Protection devices isolate a portion of the network affected by a fault, while control devices reduce the number of de-energized loads by transferring loads to neighboring feeders. The integration of distributed generation has the potential to improve the continuity of energy services through islanding operation during outage conditions. In this context, this paper presents a multi-objective optimization approach for the size and allocation of protection and control devices in distribution networks with microgrids supplied by renewable energy sources. Reclosers, fuses, remote-controlled switches, and directional relays are considered in the formulation. The demand and generation uncertainties define the islanding operation and the load transfer possibilities. A genetic algorithm is presented to solve the allocation problem. The compromise programming is performed to choose the best solution from the Pareto front. Results show interesting setups for the protection system and viability of islanding operation.","PeriodicalId":303656,"journal":{"name":"2022 IEEE 21st Mediterranean Electrotechnical Conference (MELECON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129889158","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}

On the bright side, the increased controllability of the Voltage Source Converters used as an interface of the CI-DRES with the grid together with the use of fast-acting Energy Storage Systems- such as Supercapacitors (SCs)- enable the CI-DRES to provide Ancillary Services (AS) to the grids. Since the majority of CI-DRES depends on a primary source with intermittent characteristics (wind, solar irradiance, etc.), a possible AS is the Ramp-Rate Limitation (RRL) of the active power of the CI-DRES primary source. This action is also referred as power smoothing. Several control strategies have been proposed in the technical literature, each of them having different advantages or drawbacks. This paper presents a parametric evaluation of the power smoothing control strategies which employ a SC. The parameters analyzed are the involved purchase cost, the measurement time window of the smart meters used within the electric power systems and the finally achieved RRL.","PeriodicalId":303656,"journal":{"name":"2022 IEEE 21st Mediterranean Electrotechnical Conference (MELECON)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128365731","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 our study, we applied a stress test on a treadmill with the regulated speed and incline. Because traditional parameters describing physical performance (heart rate, blood lactate concentration, VO2max) do not provide specific information about muscle activity, an alternative approach is needed. Such information may be derived from the analysis of electromyograms (EMG signals) in the frequency domain–in the form of median frequency (MDF). The changes of MDF were analyzed for four phases of the experiment: the initial state, walking with the velocity of 4 mph (6.44km/h), walking with the highest walking velocity (4.5-6 mph; 7. 24-9.66km/h), and the rest. The coefficients of linear regression (slope and intercept) indicate the decrease of median frequency of the EMG signal during phases 2 and 3 and the increase of MDF during the rest. Observed values of linear regression of the median frequency of surface EMG during the analyzed phases indicate the usefulness of such analyses in evaluating muscle fatigue, which may find its use in monitoring the interval training.","PeriodicalId":303656,"journal":{"name":"2022 IEEE 21st Mediterranean Electrotechnical Conference (MELECON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125165498","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}

HOLOBalance is an interactive AR rehabilitation system which encompasses multi-sensory training program to enhance balance and cognitive coaching, for older adults at falls risk. In this work, we present a sentiment analysis of the patients participating in this study using the VADER methodology to evaluate and quantify their attitude towards the HOLOBalance system. Our results highlight the importance of findings positive polarity towards the AR interaction, which is based on the use of a holographic virtual physiotherapist.
