The numerical method is based on Reynolds averaged Navier-Stokes (RANS) approach opting the realizable $mathrm{k}-varepsilon$ turbulence model for turbulence, the non-premixed combustion model for gas combustion, the Lagrangian method (DPM) for the discrete second and the PI for radiation.

In this context, our work is oriented towards the implementation of a photovoltaic pumping system (PPS). Power maximization is done with a most classical Perturb and Observe (P&O) method). The PPS is implemented using dSPACE DS1104 board. The motor used is a single-phase induction motor (SPIM), which has the advantage of simplicity in control and in operation, it’s low cost compared to the three-phase motor. Through this work, we are looking to design an experimental platform with simple electronic systems and a low cost prototype used in both research and industry for the measurement of the photovoltaic electrical characteristics with rapid tracking of the maximum power and application to water pumping. The results obtained through simulation and practices are given and show the effectiveness of the suggested system by using different levels of solar irradiation. The proposed PV pumping system is installed in the research laboratory LTII of Bejaia University (Algeria). This system is simple and inexpensive for a small-scale pumping system.","PeriodicalId":186042,"journal":{"name":"2018 6th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126060165","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 process of charging is possible without using the method of state of charge estimation of the lead acid batteries that can produce a dangerous charging process if the batteries state of charge did not estimated with a good precision.

These onboard electronics include a wide variety of controls and sensors for maintaining wind turbines within their operational ranges. As such, interference or interruptions of these electronics can cause unwanted system behavior or worse, system damage and destruction. A significant source for wind turbine performance degradation or reductions in reliability comes in the form of static electricity. As wind turbine blades sweep through the air, electrostatic accumulation occurs on the wind turbine blade surfaces. This accumulation can have detrimental effects on the system’s equipment unless proper precautions are taken to mitigate static electric charge accumulation. The scope of this research is to analyze the capability and effects of electrostatic accumulation on wind turbine components. This research is intended to (1) define the current risk that static electricity poses to wind turbines, (2) investigate causes for static electric accumulation, and (3) assess potential mitigation methods to better safeguard wind turbines against the effects of static electricity.","PeriodicalId":186042,"journal":{"name":"2018 6th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130509651","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}

Machine learning models are the most accurate models used in prediction. The goal of our study is to predict the electricity power consumption every 10 minutes, and/or every hour with the determining objective of which approach is the most successful. To this end, we will compare different types of machine learning models that recently have gained popularity: feedforward neural network with backpropagation algorithm, random forest, decision tree, and support vector machine for regression (SVR) with radial basis function kernel. The parameters associated with the comparative models are optimized based on Grid-search method in order to find the accurate performance. The dataset that is used in this comparative study is related to three different power distribution networks of Tetouan city which is located in north Morocco. The historical data used has been taken from Supervisory Control and Data Acquisition system (SCADA) every 10 minutes for the period between 2017-01-01 and 2017- 12-31. The results indicate that random forest model achieved smaller prediction errors compared to their counterparts.","PeriodicalId":186042,"journal":{"name":"2018 6th International Renewable and Sustainable Energy Conference (IRSEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129120063","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 paper studies the structural analysis by the finite element method of the gearbox of the wind turbine with an epicyclical gear system, under different excitation conditions. This analysis was according to the variation of operating mode or the type of epicyclical gear train. It gives us a vision of the concentrations of stress, in order to minimize the propagation of cracks and to estimate the lifecycle of the system. This investigation will play a very important role in the correct functioning of the power transmission system. In addition, it gives us an idea about the wind turbine gearbox vibration, so the compound that causes more noise.

In this study, some conventional generators are replaced with renewable sources as wind and photovoltaic (PV) power for IEEE 30-bus standard test system. The randomness of power generated by wind and PV is modeled. The problem is solved based on expected values of generated renewable power using the Probability Density Function (PDF) and the Cumulative Density Function (CDF). Weibull and lognormal probability density function are used to calculate available wind and solar power, respectively. Two cases (with and without renewable sources) were considered in the evaluation.
