Traditional services for grid monitoring such as Phasor Measurement Units (PMUs) and Phasor Data Concentrators (PDCs) require a centralized architecture and a rigid networking infrastructure in order to properly function, which today is only achieved at the High Voltage (HV) transmission level. Furthermore, manual intervention is often the only option for PMUs/PDCs maintenance. In this work, the traditional PMU/PDC services were deployed as docker-containers in a decentralized Kubernetes cluster, which can represent any kind of geographically dispersed TCP/IP network. By leveraging remote orchestration, several key benefits are achieved: (1) no manual reconfiguration of the PMU-PDC communications upon network reconfiguration, (2) automatic PMU traffic redirection in case of PDC service redeployment in a different location, and (3) reduced data-loss upon PDC failure and enhanced overall system resiliency due to minimized ICT services down-time.","PeriodicalId":253384,"journal":{"name":"2022 AEIT International Annual Conference (AEIT)","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123683381","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}

To ensure a reliable operation of railway transportation, it is necessary to investigate the effects of lightning transients on the system and to design effective protection measures. The present study focuses on the 2×25 kV 50 Hz italian railway system. The system is modeled according to the Multiconductor Transmission Line (MTL) approach. Numerical simulations were carried out through EMTP. They aim at analyzing the distribution of direct lightning current and transient voltage on pole and catenary of the railway system. Surge arresters are modelled in order to mitigate the effects. Their response is discussed.","PeriodicalId":253384,"journal":{"name":"2022 AEIT International Annual Conference (AEIT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129252510","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 hierarchical approach has been implemented to estimate the available rooftop surface feasible for photovoltaic generation starting from the building area. Some factors such as the type of rooftop, the area already occupied by other rooftop elements, shading effects, etc., are considered in the calculation. Moreover, the potential photovoltaic production is computed using solar radiation data and the expected PV energy production and power installed. Modules and system conversion efficiency, orientation etc., are considered. The methodology has been tested in the real case of Milan, Italy, using open-source data available on government websites and technical information related to the specific case study.

However, RECs are still far from affecting the dominant energy regime. Hence, the present paper aims to investigate key enabling or disabling factors in REC-building processes and to facilitate multi-stakeholder mutual learning and capacity building. Under the chosen research design, single case studies have been complemented with a review of regional policy frameworks to account for the interplay between territorial differentiation and rapidly evolving social practices. Preliminary results point to the influence of local development trajectories on REC-building strategies, in line with the interdependency between context and agency. Further investigation of regional renewable energy policy frameworks is required to dwell on their interactions with bottom-up REC-building processes, to refine energy transition theories with a due consideration of territoriality and spatial differentiation.","PeriodicalId":253384,"journal":{"name":"2022 AEIT International Annual Conference (AEIT)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121384413","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}
