Advantages of MICs are explained through an example with a photovoltaic (PV) system. Feasible MIC topologies for renewable energy applications are discussed and classified into four different MIC families. According to their different configurations, each MIC family is suggested for certain renewable energy applications. Furthermore, possible operating issues of MICs, such as relatively low efficiency, are also discussed. Design considerations for extending MIC's voltage step-up ratio and achieving maximum power point tracking on all PV sources through are commented. Issues in modeling and control are also discussed, showing that it is important when evaluating closed-loop stability to consider nonlinear and time-varying characteristics of both renewable energy sources and the MIC. Design and synthesis of a multivariable controller that achieves quadratically stabilization and satisfies the H∞ and pole-placement constraints for MICs is reviewed, too.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129817412","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 Europe, the growing number of offshore wind farm projects calls for scrutinising merits and opportunities of their interconnection via multi-terminal links rather than conventional point-to-point connections. The semiconductor components used in the converters and the resistance of power cables are expected to introduce new power losses in the transmission system. In this study, star and ring configurations with four DC nodes of multi-terminal grid topologies for renewable energy integration are modelled by means of NEPLAN software. In order to address more interconnection options the authors examine several grid topologies having more than three interconnections. The simulation results of the different network configurations, the power losses level in particular, are compared and analysed. The simulations illustrate an increasing complexity of network operation and power balancing, from a low power up to the rated power capacity injected at the inverters terminals.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129937293","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}

Additionally, the major parts of the used electronics devises in the buildings operate with the DC current, such as computers, air conditioning, and multimedia. Based on these remarks, the authors propose an energy management method for the decentralized energy generation systems. The studied system includes the renewable energy sources (wind energy, and photovoltaic panels), the energy storage devices (lithium-battery, and Ultracapacitors), a programmable DC-Source for the Diesel generator behavior emulation, and the electronics load which emulate the electrical energy consumption in the building. Contrary to the previously works, the proposed control method is focused on the residential micro-grid energy management according to the dynamic responses of the sources and their availability. The performances of the method are evaluated through some simulations and the experimental tests, dedicated to residential micro-grid applications.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128886337","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 system here proposed can be useful for electric vehicle (EV) battery charging systems. It consists mainly of two copper wire coils, placed one in front of the other on the same axis. The inductor coil can easily be placed under the road surface (in a parking), while the other (the receiver coil) in the lower side of the vehicle. By exploiting the coils resonance coupling effect, electric energy can be transferred from the inductor coil to the receiver in order to charge the batteries. Low cost experimental tests carried out at DIEETCAM - University of Palermo, demonstrated the effectiveness of the proposed wireless power transfer prototype, being it capable to reach an efficiency of about 80% and more along a distance of 30 cm.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121340076","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}

Generally, the photolithography technology employed in semiconductor manufacturing is used to manufacture microchannel chip dies.
