This article suggests the CMPN-LMSRE-based HAFA because of its quick convergence, low computing load, and straightforward construction. Through quick convergence velocity, the proposed HAFA adjusts the gains of all proportional-integral (PI) controllers. Under the cascaded arrangement, four PI controllers are used in the rotor side converter (RSC), and four more are used in the grid side converter (GSC). The RSC is regulated by cascaded structure-based PI controllers to limit generator power loss and enhance power production. In contrast, GSC is controlled to preserve the grid side reactive power and dc-link voltage. By contrasting the outcomes of the proposed CMPN-LMSRE-based PI controllers with those of CMPN-based and LMSRE-based PI controllers during severe grid disturbances, the validity of the proposed CMPN-LMSRE-based PI controllers is confirmed. The MATLAB application is used to carry out the LVRT capability.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124685592","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}

Wind speed depends on many variables such as temperature, pressure, humidity, and other lower atmospheric conditions, and thus mathematical modeling is highly complex and requires high computational power and time for wind speed prediction. Over the years, data-driven models for multi-step ahead time-series predictions have been gaining attention and are still in the evolutionary stage. Improvements in prediction models help the wind generation systems to operate efficiently. The accumulation of errors in the multi-step prediction creates a challenge in formulating novel prediction models. A prediction model based on long short-term memory (LSTM) is proposed in this study for short-term wind prediction up to a prediction horizon of 3 hours ahead. Hyperparameters of the LSTM model are tuned by Bayesian optimization. The wind speed data of two different sites are considered for the evaluation of the proposed model. Further, Support vector Regression based on the Multiple Input Multiple Output (MIMO) strategy is used to compare the performance of the proposed model. Bayesian optimized Long Short Term Memory (BO-LSTM) model shows nearly 30% and 16 % improvement in the MSE and RMSE scores, respectively, over the SVR model.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121774334","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}

With reference to the authenticated sources, around 65% Indian inscriptions were found in Tamil language. Amidst many inscriptions character recognition studies that have been published for different languages, no significant effort has been taken for Tamil language. There are few high performances online Handwritten Tamil OCRs for modern Tamil alphabets, but they perform with less than 20% accuracy while dealing stone inscription characters since the alphabets are of ancient form and also the difference between background and foreground is very meager in stone inscriptions. Most of the existing character recognition studies for Handwritten Tamil scripts have relied upon the widely used Hidden Markov Model (HMM), in spite of its familiar shortcomings and few reported in ANN. Though character recognition from the images of inscribed documents is challenging because of the complex character structure of the Tamil language scripts and other artifacts like aging and degradation, modern techniques needs to be developed to digitize such inscriptions and preserves them as electronic documents. In this paper, a novel approach is proposed for recognizing the inscription characters from the ancient Tamil stone inscriptions based on two recently developed models of Convolutional Neural Networks and Recurrent Neural Network (RNN). Camera captured stone inscriptions script images are taken as input and enhanced for clarity through various image enhancement techniques like filtering, luminous, erosion, dilation and blurring. Project profile based character segmentation is done for extracting individual characters out of script image. Over segmentation reduction is done for eliminating touching and broken characters. The character recognition is done in twofold. (i) Recognition of single characters (vowels and consonants) using Convolutional Neural Network (ii) Recognition of compound characters using Recurrent Neural Networks-BLSTM model. A meticulous test on large datasets has been performed to evaluate the performance of the proposed approach. Experimental results show that the proposed CNN based system achieved training accuracy of 88% and validation accuracy of 94% is obtained (Included RNN accuracy). The system performance is evaluated on various test cases in each phase and the limitations have been identified.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116684660","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}

Quarantined subjects were monitored manually, and patients tended to abscond or “run away.” In the Philippines, there was a lack of research and the absence of similar technology commercially available related to this matter. Project Bantay integrated Artificial Intelligence of Things (AIoT), indoor positioning systems, and wearable technology to alleviate the shortage of personnel, long-term savings on workforce utilization in the government, and predict absconding or “run-away” potentially infectious individuals in our current and future quarantine facilities. Also, it included information system development for monitoring quarantined subjects' heart rates and temperatures that would eventually help the government combat and prepare for a similar unexpected pandemic. The prototype would start by turning on the device after being placed on the quarantined subject. The device must be linked to the router, and the sensors must then be calibrated. The web interface should receive and be able to see data readings, including temperature, heart rate, the location of the subject being quarantined, and the removal of the device via an IR reading. The temperature, heart rate sensor, and indoor positioning all measured above a p-value of 0.05, which accepted the null hypothesis, confirming that the actual and commercial product versus Project Bantay's temperature, heart rate, and indoor positioning accuracy was statistically the same. The anti-absconding tendencies of the hypothetical dataset using machine learning data analytics showed that among four inherently multioutput machine learning regression algorithms, the Decision Tree Regression Algorithm could output a much better result in determining the tendencies of a subject to abscond from the quarantine facility.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132750931","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}
