This paper studies the quality of electric energy in microgrid of tens of kilowatts. Indeed, the integration of a fast element of storage with supercapacitor in a microgrid constituted by a wind turbine and photovoltaic generator reduced significantly the fluctuations of power at the terminals of electric charge. Different tests under different climactic conditions showed the ability of supercapacitor to absorb the rapid fluctuations caused either by the renewable energy sources or by the load itself.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"139 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121001452","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 robustness is guaranteed by the use of the Internal Model Controller (IMC). The IMC is based on the artificial Neural Network (ANN) principle. This paper proposes an adaptive neural controller methodology in the dc motor control and the results are compared with the performance of the feedforward neural controller. Simulations results and experimental set up are presented to demonstrate the robustness of the speed controller under a wide range of load of the proposed schemes in a closed loop control. The effective results show that the performance of neural network control dc motor is improved by using adaptive neural network than the feed-forward neural network.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126087183","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}

Control strategies for such train systems must be taken into account when the swell excitation forces exceed the rated value corresponding to the rated power of generator and converter. Over-rated swell effects occurs at large spring tides or under strong sea states; in these cases maximum power leveling strategies must be adopted to limit the generator power at rated value. In this work, power limitation strategy with flux-weakening control is investigated. This later is applied to extend the rotor speed operating range over the nominal speed during high speed swell effects. Robustness and performance of the considered system with flux weakening control of the PMSG are evaluated. Simulations are carried-out to highlight the proposed PMSG-based DWEC performance under flux weakening conditions.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124637422","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 describes the direct torque control of voltage source inverter fed interior permanent magnet Brushless AC motor drives, considering a fuzzy logic-based speed controller which offers robustness against reference speed and/or load torque disturbance effects. In this research study, according to speed error and its first time derivative, the proportional and integral gains of the speed controller are online adjusted. A simulation-based comparative study between the performance of the proposed speed controller and the conventional one, has highlighted the superiority of the developed controller which exhibits fast dynamic response, more robustness and less steady-state error especially when there exist motor parameter uncertainties and unexpected load changes occur.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127507335","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 aim of this work is to keep the PEMFC working at its maximum operating power point in presence of inputs and load variations. However, due to the low output voltage of the PEMFC, DC/DC boost converter is used to obtain regulated high voltage DC. Therefore, the SMC is proposed to fix the fuel cell current by driving the boost converter connected between the fuel cell and the load. Stability of the closed loop system is analytically proved. The proposed SMC is validated by simulation studies in MATLAB/Simulink and results are discussed. Fast dynamic system response and robustness against load and input voltage variations are obtained.","PeriodicalId":214657,"journal":{"name":"2017 International Conference on Green Energy Conversion Systems (GECS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116859550","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}
