Thanks to PV panels' cost drop and recent improvements in energy conversion systems, the PV installations are getting more and more integrated into power plants. Because of high correlation with weather conditions, accurate short-term PV output forecast is highly recommended. An accurate prediction is needed to assess the effective contribution of solar energy in the grid, and to overcome the problems of intermittence. This paper proposes a day-ahead prediction method of PV output, which estimates the power generated by solar panels with and without prior knowledge of solar irradiance. The proposed model is the random forest using bagging algorithm, characterized by built-in cross validation and immunity to irrelevant inputs. A special attention is paid to the choice of most influential weather conditions on future power. The proposed approach is validated through tests on real data from PV sites in Australia.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129695750","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}

Currently, the real problem is related to two essentials points, the charging time and the station of recharge availability. However, finding the best charger mode, that guarantee the efficiency and the minimum charging time is related to numerous exigencies. It is expected that the minimum of recharge time is related to the fixed station of recharge and this mode is efficient only in fixed cars. However, the real problem is related to the running cars, where it is unacceptable that at the middle of travel, the vehicle is stopped and we cannot found a real station of recharge. Therefore, we try to present all charging method and modes that guarantee all needs for users when car is stopped or running.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120991423","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}

However, a non proper DG allocation and sizing may lead to an increase in power losses and affect the distribution system stability. This paper presents a comparative study for DG placement methods based on four different indices which are voltage drop index (L-index), voltage stability margin index (VSMI), voltage performance index (VPI) and loss sensitivity factor index (LSF). The performances of these indices are evaluated regarding power losses reduction, voltage profile and voltage stability enhancement. Simulations are carried out on the 33-bus radial distribution system. The results have shown that LSF and L-index methods gives better performance compared to the others two DG placement indicators.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116739938","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 bubble pump, which is the driving element of the diffusion absorption machines, shows an example of the heated tubes. This article is devoted to the study of the behavior of flows in a bubble pump of a solar diffusion absorption refrigeration machine, uniformly heated along its section of length 1m and diameter 10mm, using the CFD (Computational Fluid Dynamic) software, Fluent package. This work has been realized supposing that the regime is laminar and the flow is monophasic. Numerical simulation permits to study the effect of heating flux on the temperature and flow velocity distribution. Where water, is used as a working fluid along the tube of the bubble pump. This work shows that the variation of the heating flux has no effect on the fluid velocity in the tube. However, it has an effect on the distribution of the fluid temperature along the section.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121326172","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}
