The electricity sector suffers from frequent power blackout of 3 to 16 hours per day in all cities in the country. More than 39% of electricity is generated from private diesel generators. Lebanon's geographic location makes it benefit from mild climate and 1900 kWh/m2 as solar radiation yearly average which forms a sustainable energy source that will reduce energy outages. Hybrid photovoltaic (PV)-diesel system combines photovoltaic technology and diesel generators to profitably use abundant and free solar energy as source in industrial or applications that need cooling in summer. This paper presents an application of hybrid PV-diesel system in a tertiary building in Beirut that needs cooling in summer. A detailed feasibility study of hybrid PV-diesel system is performed. Results show that the PV-diesel system can ensure 260 kW of electricity among the year. The system is cost-effective in the economic conditions of the country and can be used as base for large scale future projects in the same field where area for PV panels is available.","PeriodicalId":158844,"journal":{"name":"2016 3rd International Conference on Renewable Energies for Developing Countries (REDEC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127536377","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 order to extend the life time and runtime of batteries, an equalization process, with a good precision is required. Indeed, as mentioned in prior works, to achieve voltage equalization, the process must have a precision around 10 mV/cell. We have focused the impact of an unbalanced cells voltage on their lifetime. Typically, there are two equalization systems: While the active cell equalization processes remove charge from higher energy cell(s) and deliver it to lower energy cell(s), the passive methods, based on resistor element, remove the excess charge until the charge matches those of the lower cells in the same pack. It shows that the performance of active systems is significantly better than passive systems. Experimental results show that even for maintenance free batteries, a periodic equalization process is needed in order to extend their lifespan.","PeriodicalId":158844,"journal":{"name":"2016 3rd International Conference on Renewable Energies for Developing Countries (REDEC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115831683","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}
