The value of lost load (VoLL) is a monetary indicator expressing the costs associated with power supply interruption in €/MWh. This paper quantifies the VoLL of Italian consumers through outage cost surveys, following the adoption of the EU Clean Energy Package which introduces a new methodology for measuring VoLL. The results of the study confirm that the concept itself of VoLL has many limitations and that its direct usage for investment decisions (e.g. Capacity Markets design, Cost Benefit analyses, …) must be carefully weighted. This intrinsic limitation of the VOLL concept will be more and more relevant in the years to come, when – as a consequence of progressive electrification of final energy uses – our quality of life will be almost completely dependent on 24/7 power availability.","PeriodicalId":253384,"journal":{"name":"2022 AEIT International Annual Conference (AEIT)","volume":"4 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":"129920180","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 this reason, the early testing of such technologies in realistic grid conditions play an important role.

They present themselves as an innovative entity in the national and international energy landscape capable of contributing to the energy transition process through locally produced energy, its self-consumption and sharing with energy community users. Local energy communities are considered an empowerment tool for end users who take charge of the distributed production and management of the energy asset, but in order for the energy asset to be put to its best, most efficient and effective use, it is necessary to develop key performance indices that are also easily understood by community members, whether they are elderly, young people, private companies, public entities, etc., and to which it is immediate to react with proactive behaviour in order to maximize their economic benefits, which, of course, translate locally into environmental and social benefits. In this context, the manuscript presents some performance indices that can be used to achieve the above goals. An energy community case study is discussed to show the purpose and usefulness of the proposed metrics.","PeriodicalId":253384,"journal":{"name":"2022 AEIT International Annual Conference (AEIT)","volume":"520 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":"123131176","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, the distribution grid may not be always capable to provide such high levels of power in every area. From this prospect, recharging pools equipped with battery storage system provide the opportunity to limit the maximum power request to the grid, avoiding the need for an upgrade to the grid connection. This solution can be implemented by means of various configuration depending on the storage system size and the relative energy management, leading to different costs. This paper carries out a technical and economic analysis of a high-power recharging pool connected to the low voltage distribution network and equipped with a stationary storage system. A simulation model developed in Modelica language is used to compare three different storage configurations. Results indicate that a peak shaving BESS is the most feasible solution. It is also observed that a reduced size would improve the profitability of the investment, supporting the EV recharge with a reasonable additional waiting time.","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":"126314637","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 literature, works on single phase SPEC related to operating principle, limitations and devices control for compensation of network voltage under load and renewable energy variations are presented. However, works related to its active power management to meet its device losses are often not considered and seldom presented in the literature.

Carried out studies evidenced the crucial importance of the Tyrrhenian Link project in the next future to guarantee the adequacy standard for Sicily and Sardinia, considering the forthcoming coal phase-out and avoiding further new thermoelectric capacity in these Regions. Moreover, static and dynamic analyses emphasize the essential contribution of the new planned project both to the dynamic stability and to the security of supply in case of HV grid contingencies, showing the fundamental role of this new project for the Italian electrical system of the future.
