They must meet accuracy, security, and reliability. Hence, these sensors become sophisticated and expensive. This paper proposes a transducer not only to meet charge electricity billing, but also to acquire waveforms to evaluate adverse power quality phenomena. The proposed transducer is based on an optocoupler to isolate the electrical network from the meter. The transducer design uses a suggested method to exploit properly the current transfer ratio to meet the accuracy and linearity needed in the power quality context. In addition, a method to estimate a correction factor to compensate for the tolerance in the component values of the transducer is given. The proposed transducer has been validated using Oread Lite® software to simulate different case studies related to power quality phenomena. Results show that the proposed transducer has an adequate performance for smart electricity meters that can be extended to evaluate adverse power quality phenomena.","PeriodicalId":237392,"journal":{"name":"2022 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125879036","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}

By implementing a Raspberry-based Low-resolution embedded system based and a FLIR Lepton® sensor human body temperature is measured and improved by four different algorithms implemented. Firstly, three traditional time-series processes solving such as, Simple Mean (SM), Simple Moving Average (SMA), and Multi Lineal Regression (MLR), and secondly, and online filter-based Kalman predictor were implemented to increase the signal to noise ratio of the acquired temperature magnitude. Results of average prediction for different benchmarks demonstrate the best performance of Kalman Filter upon traditional processes. In addition, this algorithm achieves to smooth output temperature with fewer samples (∼10% of total samples) in comparison MLR and SMA.

However, the oscillatory trends and the non-linear dynamic behaviour of the system measurements in the first seconds of the transient period often mislead the appropriate knowledge of the actual coherent groups, making wide-area coherency monitoring a challenging task. Inspired by swarm behavior in nature, we propose a modified Particle Swarm Optimization (PSO) approach based on centroids codification to identify coherency within a short observation window. A user-defined inter-group function is proposed and compared with conventional intra-group functions to examine the quality of the compacting and separating features of the final clusters. To demonstrate the effectiveness of our technique, we clustered the highly nonlinear dynamic responses of the generators on the 39-bus New England system. A comparison with other clustering methods was carried out to highlight the strength of the proposed algorithm.","PeriodicalId":237392,"journal":{"name":"2022 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115374498","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}

Moreover, passive elements also produce power losses that reduce the efficiency. In general, the power losses vary along with the variations of the irradiance, thus, at low power, the efficiency is low while at rated power the efficiency is maximum. In order to increase the efficiency during low irradiance intervals, this paper proposes a method to improve the efficiency in a photovoltaic inverter by means of the implementation of a hybrid MOSFET-IGBT switch which has been implemented for the H5 topology. The proposed solution consists in the use of a MOSFET and an IGBT connected in parallel. The main idea is to take advantage of the lower losses of a MOSFET in low power and the lower losses of an IGBT in high power. The proposed idea is validated by means of simulations, demonstrating the feasibility of the hybrid switches. The results show an improvement in the European efficiency and the California Energy Commission (CEC) efficiency, in this case is the European efficiency where the improvement is higher, however the behavior of the results indicate the hybrid switch can achieve a higher efficiency with a higher power if it is compare with the using of only MOSFET or only IGBT.","PeriodicalId":237392,"journal":{"name":"2022 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125859795","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}
