Lithium battery is considered in EOL if at 85-80% of nominal capacity. Today, the reusing of Electric and Hybrid Vehicles EOL batteries on less-demanding grid connected energy storage applications, giving them a second use/life, is an interesting solution to reduce high potential cost of lithium batteries. Currently, there is a lack of investigation of the performances of these second life batteries. In this paper, authors show the results of the impedance spectroscopy of 20 Ah lithium NMC batteries after EOL, exactly at 100, 85, 80, 60 and 50% of rated capacity, in a wide range of frequency: 450 mHz to 3.5 kHz. By results, there are many way to correlate battery state of health and battery impedance spectroscopy, especially when the battery is in second life.","PeriodicalId":215332,"journal":{"name":"2020 IEEE International Conference on Environment and Electrical Engineering and 2020 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"23 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134411333","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 validate the approach, a set of experimental tests have been carried out on a real LV microgrid considering different configurations. Results show the effectiveness of the proposed technique and applicability to dynamic simulations.","PeriodicalId":215332,"journal":{"name":"2020 IEEE International Conference on Environment and Electrical Engineering and 2020 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"91 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133391433","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 P2P (Peer to Peer) Electricity Market is expected to be a solution when accumulator-users play an important role. In such background, widespread EVs are expected to participate in the P2P market and utilize the battery storage. However, in previous research, only simulation and effect verification under an ideal condition were conducted and no EV bidding agent which works in the real situation was proposed. Therefore, in this paper, a whole system of a robust automatic bidding agent of EV which works in the real situation is proposed, and case studies based on the actual EV driving data were conducted. The results show that even EVs are running irregularly, proposed EV bidding agent was able to realize benefits for EV-users and leveling effect of the power demand through the day.","PeriodicalId":215332,"journal":{"name":"2020 IEEE International Conference on Environment and Electrical Engineering and 2020 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115029486","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}

One of the main contributions of this article is to identify the demands patterns at any time intervals (the day, month, and year) to adjust the power generation's schedules and prevent any disturbances due to the consequences of charging a massive amount of EVs in the same time. The output shows that energy consumptions are highly correlated to the weekdays; for instance, generally, the Thursdays and Fridays are considered as a high peak while weekend-days and holidays are the minimums.","PeriodicalId":215332,"journal":{"name":"2020 IEEE International Conference on Environment and Electrical Engineering and 2020 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114670301","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}

EMF may induce various effects: in the case of direct short term effects, static and low-frequency fields interact with the biological tissues through the induction of currents, while high frequency fields through thermal mechanisms. EMF can also induce indirect effects, as interference, causing a specific risk e.g. in workers with active medical devices as pacemakers. The induction of various long term effects has also been proposed, but up now data supporting a causal effect are considered insufficient by almost all authoritative international agencies. Moving to OR, sources can be artificial (incoherent or coherent in the case of LASER) or natural; the main source of occupational OR exposure is natural: the Sun, exposing millions of outdoor workers worldwide. The main targets of OR effects are the skin and the eye. Among OR bands, the ultraviolet component is of particular relevance, inducing photochemical alterations in human cells that can cause both acute and long term effects as burns and skin cancers or cataract. For all workers NIR risk should be evaluated and, in case of significant risk, an adequate health surveillance (HS) should be implemented, also considering the possible presence of workers with conditions inducing a higher susceptibility to the risk, as subjects with active medical devices for EMF or subjects with a fair skin photo-type or eye alterations as aphakia or aniridia for OR. Aims of HS of occupational NIR exposure are the prevention and early detection of related health effects. The appropriate specific HS content depends on the NIR band(s) and on the specific work activities but, in general, at least a screening of the conditions inducing a particular risk and an active seeking of symptoms possibly induced by exposure should be performed before of the employment, and periodically repeated.","PeriodicalId":215332,"journal":{"name":"2020 IEEE International Conference on Environment and Electrical Engineering and 2020 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114822365","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}
