Over last year, many methods are based on non-destructive tests such as Line Resonance Analysis (LIRA), Broadband Impedance Spectroscopy (BIS). Time Domain Reflectometry, Joint Time-Frequency Domain Reflectometry is carried out. Although some of these test methods have been able to detect local degradation but to interpret the type of defect is still infancy. This work uses the BIS method with RG 58 CU cable of 33.5 meters total length. The degraded portion is done by using several types, the first is to use mechanical damage by bending beyond the cable’s tolerance limit damage, and the second is by connecting the resistance (100 Ohm) or capacitance (10nF) value using the T joint connector. The results are comparing by simulation with ANSYS Electronics Desktop. The results are the type of defect caused by the mechanical press, and the peeled parts have different characteristics. Besides, the IT transform method and IFFT method both of them can detect precisely the degraded portion at 18.5 meters long of 33.5 meters total length of the cable under test.","PeriodicalId":314015,"journal":{"name":"2021 11th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131378555","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 Vietnam, socioeconomic condition, current traffic infrastructure and users’ habit are main causes of the prevalence of motorcycles, especially in large urbans. A huge number and high density of personal gasoline-powered vehicles has pressured traffic infrastructure and this is claimed to be the major contributor to air pollution. With reasonable purchase price and low operation cost, electric two-wheelers (e-bikes, electric mopeds, electric motorcycles) could be seen as a promising solution for replacing gasoline-powered motorcycles. In order to promote this transition, supporting infrastructure such as charging facilities should be studied, investigated and deployed. Nevertheless, electrification of mobility is only beneficial to environment if the electricity used to charge EVs comes from renewable sources and not from fossil fuel generation. With high potential of solar energy, local consumption of PV generation for charging stations in Vietnam may provides a promising solution. This paper aims to research the trend of transport electrification and the feasibility of PV-integrated charging stations for electric two-wheelers in Vietnam as well as propose PV-based charging station solution at Electric Power University.","PeriodicalId":314015,"journal":{"name":"2021 11th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116201280","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 particular, we compare models that used different approaches for forecasting weekly average price and price density, and clarify the following empirical results using the data from Japan Electric Power Exchange (JEPX): 1) Instead of using forecasted temperature directly as an explanatory variable, the two-step forecast method with measured temperature is more likely to reduce the forecast error; 2) Quantile regression has better density forecast accuracy than a GARCH based model; 3) The multiplicative model using the logarithmic price series tends to have higher forecast accuracy than the additive model without logarithmic conversion; 4) Weather forecasts contribute to improving the forecast accuracy of weekly electricity prices and also play an important role in earning profits in forward market trading. The proposed arbitrage trading method can be utilized by many participants in that the strategy can be flexibly changed according to the level of risk tolerance. The existence of considerable arbitrage opportunities in the JEPX forward market, revealed by the empirical results, may have practical implications on attracting traders and stimulating the market.","PeriodicalId":314015,"journal":{"name":"2021 11th International Conference on Power, Energy and Electrical Engineering (CPEEE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114148080","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}
