The sliding mode controller (SMC) is designed for a class of non linear dynamic systems to tackle the problems with model uncertainties, parameter fluctuations and external disturbances. In SMC, the high frequency chattering phenomenon results from the discontinuous term in traditional sliding mode control is highly undesirable. In this paper we use the fuzzy logic to reduce the chattering phenomena. The system stability analysis is carried out using Lyapunov stability theorem. An asymptotically stable observer is designed to overcome the problem of speed sensor and is obtained without affecting the overall system response. The simulation results show the effectiveness of the proposed control strategy with desired tracking accuracy and robustness.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129913183","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 approach is most suitable for cells made of materials that have the same lattice constant, because this results in less defects, and hence, a high efficiency. If the cells do not have the same lattice constant, then more complex and costly growth techniques are used. Alternatively, the non-lattice matched cells can be kept apart (i.e. not stacked) and integrated in an optical system that splits the sunbeam into several sub-beams and direct each towards one cell. In this study, we are demonstrating this last approach consisting of an optical system with beam-splitting features, encompassing two solar cells: AlGaAs and Ge.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114198591","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 whole integrated or interconnected system has been used to supply an AC load with certain power that is desired to be kept constant without regard to the surrounding insolation or irradiation levels. A maximum power point tracker has been used in conjunction with the PVG module and that is to guaranty the maximum exploitation of the the PVG power and to ease the burden on the fuel cell (FCG) power.

However, most of these sources are located far from the load centers, and the existing power system is getting overloaded. A supergrid is by many seen as a viable solution that allows a massive integration of these renewable energy sources into the European power system. By connecting energy sources that are located far from each other and by offering enhanced control, balancing services can be delivered. The geographic spread in its turn allows a more diversified energy portfolio. In the meanwhile it increases the security of supply. Although the supergrid has gotten much attention, it cannot be built yet. While the basic technology might seem available, several technical limitations still exist. This paper first describes the potential and need for a supergrid. The paper focuses on a meshed, multi-terminal VSC HVDC, and it is explained why this relatively new technology is believed to be the best suitable one for such a grid. Next the different difficulties or challenges that still exist are addressed.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134557087","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 vehicle applications fuel cells operate under load change conditions. Sudden load changes may result in improper water management and reactant starvation phenomena due to the slow response of the cell to load change, which results in performance loss and short lifetime. So understanding the dynamic behavior of PEM fuel cell is essential to achieve longer fuel cell lifetime and better performance. In this article a transient along the channel model has been developed to investigate temperature variation in anode, cathode gaseous stream and fuel cell stack. This lumped model is also capable of predicting the time history response in anode, cathode and stack temperature as well as water vapor and reactant partial pressure in flow channels and output cell voltage when a sudden change in the current load demand occurs. Results from this model show that solid temperature is mainly affected by the generated heat due to the electrochemical reaction. It is found that during load change, an appropriate water management can sustain maximum conductance in the membrane so that voltage drop in the cell due to the membrane resistance is minimized.","PeriodicalId":386008,"journal":{"name":"2010 IEEE International Energy Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121819690","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}
