Gubía","doi":"10.1109/MELCON.2014.6820517","DOIUrl":"https://doi.org/10.1109/MELCON.2014.6820517","url":null,"abstract":"Nowadays trains offer a level of comfort and services that obviously imply a higher energy consumption to feed the auxiliary train power systems. Usually, the auxiliary power systems are fed by two power converters placed in opposite ends of the train. These power converters share the demanded power and depending on how over-dimensioned the system is, they offer a certain level of redundancy. The correct functioning of the converters set in parallel may only happen if the right synchronization of the voltage generated by each of them is guaranteed. Otherwise, there would be an inadequate flux of power flowing between them. There is an increasing interest on operating the converters set in parallel without the need of a communication line to transmit the signals to synchronize the converters so as to simplify the system and make it more robust. The Droop Control technique, based on the steady-state regime power flux analysis, enables such goal. This article analyzes the decisive impact of the supply line on the dynamics and the stability of the system based on the Droop Control technique. Furthermore, a simplified model that integrates the control loops of both converters and the line dynamics is proposed. This model accurately analyzes the train auxiliary system power flux behavior both during steady-state and transient regimes. Hence, the suggested model is an adequate tool to study control strategies.","PeriodicalId":103316,"journal":{"name":"MELECON 2014 - 2014 17th IEEE Mediterranean Electrotechnical Conference","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128437726","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 resulting aggregated load pattern indicates the system response that may be more or less flexible in different periods of time. Many research activities have been dedicated to explore the flexibility of load demand using load patterns and associated uncertainties but little work is found on investigating the effect of sampling time and aggregation level on the shape of the load patterns. Knowing the characteristics of the electrical load patterns is a key aspect to manage load and supply side flexibilities for most economic system operation. This paper addresses the effects of sampling interval as well as aggregation level on the characteristics of the aggregated load patterns. The study is carried out on the basis of comprehensive statistical computations on collected data using load variation profiles, because these profiles embed the information on the load variation trend. The findings of this study may be used for load forecasting and management, generation allocation and economic operation of smart grid system, especially for microgrids.","PeriodicalId":103316,"journal":{"name":"MELECON 2014 - 2014 17th IEEE Mediterranean Electrotechnical Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129930117","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}

Once the satellite is launched then this resolution cannot be changed during the lifetime of the satellite. The only way to increase the resolution of the images is by using super-resolution techniques. This paper deals with the design and analysis of 2D filters for improving the resolution of interpolated satellite images. The images are reduced first by a certain factor and then interpolated back to the original size. Linear phase 2D filters are designed to optimize the mean squared error (MSE) between the interpolated and the original satellite image. Then the satellite image is enlarged by the same factor and the 2D filter is used to sharpen the image. The performance of the new sub-optimum filters was assessed by using the peak signal to noise ratio (PSNR) and the structure similarity index measure (SSIM) on a variety of satellite images. It has been found that this method yields better results than using standard sharpening filters and very close to the optimum case when the resolution of the enlarged image is known.","PeriodicalId":103316,"journal":{"name":"MELECON 2014 - 2014 17th IEEE Mediterranean Electrotechnical Conference","volume":"80 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114043641","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}
