In recent years, several innovative solutions for the traction drives have been proposed with the aim to increase the efficiency and the performance. Particularly interesting is the solution based on the double star chopper cell converter integrating the battery in the converter modules and implementing also the battery management system functionalities. For this converter, different modulation techniques have been proposed but all of them keeps the dc bus voltage constant implying the use of all the battery modules in any working moment. In this paper, the possibility to reduce the battery usage, and, therefore, their ageing, by controlling the dc bus voltage as function of the vehicle speed is analyzed. The proposed control technique is implemented in a numerical model and the obtained results show the possibility to increase, in a significant way, the battery lifetime with positive effects also on the vehicle range.","PeriodicalId":111104,"journal":{"name":"2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130830056","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 addition to innovative topologies, the use of emerging technologies of semiconductors is also crucial. In this context, using a three-phase interleaved dc-dc topology, a comparison between the use of SiC-MOSFET and Si-IGBT is presented in this paper, mainly in terms of operating efficiency. Two cases have been presented: 1) with the same inductor, where only power device losses have been considered; 2) with the same inductor current ripple, where different inductors have been considered and the analysis included also the inductor design and losses. The simulations were carried out in LTspice simulation tool on realistic dynamic models of power switch modules obtained from the manufacturer’s experimental tests. The results validate the use of SiC-MOSFET for the three-phase interleaved dc-dc topology showing lower losses for both the power devices and inductor and, most important, prove the advantages of its use in terms of efficiency for a wide range of operating powers.","PeriodicalId":111104,"journal":{"name":"2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128595467","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 Dual Active Bridge (DAB) is one of the most promising topologies of this kind, especially in interfaces to batteries. Investigation with different abstraction levels is often needed in these power converters design process, e.g. ideal behavior (steady-state, dynamics), losses analysis, optimization of parameters and control. In this paper, the theoretical steady-state model for Dual Active Bridge DC-DC converters is studied, considering all the possible modulation techniques, i.e. phase-shifts between all legs (all \"degrees of freedom\"). The analytical developments presented, based on the superposition principle, allow to obtain the waveforms of inductor and output current using a simple and fast closed-form procedure. This analytical approach can replace dynamical simulations when only steady-state behavior is to be analyzed, with much faster execution. This allows to apply optimization methods for the selection of the operating point or during the design stage (e.g. for selecting inductance and frequency values). Moreover, the novel fully analytical model describes the output current vs. phase-shifts relationship, which can be exploited for control design or characterization of the converter behavior. Simulations in PLECS Blockset validate the theoretical results.","PeriodicalId":111104,"journal":{"name":"2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132992175","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}

It has also been widely signaled as a source of malfunctions in power equipment the high values of humidity which create harmful condensation inside distribution stations. Most of the current solutions in the market for controlling the internal ambient conditions focus either on installing forced ventilation or increasing the amount of ventilation through the addition of more ventilation ports. This paper presents a solution to achieve an internal control of temperature and humidity by using only natural ventilation without recurring to either excessive ventilation or an active ventilation system. A prototype of an automated shutter is proposed. This prototype manages the amount of natural ventilation through the opening or closure of the ventilation grills. A working prototype was built and installed in two pilot distribution stations and the control algorithm was successfully simulated. This paper presents the prototype as well as the results of the tests carried out and the following conclusions.","PeriodicalId":111104,"journal":{"name":"2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116014952","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}

Additionally, increasing loads needs more capacity in the system and accordingly network expansion planning would be required. In this paper two aspects i.e. Microgrid aggregator and Energy Storage (ES) planning are integrated. It goes without saying that installing new ES capacities in the distribution level costs less than constructing new generators so considering ES, energy can be stored during extra production times and used when it is needed such that there is no need to pay for investment cost for new candidate components. Therefore, storing the extra production related to renewable resources is the goal of ES planning in this paper. An ES expansion approach in the presence of Microgrid aggregator is formulized linearly without using any approximation. Moreover, the effect of renewable resources such as wind turbines is considered and the effect of uncertainty related to renewable production in addition to load uncertainty are considered by a new stochastic model.A modified IEEE 6-Bus test system is implemented to illustrate the helpfulness of the presented model.","PeriodicalId":111104,"journal":{"name":"2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130245762","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}
