Due to voltage and current limitations, the PV hosting capacity has been significantly reduced. To enhance PV hosting capacity in low voltage distribution networks, this research provides a viable strategy based on voltage control and dynamic voltage control using reactive power control with two different types of compensation including onload tap changing transformers as well reactive power controller with coordinated voltage management. For testing of developed strategy, the IEEE 123 standard bus systems is used to evaluate the maximum hosting capacity of different buses present in low voltage distribution system then to enhance the hosting capacity of specific bus via regulation using online tap changing transformers and reactive power compensation. The presented strategy is sufficiently effective and capable of dynamically controlling the voltages of low voltage distribution system with penetration of PV system hence enhancing the PV hosting capacity of distribution system.","PeriodicalId":219188,"journal":{"name":"2022 Third International Conference on Latest trends in Electrical Engineering and Computing Technologies (INTELLECT)","volume":"205 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132347201","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}

In this process, to automatically diagnose the presence of OSA, a simple, fast, and low cost technique is proposed. In the proposed technique, discrete-Fourier-transform (DFT) is applied to the noise and artifacts free electrocardiograph (ECG) signal. The proposed technique is validated over 260 ECG signals from the PhysioNet database. It is found that compared to polysomnography, which study of sleep profile of a patient and is a long, disturbing, and costly technique, proposed technique performs much better. The accuracy, specificity, and sensitivity of the proposed technique is 98.56%, 97.89%, 99.26% respectively.","PeriodicalId":219188,"journal":{"name":"2022 Third International Conference on Latest trends in Electrical Engineering and Computing Technologies (INTELLECT)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124028384","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 field of communication systems and network earmarked UAVs for airborne communication, which provides better throughput, line of sight with economical and less laborious infrastructure. Distinguishing the pros of UAVs and its applications in communication system domain, this study is structured to focus specifically on UAVs as relays. In this study, we highlight the comprehensive details of applications like WSN, SWIPT and beam-forming that provide the support of UAVs as relays. Moreover, the challenging issues such as power limitations of UAVs, positioning of UAV relays and security concerns in UAV relaying are also exploited with several dimension. This research also taken into consideration the futuristic trends and work areas in which UAV relays can be deployed for optimal production of efficient throughput.","PeriodicalId":219188,"journal":{"name":"2022 Third International Conference on Latest trends in Electrical Engineering and Computing Technologies (INTELLECT)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129602690","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}
