Starting from the basic schematic of an off-grid PV system, the first step is dedicated to the identification of each stage main external electrical characteristics, in order to build up a homogenous conversion chain, responding to the fixed objective. This is done without ignoring many of the practical sizing constraints to make the final design as near as possible to its detailed field realizable configuration. A progressive modelling process is then initiated with the chosen structure of the PV array (PVG). As a result, the external characteristics of the latter are established in presence of the main field perturbations such as solar irradiance intensity, temperature and shading variations. A maximum power point tracking stage (MPPT), based on the “perturb & observe” (P&O) approach as a control strategy of a boost DC-DC converter is then introduced, implemented and optimised. Its behaviour is investigated under a multitude of the various working conditions quoted above, along with the load constraints. At this level, these are related to the battery pack mainly arranged to fulfil DC bus voltage considerations. Significant results in this scope are presented, before introducing a three-phase Voltage Source Inverter (VSI), which direct control circuits are based on the analog PWM technique. An output voltage regulation loop is then designed to assure optimum static and dynamic performances in presence of the main user AC load perturbation profiles. At the end, significant and realistic operating conditions are introduced to evaluate the overall performances of the completed installation, before conducting some representative validating tests which related results are presented and discussed.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116596929","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 aim of this project is to improve energy efficiency order to minimize the electricity cost consumed at the laboratory, because according to the bills of electricity received we noticed that there is a high consumption of electrical current, from the STEG grid, and especially by the energy intensive equipment such as drying ovens and all the workstations. So we targeted to install a photovoltaic field of 12KWc to reduce these bills by using other sustainable, green and clean sources. In addition, a theoretical study of the PV system sizing realized manually in order to know in the first hand the compatibility between the different equipment of this installation and to compare the results with those found by the SMA Sunny Design software in the second hand. Then, we present the different result obtained by the simulation of our installation using a PV*SOL simulation software. We designed and managed these systems optimally to promote the self-consumption of the electric energy in the building of LPT Research laboratory. We will focus on the use of the PV system by evaluating the impacts of electricity generation using renewable energy levied on electricity grid (energy injection and extraction) and the economies that can be achieved during the hours Operating.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130255702","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 effects of the intensity of the chemical treatment with NaOH, the sawdust dose, contact time and the initial MB concentration were examined in batch system. Analysis of variance (ANOVA), F-test and Student's t-test revealed that the chemical treatment concentration is the most influencing parameter, followed by the contact time, treatment dose and the initial dye concentration. An optimum treatment/adsorption point was determined for a 100% MB removal yield using MINITAB's desirability function for the recommended optimum conditions of: NaOH concentration of 0.14 M, an adsorbent dosage of 50 g/L, a contact time of 1 hour and a MB concentration of 69.5 mg/L. The physical-chemical characterization of the generated sawdust through FTIR, SEM, EDX and BET analyses showed a non negligible shift in the hydroxyl and aromatic functional groups and an important variation of the surface morphology and texture. The Kinetic and isotherm MB adsorption experiments carried out on the chemically modified sawdust demonstrated that the pseudo-second order and Langmuir models fitted very well the kinetic and at equilibrium experimental data, respectively. These findings confirm that the MB adsorption is mainly governed by a chemisorption phenomenon and was driven with a monolayer fixation process. The MB adsorption capacity of the modified sawdust was relatively important and indicates that this solid matrix could be considered as a promising material for dyes removal from industrial effluents.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126378033","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}
