For an optimal GPV power extraction, one of emerging PS mitigation techniques is to reconfigure the PVG by altering the electrical connections between panels according to prevailing conditions. This paper presents a reconfigurable PV architecture based on irradiance equalization row approach for a PVG connected on Total cross tied (TCT) scheme. The proposed technique uses fuzzy logic as an optimization tool to obtain uniform shade dispersion throughout the PVG, either keeping the same number of panels in each row or forming rows with different number of PV panels. To evaluate the effectiveness of proposed fuzzy logic controller (FLC), extensive simulations with different shade patterns are carried out on Matlab/Simulink. Thorough analysis with the help of characteristics curves and the results obtained for the full PV chain conversion are performed. Results of simulation show that the proposed reconfiguration method exhibit superior results as compared to fixed TCT interconnection and enhanced irradiance equalization (IEq) method in terms of efficiency, power loss and response time.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"91 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80783759","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}

For this purpose, 11 years of measurements hourly data in terms of wind speed and wind direction recorded at 10m a.g.l. were used. For the temporal analysis, the Weibull distribution were used to study the monthly, annual and diurnal wind potential, while the WAsP program were used to establish the wind map and to find the windiest area for wind farm energy production simulation at this desert region. Given that the major part of southern regions in Algeria have an isolated grid, powered by gas and diesel turbines, this study proposes an environmental analysis which assess the quantity of C02 not emitted into the atmosphere during a life cycle of a wind power plant of 10 MW rated capacity, composed by 5 wind turbines of 2 MW from Vestas manufacturer, installed in this region. The analysis results for the meteorological station at a height of 10m indicate that the studied site has an appreciable wind potential with a mean wind speed equal to 5.76m/s and a mean power density of 196 W/m2, with the east as dominant direction. Regarding the temporal analysis, it is shown that the monthly mean wind speed ranges from a minimum of 5.1m/s in December to a maximum value of 6.1m/s in May. In addition, it was given that diurnal wind speed analysis gives a good potential in the daytime, while the wind potential is relatively calm during the night. Furthermore, the wind map given at 67 m, shows a mean wind speed which varies from 4 to 11 m/s over the whole studied region. Finally, the wind power plant energy production simulated at a windy site in the region of Illizi gives an annual energy production equal to 40.120 GWh, which leads to avoid the emission of 1754.47 Ton of CO2 equivalent.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"158 1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77809489","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 Photovoltaic (PV) and wind turbines are considered as resources of Distributed Generation (DG). The integration of PV - DG units into distribution systems has a significant effect on reducing the system active power losses. In this paper, a new technique based on the Moth Flame Optimization (MFO) algorithm, is used to optimally allocate the PV -DG units in Radial Distribution Systems (RDSs) and determine the optimal size of each unit. The objective of the technique is to minimize the total active power losses of the system, while satisfying several operating constraints. The proposed optimization algorithm is tested using three different IEEE standard RDSs of various sizes, which are 33, 69 and 118-bus systems. In order to demonstrate the applicability and the performance of the MFO algorithm, numerical simulations are obtained when applying the MFO algorithm, and compared with different existing optimization techniques. This comparison shows the validity of the proposed MFO algorithm.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"76 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82357141","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}

Many new plants are contracted constantly. Strategic planning and many other technical decisions are significant to these strategic systems. The proposed Artificial Intelligent (AI) methods provide decision makers with different choices for investment, where each is comprised of different desalination combinations regarding to locations, capacities, and energy sources in terms of several performance metrics. The intelligent decisions determine the optimal stations location and the water desalination system capacity for future expectations. Other smart decisions select the optimal desalination technologies for available existing and suggested desalination planting. In addition, AI methods provide decision makers to configure the pipeline network and transport water among the planting locations. The proposed work is a method to upkeep strategic decision making for the best water desalination facility. Our methodology offers a set of AI alternatives for several desalination plans. Decision support systems and tools are imperfect to deliver a set of alternatives. Therefore, the proposed work provides a systematic decision process to validate several water desalination alternatives, considering intelligent water pumping to the locations through the pumping network and water storage at every location. The proposed approach is validated for a case study in Jordan, which is a beginner country in desalination. The results show where economic and environmental benefits occurs. It shows how the AI methods can introduce an optimal settings of the desalination process to the peopole who makes decisions.","PeriodicalId":6671,"journal":{"name":"2019 7th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"83 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82730861","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}

Biogas could be a good renewable and clean substitute for other forms of energy in rural Botswana, however, the technical and socio-economic potential remains largely unexploited. In this study, the cattle dung was characterized, followed by a lab-scale experiments on the biogas potential yields from the dung. The bio-digester design was selected using the multi criteria decision analysis. From the six digester models that were evaluated for selection, the KVIC was found to be the most suitable with its size ranging from 10 to 100 m3, The bio-digester was subsequently designed using data and mathematical models obtained from literature. The biogas plant was designed for Lemcke's cattle farm, the best selected site, with 5000 herds. The feedstock was found to have an in-situ density of 1410 kg/m3 with a total solids (TS) content of 18.9%, volatile solids (TS) content of 80%.
