The harmonic distortion that the charge controller produce it on the grid for eight scenarios at different hours for winter and summer semesters was analyzed, also the effect of V2G technology on the stability was found for fourteen scenarios at different penetration level for electric vehicles, at the end the effect of V2G technology on voltage stability was found for three cases. The results compared with IEEE standard for the allowable harmonic distortion limits where the highest total harmonic distortion occurs at summer peak and high penetration for electric vehicles which equal 0.37%, the frequency stability results compared by the NECA (National Electricity Code Agency).","PeriodicalId":378157,"journal":{"name":"2017 8th International Renewable Energy Congress (IREC)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122713992","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}

These losses appear in the form of mismatch power losses. Minimizing these losses is fortunately possible through reconfiguring the connections of PV modules in a PV system, as reported recently in the literature. However, the available reconfiguration methods are based on biological optimization which needs long computational time to search for the optimal configuration. Unfortunately, this hinders their practical implementation in large PV systems. A reconfiguration technique that finds the optimal configuration in a reduced computational time is proposed in this paper. Simple rules are developed that can determine the best PV configuration without the need to solve heavy optimization problems. The validity and superiority of the proposed method is verified by comparing its performance to the existing methods under various shading scenarios.","PeriodicalId":378157,"journal":{"name":"2017 8th International Renewable Energy Congress (IREC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131362834","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}

This work deals with the analysis of both the technical and economic feasibility, and then the environmental and social impacts of a 95 kWe gasification plant project in order to generate electricity for Badara village in Burkina. Two biomasses feedstock: cotton stalk and rice husk are used. Mass and energy balances of the processes were performed to assess technical performance. Levelized cost of electricity (LCOE) analysis is used to estimate the production cost of the two biomasses options. The environmental impacts were assessed by using a Life Cycle Assessment (LCA) approach. The results show that the valorisation of the rice husk is the solution that offers the low production cost (0.34 €/kWh) compared to cotton stalk (0.38 €/kWh) despite its low electricity efficiency (11.9% against 12.6%). Nevertheless, the use of the cotton stalks is most interesting in terms of direct job creation (9.58 full-time equivalent jobs /year against 8 full-time equivalent jobs /year). Concerning the environmental issue, the gasification of cotton stalk generates consistently higher environmental burdens than the rice husks gasification. This assessment represents an important step that could assist the policy maker to make a relevant decision for this local conditions and available resources.","PeriodicalId":378157,"journal":{"name":"2017 8th International Renewable Energy Congress (IREC)","volume":"342 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134114515","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, limited knowledge and information is available regarding PV performance over a long period of time under the influence of local geographical climate considerations. Therefore, PV degradation data could be vital for the stakeholders to ensure safe and long term operation of PV modules. To accomplish, it is necessary to address the PV electrical parameters degradation locally. The analysis showed that the average degradation of commercially available three silicon crystalline modules in six different sites is around 1.55%/year and median degradation is observed to be 1.28%/year. Further, analysis showed that losses of short-circuit current (Isc) were responsible and higher for the maximum power degradation (Pmax) in hot and dry climate than hot and humid climate conditions.","PeriodicalId":378157,"journal":{"name":"2017 8th International Renewable Energy Congress (IREC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129702650","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 addition, with the limited fossil energy resources, the need for sustainable and environmentally friendly energy sources is increased. Energy hubs as one type of DG, have made the local use of multi energy carrier systems economically attractive. In this paper, a modified firefly based algorithm is proposed to optimally dispatch the energy hub input energy carriers. The objective is to minimize the total energy cost and emission amount of the energy hub while maximizing the cost of electrical and heating energy sold back to the network. The proposed algorithm is applied to a commercial facility (hospital) as a case study. The results show the effectiveness of the proposed algorithm in solving the optimal dispatch of the energy hub components while reducing the overall cost and satisfying the system operational constraints.","PeriodicalId":378157,"journal":{"name":"2017 8th International Renewable Energy Congress (IREC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131651330","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}
