This situation leads to the need to dig trenches all across the field yet it is possible to use autonomous fields provided by photovoltaic panels and storage system, to avoid those long cables and trenches. The approach developed here is to analyze and compare the effective environmental impact of the autonomous heliostat field and a classical field by use of a Life Cycle Assessment (LCA) approach. In this paper, the components of each kind of fields are described and LCA is applied to both types of heliostat structures. Based on the obtained results, the energy supplied in the electrical grid heliostat is responsible for the higher environmental impact over its life-time even if the photovoltaic panel itself generates a huge amount of environmental impacts during production phase.","PeriodicalId":229457,"journal":{"name":"2012 First International Conference on Renewable Energies and Vehicular Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127249242","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}

Non-Dominated Sorting Genetic Algorithm (NSGA-II) is employed to search the optimal PSS parameters..

The system is a cold generating station driven by solar energy. The main elements of the cycle are a refrigerated space, an absorption refrigerator and a solar collector form. A simplified mathematical model, which combines fundamental and empirical correlations, and principles of classical thermodynamics and heat transfer, is developed. The proposed endoreversible model is then utilized to simulate numerically the system transient and steady state response under different operating and design conditions. In order to obtain a fixed temperature in the cold room in a minimal lapse of time, the determination of the command necessary heat flow is based on the energy balances. Compared to the collector efficiency, the collector temperature presents major influence on the conceptual and functional characteristics.","PeriodicalId":229457,"journal":{"name":"2012 First International Conference on Renewable Energies and Vehicular Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130630545","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}

Divers researches and efforts have been concentrated on the photovoltaic (PV) systems efficiency improvement and the accessibility to this technology. This paper presents an intelligent approach for the improvement and optimization of the PV system efficiency.

In order to perform this goal a special interest was focused on the neuro-fuzzy algorithm based on the Sugeno inference model. This paper presents a detailed study and design of a MPPT controller to insure a high PV system performance which can be selected for practical implementation issue.

The combination of several renewable sources (wind and photovoltaic) with a diesel generator is suited to electricity supply of remote areas. The purpose of a hybrid power system is to produce energy at all times requested by consumers and if possible to produce it from renewable sources, the stochastic nature of renewable energy makes fluctuation of real power on the network therefore on the frequency. This problem can be solved or avoided by satisfying the real power supply-demand balance constraint in the hybrid energy system. Using battery bank system can increase the penetration of renewable energy and absorb the rapid fluctuation due to the stochastic nature of renewable energy, that, it increases the difficulty of managing all these systems in real time, ensuring the quality of energy supplied. The objective of this work is to propose a methodology to design a fuzzy logic controller coupling with stateflow to improve its performances.","PeriodicalId":229457,"journal":{"name":"2012 First International Conference on Renewable Energies and Vehicular Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124327641","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}

Moreover, the method presented here can be used to evaluate the energy production in Sfax of photovoltaic projects like water pumping solar, on-grid applications and off-grid applications. The estimation method of the hourly and daily solar radiations used the Liu and Jordon model. In addition, the values of monthly of average daily solar radiation on a horizontal surface are taken from NASA, Surface meteorology and Solar Energy.

These equations are solved by a finite volume discretization method.
