Currently, in the Mediterranean area, access to services and energy by population, unevenly located in different countries, is largely unbalanced, with increasingly evident difficulties, which are expected to lead to the implementation of policies fostering a more balanced socio-economic development through the adoption of ICT technologies. We argue that by supplementing \"traditional\" approaches to business model identification with an investigation based on modelling techniques, supported by a benefits analysis, a more powerful business argument adoption can be developed. We also propose an outline framework supporting such an approach and assess the nature of the involved forces, to better drive the change currently impacting the growth of these technologies, and ensuring a more balanced development of the whole Mediterranean area.","PeriodicalId":368119,"journal":{"name":"2015 AEIT International Annual Conference (AEIT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128249523","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}

Thus, the use of batteries coupled with supercapacitors, that have a higher specific power and a longer lifetime, allow a better management of the battery in many grid-connected applications.

Due to the difficult authorization procedure for the construction of HV overhead lines, or even for the refurbishment of the existing ones, Battery Energy Storage Systems (BESS) can be an useful solution to local congestions. NaS batteries are the most mature and widespread solution for energy-intensive BESS, due to their relatively low cost and long lifecycle. However due to the high operating temperature, their efficiency decreases in case of low utilization. The present paper deals with NaS battery operation for congestion management, showing that the choice of a correct operating strategy can generate significantly larger benefits for the electrical system.","PeriodicalId":368119,"journal":{"name":"2015 AEIT International Annual Conference (AEIT)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124591033","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}

A statistical analysis is then performed on thousands of meshes representing the same sample geometry, with different inclusions distribution. Homogenization technique based on energy balance is then adopted in order to compute the effective permeability of the mortars. Thus, we are able to establish a relationship between the components of the mixture and an ideal equivalent homogeneous magnetic material with an assigned magnetic effective permeability.

The ABS also increase the system efficiency by recovering energy during train braking phase and making it available again at the next starting time, minimizing the energy required to the main substation. An extensive simulation framework is performed on a real Italian 3 kV DC railway system feeding a new generation high speed train where the ABS supports conventional supply system. The simulation results confirm the effectiveness of the ABS in terms of peak current reduction and voltage drops compensation.

Recent years have experimented a rapid evolution of power electronic components able to dramatically enhance the effectiveness of the active and reactive power flow management. The inverter diffusion makes possible the intelligent integration between systems with different characteristics (i.e. in terms of voltage magnitude and frequency) and the exploitation of generation sources and storage systems typically operating in DC. One of the most interesting components able to interconnect different portions of electrical networks is the Solid State Transformer. The Solid State transformer is formed by few static power converters that operate sinergically and are connected in series with a high frequency transformer. Different voltage levels are made available to achieve high results in terms of system integration, efficiency and flexibility. Taking advantages from the described component structure and main features, in this paper the authors aim to evaluate the main potentials of this technology if widely introduced in the main power system. Starting from the single component description, a couple of possible applications are presented and discussed in terms of assets and weak points.","PeriodicalId":368119,"journal":{"name":"2015 AEIT International Annual Conference (AEIT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121756371","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}
