Several considerations must be done about the Safe Operating Area of a battery, that means maintaining the correct levels of voltage, temperature and current, as well as avoiding main power cuts due to system faults. This article proposes an FPGA implementation of a Triple Module Redundancy extension for a conventional BMS. The design of the hardware accelerator is described, the testing set-up is introduced and the results of the experimental validation process are discussed. The FPGA accelerator successfully demonstrates the full functionality and the advantages achievable by its introduction in the Battery Management System (BMS) architecture.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122124784","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 bear that, high speed electrical machines represent a mature technology in different application fields, e.g. avionics, automotive, compressors and spindles. In order to guarantee high speed while keeping high power quality without adopting bulky filtering circuits, DC-AC converters shall be controlled by means of high Pulse Width Modulation (PWM) frequencies. In addition to the emerging switching device technologies, such as those based on Silicon-Carbide (SiC) and Gallium-Nitride (GaN), alternative circuital topologies are crucial in order to comply with the higher switching frequencies while maintaining high voltage levels. The Cascode (CC) structure represents an attractive topology for those applications. In this paper a three phase inverter based on CC devices is investigated, by simulating a 400 Hz sinusoidal PWM. Experimental results showing the satisfactory operation of a single-switch DC-AC implemented through a CC architecture are provided as well.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122204435","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 experiment consists of a sequence of full charge/full discharge cycles, with constant current and constant voltage phases for the charge and the discharge. The main difference between the tests conducted over the two batteries is the rest time after charge in each cycle. For one battery, this time is one hour, while for the other one is one minute. The analysis is performed in terms of capacity, charge-discharge times, voltage evolution during the rest period and internal resistance. The results show that, in terms of the characteristics analyzed, there is not a considerable difference in the degradation behavior of the two batteries, which may mainly be due to the relatively-short length of the rest periods with respect the time constants related to phenomena, such as the capacity recovery.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120837326","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}

While the dynamics of the coupling inductance is sometimes also taken into account, the grid dynamics are almost always neglected. However, as the neglected interplay of the controllers through the grid can be crucial, a stable overall power system can not be guaranteed. To address this problem, we derive a sufficient condition for the stability of the overall system which can be considered during the common decentralized design procedure. We propose a new, simpler control structure for voltage control, which has more degrees of freedom than the conventional control structures. Based on an exemplary microgrid, we demonstrate how the control parameters can be designed decentrally using our stability condition. Simulations finally show that the decentrally designed controllers indeed yield a stable and robust overall system. Our results can also be applied in order to ascertain the stability of energy networks consisting of coupled microgrids.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"235 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133038592","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 impact of threshold voltage and current factor statistical fluctuations on energy dissipation during hard switching conditions is evaluated by means of Monte Carlo ET simulations.

The operating conditions exhibit very fast dynamics (e.g., the battery current of an electric vehicle) as well as moderately slow ones (e.g., the ambient temperature variation). Because of the huge time-scale differences between the capacity fade phenomenon and the battery usage waveforms, it is very difficult to compact the waveform information and to predict the actual capacity. It is therefore necessary to extract a minimal set of indicators that are useful for the capacity estimation. For this reason, we analyse the possibility of using the battery internal resistance as a predictor for the estimation of the residual capacity. The analysis is carried out for Lithium Cobalt batteries continuously operated with random current patterns and in pulsed current tests, where the influence of the state of charge can be neglected. The results show that a linear correlation between the internal resistance and the capacity can be established, so that it is possible to use the resistance to assess the residual capacity.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124257844","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}

A typical building consisting of 20 apartments and an elevator used to have a standby electric generator of about 60 to 100 kVA rating. The only control used in managing such a shared back-up system is through installing circuit breakers to limit the maximum current drawn by each apartment. Consequently, residents tend to consume the maximum allocated energy resulting in oversizing backup systems and squandering valuable energy resources. The situation becomes worse when the backup system comprises an off-grid photovoltaic (PV) system. A practical PV system on the roof of a typical building is in the range of 10kW making it hard to share without a smart management system. In this work a pricing policy is proposed for efficient management of such a shared power supply. This policy will be implemented using a programmable logic controller (PLC) accessible to the residents through a local area network to monitor their consumption and status on line. It is expected that this new system will add positively to residents' satisfaction, fairness, and efficient power utilization.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"376 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124697783","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}
