Terna is the largest independent electricity transmission network operator in Europe and one of the world's leading operators in terms of the number of kilometres of overhead line managed, with around 72,900 kilometres of high-voltage lines. These lines cover a quite extensive area and are therefore constantly subject to weather events. In some cases it is necessary to switch off the line to manage dangerous situations. In the last few years, extreme weather events have been getting more and more frequent due to climate change. Dry weather and high temperatures increase the wildfire risk close to high-voltage overhead lines. In this context, the procedures for manage the event involve actors (Terna, fire fighters …), several of them not electrical operators; the article describes the procedure, including in the Annex of the Italian Grid Code, and specific issues that have emerged from the operating experience, to coordinate all operators during dangerous situations. The procedure is the result of an agreement between Terna and the other operators, such as the Italian Civil Protection Agency.","PeriodicalId":134409,"journal":{"name":"2019 AEIT International Annual Conference (AEIT)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114289086","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 growing availability of reliable and cost-effective ICT solutions are indeed offering the opportunity for the implementation of advanced monitoring and control functions over Distributed Energy Resources (DERs), thus fostering the transition towards decentralized and decarbonized energy systems. The integration of ICT in electrical equipment (such as power converters, metering devices, and protections) is essential for the monitoring and the coordinated control of heterogeneous energy resources, particularly in intermittent and distributed scenarios. Nevertheless, the implementation of such control approaches relies, in the end, on the availability of proper communication infrastructures. The adoption of wired infrastructures (such as field-bus, ethernet, or fiber optic systems) may however imply high installation costs, particularly for complex end-users' systems. To cope with this issue, in this study the use of a wireless network based on the LoRaWAntechnology is proposed to implement the monitoring and the coordinated control of dispersed DERs. A proper communication architecture is proposed and discussed in terms of the required coverage range and latency. Finally, a scalability analysis is also presented, which aims at evaluating the number of devices that can be supervised by a single LoRaWAngateway, by considering the expected data throughput, and the duty cycle limitations.","PeriodicalId":134409,"journal":{"name":"2019 AEIT International Annual Conference (AEIT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125052219","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}

It defines testing scenarios, experimental setups, data post-processing procedures and the limit values to be respected by a number of different parameters, mainly associated with vehicle safety. The key role of the entire homologation process is represented by the instrumentation setup and the measurement chain, which are essential in getting accurate parameters which has to represent physical quantities with only marginal uncertainties. Among all the measured parameters, contact forces between the train wheelset and rails retain a significant importance in the Normal Method, requested by the standard. Since, unlike other physical quantities (e.g. accelerations or displacements), contact forces cannot be measured directly during train rides, it is nodal to have a consistent and coherent theoretical model to correlate measurable quantities such as strains and displacements measured on wheelsets with real contact forces. Following this approach, it is crucial to have a robust and reliable measurement chain able to acquire right values of those quantities and transfer them on the elaboration unit. The scope of this paper is hence to present a brief overview of this measurement chain, of the solutions adopted with its points of strength and the encountered issues. In conclusion, future developments of the system will be briefly hinted at.","PeriodicalId":134409,"journal":{"name":"2019 AEIT International Annual Conference (AEIT)","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130351517","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 this work, the supply, by EVs, of balancing services on the Italian Balancing Market (BM) is simulated, to inquire the related possible profitability for the EV owners. More precisely, for a domestic and a non-domestic end user, with different recharge needs, the EV electricity bill related to supplying the service - in a one-directional (V1G) or bi-directional (V2G) way - while recharging is evaluated, in comparison to carrying out standard (“benchmark”) recharge where energy is assumed to be bought at day-ahead market prices. A sensitivity analysis of the results is carried out, by adopting different (although constant) prices to bid for the service. With the V2G recharge, the increased energy exchanges, with respect to the V1G and to the benchmark recharge, can yield increased bills due to the charges and taxes on such exchanges. However, both for the V1G and for the V2G recharge, price regions are found for which the service can be deemed to be profitable, i.e. with the bill lower than or equal to the benchmark bill. The profitability price regions are widened, and the maximum saving with respect to the benchmark bill is increased, if partial reliefs from charges in the bill and/or an additional remuneration for capacity availability are introduced.","PeriodicalId":134409,"journal":{"name":"2019 AEIT International Annual Conference (AEIT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130449834","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}
