The complex nature of wind necessitates advanced data analysis techniques to extract meaningful patterns from meteorological datasets. This study presents a stochastic wind classification and identification analysis based on a Gaussian Mixture Model (GMM) clustering method applied to a case study in La Rumorosa'', Mexican California. By analyzing four meteorological variables (relative humidity, atmospheric pressure, wind speed, and wind direction) over five years, the method automatically identifies distinct wind conditions that can be defined as climate states, including well-known regional phenomena like Santa Ana winds and local orographic winds. Accurate detection of wind states enables better forecasting of wind energy potential at favorable sites, wildfire risk management through predicted fire behavior and monitoring pollutant/allergen dispersal patterns. The proposed approach offers a reliable, computationally efficient method for detecting wind patterns, extending to different geographical regions impacted by diverse wind phenomena.","PeriodicalId":55024,"journal":{"name":"IEEE Latin America Transactions","volume":"23 5","pages":"387-396"},"PeriodicalIF":1.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10974369","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860838","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}
