The system consists of a PV array, DC-DC converter and a DC-AC inverter coupled to the grid network. Our goal is the achievement of three control objectives i) regulating the DC voltage to a desired value (Vdc*) ii) supply a current with sinusoidal form and in phase with the grid voltage by controlling DC/AC converter (Unite Power Factor: UPF) iii) extracting the maximum power from the PV array by acting on the DC/DC converter (MPPT). The control strategy is based on the robust integral Backstepping control design to be applied to the DC_DC converter and the DC_AC inverter in order to optimize the PV energy extraction and to achieve unity power factor. In order to improve the robustness of the nonlinear control, an integral action is introduced. The stability of the nonlinear control is demonstrated by means of Lyapunov analysis. Representative computer simulations demonstrate the performances of the control strategy to track the maximum power point of the photovoltaic array panel and synchronization of grid current with grid voltage under various climatic conditions.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"11 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":"125730284","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}

A compromise solution must be made between energy supply quality and the selected optimization criteria. This paper proposes a methodology to study the load profile impact on SAPV system reliability and storage component. The main objective is to introduce some changes on the load profile shape such as load shifting and amplitude modulation. The system operation was simulated for two days with different load profiles to raise consumers demand impact on battery bank State Of Charge (SOC), load satisfaction and the excess energy. The term used to evaluate system reliability is Loss of Power Supply Probability (LPSP), which is related to load satisfaction. Simulation results showed the efficiency of introducing some changes on the load profile. It enabled an optimal exploitation of the produced PV energy and insured a better supply to the load with minimum energy loss.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"18 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":"122026120","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 stator of the DFIG is directly connected to the grid while its rotor is connected to it via a cascade (Rectifier, Inverter and Filter). Thus, the current control and the continuous bus of the wind turbine is carried out by the adjustment of the DFIG rotor sizes based on the maximum power point tracking (MPPT) technique. The results of simulation obtained under the MATLAB/SIMULINK environment present the performance of the sliding mode controller due to its robustness face to the wind speed variation of thus its simplicity of implementation and the robustness even in the presence of internal and external disturbances. By conclusion, it enabled us to justify the reliability of the suggested model and the elaborated command.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"1 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":"129839608","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 technique is generally employed to determine the kinetic and stoechiometric parameters of biological processes, such as: the oxygen transfer coefficient K<sub>L</sub>a, the endogenous oxygen uptake rate OUR<sub>end</sub>, exogenous oxygen uptake rate OUR<sub>exo</sub>, the total oxygen uptake rate OUR<sub>t</sub>; the substrate affinity constant (K<sub>S</sub>), the maximum growth rate (μ<sub>max</sub>) and the yield (Y<sub>X/S</sub>). According to the literature, there is a large variability in the estimation of these kinetic and stoechiometric parameters, attributed to three key factors: the culture history, the parameter identifiability and the initial substrate to biomass ratio (S<sub>0</sub>/X<sub>0</sub>). KLa, depends on endogenous oxygen uptake rate OUR<sub>end</sub>, is a key constant in evaluating respirogramme-specific parameters. Generally, OUR<sub>end</sub> is assumed constant during dissolved oxygen variation. The effect of S<sub>0</sub>/X<sub>0</sub> ratio on kinetic and stoechiometric parameters has only been partially studied. The goal of this study was to assess respirometrically the effect of various S<sub>0</sub>/X<sub>0</sub> ratios (in the range of 0.01 to 0.23) on the kinetic and stoechiometric parameters of a heterotrophic activated sludge biomass (presence of ATU a nitrification inhibitor) and for both heterotrophic-autotrophic activated sludge biomass.","PeriodicalId":190533,"journal":{"name":"2016 7th International Renewable Energy Congress (IREC)","volume":"1 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":"131278338","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}
