As a result, the need for high quality, low harmonic distortion, current injection into the grid is essential. To achieve this, careful consideration of the inverter controller is necessary. Many control methods are based on the traditional proportional-integral controller (PI), or the more recently adopted Proportional Resonant controller (PR). This paper presents a new technique of minimizing the error of the current control in a three phase grid connected inverter using a readily implementable Adaptive Proportional Resonance controller. Simulation and experimental results demonstrate the effectiveness of the proposed technique.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"42 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":"114933813","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}

Different models for solar cells are available in the literature. Dye-sensitized solar cells (DSSCs) are considered as third photovoltaic generation and are proposed as alternative to conventional silicon solar cells. They have numerous advantages over silicon based solar cells such as low materials cost and simplicity of production methods. In this work we present studies on the DSSC fabricated by electrophoresis deposition techniques (EPD) and sensitized by several natural dyes. Comparative study between two Pspice electrical models using four and five parameters has been investigated using experimental results deduced from I-V curve. The obtained parameters are used as Pspice input data to simulate the I-V curve for the two models. The results show that the four parameters model is in agreement with the experimental results.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"193 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":"116102100","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, endowing the process with more sophisticated instrumentation will not only increase the investment capital in the plant, but also the maintenance planning and scheduling time. Furthermore, some process variables that are of relevance cannot be measured. A cost-effective way to overcome such limitations is by using the soft-sensing methodology. In this work, a virtual sensor is developed for a biomass heat recovery power plant to predict multifarious key process variables that will help in estimating the calorific value of biomass solid fuel. For this purpose, the process measurements, obtained from the existing physical instrumentation, are leveraged by using an analytic model, which is based on biomass combustion stoichiometry. Finally, the concept is validated by comparing the predicted steam amount obtained from the soft-sensor against the measured one.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"47 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":"122235127","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 the end of 2013, five different PV module technologies which are: m-Si, CIS, HIT, Back Contact and a-Si_μc-Si, and a weather station were installed at the city of Saida located at the gate of the great Algeria's Sahara desert. The objective of the present work is the study of the behavior of solar PV modules in outdoor conditions and to compare their performance parameters in order to find which technologies are suitable for the Saharan climate conditions. The modules were characterised by measuring their I-V curve in outdoor at the location without shadow. Moreover measurements of various parameters such as irradiance, temperature and humidity, using the weather station were performed. Finally performance parameters as performance ratio, energy yield and temperature losses are given and analysed.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"61 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":"129315309","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}

There was a considerable decrease in weight loss in the region of 280°C to 380°C attributed mainly to the cellulose degradation. In a second step, the activated carbons were characterized different analytical techniques. In particular, the effect of carbonization and chemical activation on the cross-section and surface was detected with SEM. In addition, FTIR analysis showed the disappearance of many surface groups in range between 2000 cm-1 and 4000 cm-1 after activation while TPD-MS showed that with the acidic character of the activated carbon with H3PO4 comparing to ZnCL2.
