In comparison with the conventional buck-boost converter, this topology has continuous input and output current waveforms, being so beneficial when it comes to real-world applications. The proposed converter, additionally, is common-grounded, meaning that the polarity of the input voltage is the same as the polarity of the output voltage. Regarding the voltage and current stresses, the suggested converter has better performance in comparison with the structures having nearly the same conversion ratio, and this results in having semiconductor devices with lower on-resistance and, accordingly, lower conduction losses. The operating principle, design procedure, comparison with the other related topologies, and efficiency analysis are separately investigated and discussed. Eventually, to confirm the validity of the introduced converter, the simulation results are compared with the theoretically calculated values.","PeriodicalId":438265,"journal":{"name":"2022 12th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123697937","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}

Aiming at the communication optimization problem of DR wireless communication, this paper designs a double-layer adaptive coding strategy based on real-time monitoring of signal-to-noise ratio and real-time acquisition of broadcast messages from DR master station on the premise of analyzing the quality of service requirements of all kinds of DR services. The proposed strategy uses adaptive precoding technology to optimize DR wireless communication, classifies the communication quality of service according to the specific period of time during the implementation of DR, and considers the computational cost introduced by the algorithm. The simulation results show that the strategy has a good optimization effect in the system bit error rate and processing delay control.","PeriodicalId":438265,"journal":{"name":"2022 12th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131973085","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}

Yet, fuel cells are susceptible to operating conditions and hydrogen impurities, leading to performance loss over time in service. Hence, performance degradation prediction is gaining attention recently for fuel cell system reliability. In this work, we present a knowledge transfer approach for online voltage drop prediction. A dual-path convolution neural network is proposed to extract linearity and non-linearity from historical data and performs multi-steps ahead prediction with uncertainty quantification. Online voltage prediction is then evaluated with and without knowledge transfer using two different PEMFC datasets. Results indicate that our proposed approach with transfer knowledge can predict the voltage drop accurately with a small uncertainty range compared to the conventional approach.","PeriodicalId":438265,"journal":{"name":"2022 12th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133698972","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 Ce-doped YAG phosphor particles of 15-20 µm are separated via conventional filtration method and mixed with different concentrations (0.3%, 0.5%, 0.8%, and 1%) in ethylene-vinyl acetate (EVA) to make luminescent DS films, which is used for packaging the polycrystalline silicon (pc-Si) solar cells. The photoluminescent intensity of YAG: Ce particles, the transmission of luminescent DS films with different concentrations, and the performance of packaged solar cells have been analyzed. Experimental results show that a higher concentration of phosphor particles in EVA raises the surface reflection, which negatively influences the solar cell’s performance. When the particles range is fixed (15-20 µm), the luminescent DS films with the mass ratio of phosphors to EVA 10:0.03 have the highest transmission. The biggest improvement in the conversion efficiency of solar cells after packaging is due to the 10:0.08 mass ratio of phosphor in EVA.

Data-driven approach is a newly proposed technology, unlike traditional model-driven power flow calculations, it can bypass circuit parameters and environmental variables to obtain results from global bus data. However, with the development of renewable energy, more complex power grids make it difficult to obtain complete data and reduce performance. Therefore, this paper proposes a method of estimating power from incomplete bus data. The method is based on a modified data-driven power flow model, and its core is to derive and induce a regressive model through the physical model. The simulation results on IEEE standard bus 30 show that this method has higher accuracy than other models in incomplete bus data power estimation.","PeriodicalId":438265,"journal":{"name":"2022 12th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132062789","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}
