Due to the greater complexity that these studies imply, different computational and mathematical strategies must be used. Therefore, the analysis of electrical systems that integrate alternative forms of generation is of interest, and, in turn, the study of the environmental impact that the integration of said forms of generation entails is also essential. In this paper, a solution to the Environmental Economic Dispatch problem is obtained, considering the integration of wind energy. The solution to the proposed mathematical models is carried out through a free software computing platform; this platform is Scilab. Test scenarios with thermal generation units and wind farms are analyzed. The results presented allow us to analyze the impact of the integration of wind energy in power generation, generation costs, and polluting emissions.","PeriodicalId":174166,"journal":{"name":"2021 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116273373","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}

Among spectral analysis, there are methods for feature extraction to find out an early detection considering a significant number of samples of leaves in different growing stages considering healthy leaves, leaves in germination stage of the fungus, the first symptoms and diseased leaves identified in a previous work. In this study, with multiple comparisons and statistical tests, the discrete wavelet and Fourier transforms are employed for the feature extraction of the spectral data. A total of 13 features based on wavelet and 17 features on Fourier transform have significant differences between powdery mildew levels. The decomposition of the spectral signatures by wavelet-based and frequency domain coefficients as features shows a promising base by the classification for plant disease detection in cucurbits plants.","PeriodicalId":174166,"journal":{"name":"2021 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122791734","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 design and selection of the main hardware components is explained. Moreover, the techniques for reducing stray inductances and EMI in the designing printed circuit board is given. For the design of the circuit board, local regulations for grid interconnection and international standards have been considered to obtain a safe and reliable electronic power cell. The developed hardware has been subjected to different tests by using a cost-effective digital system and AC electric motors as loads. Three VSIs topologies are evaluated: single-phase 2-level H-bridge VSI, three-phase 2-level VSI and a single-phase 5-level cascaded H-bridge VSI. Experimental results validate the theory and demonstrate an excellent performance, reliability, and high efficiency of the developed power cells for modular VSIs.","PeriodicalId":174166,"journal":{"name":"2021 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131516158","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}

Battery management systems control power flow based on load requirements and also on the knowledge of the state of the battery. The state of the battery is determined by variables such as the state of charge, the state of health and the state of operation. However, since they are internal states that can only be estimated from external variables such as the current and voltage of the battery, it is necessary to carry out an identification of the parameters of a given battery based, for example, on an equivalent electrical circuit model or of other type. Model parameters can be obtained using various identification methods. This paper reviews some of the most common methodologies which are found in the specialized literature for the identification of the parameters of the battery model and their main features are compared.","PeriodicalId":174166,"journal":{"name":"2021 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"302 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123468727","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}
