Prompt intervention in emergency cases is one of the key factors to minimize damages. Therefore, real-time surveillance is proposed as an efficient means to detect problems on roads. Video surveillance alone is not enough to detect serious accidents, since any hazardous behavior on the road may be confused with an accident, which may lead to many wrong alarms. Instead, audio processing has the potential to recognize sounds coming from different sources, such as crashes, tire skidding, harsh braking, etc. Since a few years, deep learning has become the state of the art for audio events detection. However, the usual dominance of absence of events in road surveillance would make a bias in the training process. Therefore, a novel method to initialize the neural network's weights using an autoencoder trained only on event-related data is used to balance the data distribution.","PeriodicalId":268311,"journal":{"name":"2020 IEEE 20th Mediterranean Electrotechnical Conference ( MELECON)","volume":"237 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":"116158469","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}

This paper proposes a local measurement based protection system for multi-terminal HVDC systems. Primary protection is based on rate of change of voltage (ROCOV) algorithm, while the backup and busbar protections are based on rate of change of current (ROCOC) algorithm. The performance of these algorithms is tested through simulation in PSCAD software. The proposed system is validated with different fault case scenarios, including low and high resistance fault conditions. The ROCOV algorithm provides the protection system of a fast, reliable and accurate primary protection against low and high resistance fault conditions. Meanwhile, the ROCOC algorithm is implemented in order to operate in case of primary protection failure. Its operation against low resistance faults is similar to the ROCOV performance, however, it presents low sensitivity to high resistance fault conditions. An overcurrent feature is implemented in order to improve the backup protection sensitivity and reliability. On the other hand, the busbar protection performance is fast, accurate and selective; it does not misdetect link faults.","PeriodicalId":268311,"journal":{"name":"2020 IEEE 20th Mediterranean Electrotechnical Conference ( MELECON)","volume":"402 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":"116658533","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}

But not only the drive train will be electrified but also the implements and attached equipment. This leads to new designs of these implements, which may require new control strategies. The electrified sickle-bar mower for cutting grass with mobile machines is shown here as an example. The aim is to control the amplitude of the sickle-bar’s position, which is important for a good process quality, but energy efficiency is also important for long operating times. The developed control strategies are able to control the desired position amplitude and the approaches have strategies to be energy efficient. One control strategy is based on the super twisting algorithm and the other controls the amplitude of a sinusoidal motion.","PeriodicalId":268311,"journal":{"name":"2020 IEEE 20th Mediterranean Electrotechnical Conference ( MELECON)","volume":"8 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":"131067844","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 context, typical residential installations consists of photovoltaic (PV) generation and batteries. Battery energy management poses a challenge because of the variability and uncertainty related to PV generation and customer consumption. Here, we propose easy to implement rules for the system (PV + battery) operation, to minimize the total cost for the customer. The main contribution is to use the rule-based operation for system sizing and operation, and to compare the results to those for an optimization based sizing and operation with perfect foresight. Based on this comparison, the value of information for the system operation is quantified and discussed. The optimization problem and the rule-based operation are applied to a case study for a residential customer in Southern Spain.","PeriodicalId":268311,"journal":{"name":"2020 IEEE 20th Mediterranean Electrotechnical Conference ( MELECON)","volume":"1 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":"126494779","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 properly consider the real system operation, the employed battery model is modified, in order to include also the hysteresis phenomena in state of charge estimation in both charging and discharging operation. The validation of the proposed methodology is supported by experimental tests which allow comparing two different battery models.
