There has been more focus to installation of Renewable Energy Sources (RES). In Japan, PV system introduction is promoted by national policy of the government in 2012. However, the large amount of distributed generator causes voltage deviation beyond the statutory range in distribution system. Furthermore, supply-demand balance becomes difficult because the generated power is influenced by the weather condition. The current transformer cannot solve the voltage deviation problem which is caused by renewable energy, due to relatively slow behavior. This paper considers using interfaced inverters which are used for distributed generators. This voltage control method can be achieved without introduction of additional reactive power control devices. Recently, isolated operation has been attracted attention. This paper also presents isolated operation method in distribution system. The effectiveness of the proposed distribution system is verified by computer simulations on Matlab/SimPower systems® environment.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124835186","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, one major problem with solar panel systems is that the efficiencies for such systems are still poor and the costs per kilo-watt-hour (kWh) are not competitive, in most cases, to compete with petroleum energy sources. Using solar cells to get electrical energy is a complicated method. This is due to many factors that affect the performance of solar systems including the material that is used to manufacture solar cells themselves, the orientations of a group of cells (panel), and the angle of sun incidence.The aim of this research is to choose the efficient tracking method for real solar tracking system in the northern area of Jordan to get the maximum gained power based on real time data. The proposed tracking system was located at Jordan University of Science and Technology (JUST) campus in northern Jordan. Data were collected at different days of the year to find the maximum gained power. Three tracking techniques were evaluated, namely, Fixed-due-south, tracking_to_the sun, and no-side-shadow. Tracking using no-side-shadow method achieved the maximum gained power compared to both of tracking_to_the sun and fixed_due_south methods, it's also better and efficient than both of techniques by 13.8% and 29.1% respectively.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125895303","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}
