This paper will illustrate the design and the performances of a shrouded hydro turbine to harness clean energy from marine and river currents. This system has been developed and tested at the University of Naples, to explore the feasibility of plants based on such idea. Two different diffusers have been designed, realized and tested. A simple designed method has been carried out in order to define the diffuser pitch angle. In order to evaluate the design diffuser angle in more accurate way a numerical simulation has been carried out. The experimental test results were compared with the bare wind turbine. The data were non-dimensionalized with respect to the disc turbine area in order to compare the ducted turbine performances with a bare turbine with the same overall size of the ducted wind turbine.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117074378","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 identification of design criteria for the optimization of the power stage of a DMPPT converter is a challenging task because the expected goal is to figure out a DC-DC converter able to achieve a trade-off between technical and economic aspects. In this paper the guidelines for a high efficiency and reliable DMPPT boost converter design are presented also considering energetic and thermal aspects. European efficiency and Californian Energy Commission weighted efficiency are calculated. Finally an “optimum” solution reliability performances are evaluated.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115104129","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 first result is that p type bulk silicon, as it was used in conventional solar cells technology, gives best results than n type only for the Jsc parameter. For concentration factors in the range X = 10 to 20, higher efficiencies (η = 16%) are obtained with the two type of solar cells.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123148877","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}

However, many hydropower plants have been in service for decades and are built with obsolete technology. In order to better exploit their potentialities, they often need large renewal or revamping actions. This paper offers an example showing how a traditional 600-kW run-of-river hydropower plant performance and layout can be enhanced by replacing fixed-speed induction generators with variable-speed permanent-magnet generators suitable for direct coupling with the hydraulic turbine and connected to the grid through an AC/AC power converter.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123631557","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}

For high power applications, 4-phase parallel boost converters are implemented with a switching interleaving technique for a fuel cell (FC) converter, and 4-phase parallel bidirectional converters are implemented with a switching interleaving technique for a supercapacitor converter in the laboratory. As controls, mathematical models (reduced-order models) of the FC converter and the supercapacitor converter are given. The prototype small-scale power plant studied is composed of a PEMFC system (the Nexa Ballard FC power generator: 1.2 kW, 46 A) and a supercapacitor module (100 F, 32 V, based on Maxwell Technologies Company). Simulation (by Matlab/Simulink) and experimental results demonstrate that the nonlinear differential flatness-based control provides improved dc bus stabilization relative to a classical linear PI control method.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129652498","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}

Efficient forecast tools are necessary to predict the energy demand of the supply area of the cogeneration plant. The tools are needed to control and optimize the operating schedule of the different units of the cogeneration system. The paper describes the data management and the mathematical modeling of the power and heat demand by neural networks. The design of clusters depending on seasonal impacts and the influence of climate factors are investigated. The paper shows that neural networks with similar structure can be applied for both the power and the heat demand forecast.

Any effort to decrease capital and operating costs, contributes to increase penetration of hybrid systems in power generation systems. In this paper combining of hybrid systems and Thermal Energy Storage (TES) has been proposed for lowering the costs of hybrid systems in hot climate. Since nowadays TES is known as an economical option in various sectors, therefore TES is selected for combining with hybrid systems. Optimization results show that, using TES in hybrid systems leads to significant reduction of the battery bank size or consumed fuel by backup systems like diesel generator. Therefore in hot climate, the hybrid systems which equipped with TES will be more economical than the conventional ones.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126729056","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}
