A proper modeling of the hydrogen-based microgrid has been developed and the expected performance in terms of annual hydrogen production and postponed use in the fuel cell have been analyzed. A preliminary economic analysis has been finally conducted for investigating the cost-effectiveness of integrating hydrogen production plants in facilities provided by photovoltaic plants and characterized by low electric demand during the weekends.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"109 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":"116160391","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}

Storing energy for temporary basis in batteries is not an effective solution for applications demanding instant high current. Batteries due to their limited cycle and calendar life as well as disposal issues make them less attractive in many renewable applications. Introducing supercapacitors as short term energy storage devices is a viable solution to overcome the above problems. Supercapacitor (SC) assisted low drop-out regulator (SCALDO) is a very low frequency DC-DC converter technique, with high end-to-end efficiency, where the load receives a high slew rate capable low noise output of a linear regulator. In this hybrid DC-DC converter, a switched-mode SC assisted input stage reduces the overall switch count of SCALDO and this helps to reduce switching losses at very high input to output voltage ratios. A series supercapacitor is introduced in the input loop with the transformer providing isolation and SC acts as an electronic shock absorber. Series SC is also acting as short term DC-UPS for the power converter. This paper provides an overview of this novel hybrid power converter, discusses control strategy in detail. Experimental results and simulation outcomes are presented to prove the technical feasibility of the concept.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"356 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":"116241017","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 kind of BMSs is intrinsically different from those of solid-state batteries, due to the very different battery operating principle. Such BMS was built entirely in-house around a desktop computer provided with LabVIEW software which results in an expandable and flexible system capable of providing the battery with SCADA functions. It acquires and processes all data generated by the thermo-fluid and electric sensors, which are necessary to carry out the subsequent analyses. Moreover, this BMS also creates the feedback signals for controlling every operation, including experiments such as polarization curves plotting and efficiency computation. As regards polarization curves, this algorithm implements an experimental protocol that allows to obtain such performance in reproducible conditions and possibly comparable with those of similar stacks. The efficiency computation algorithm computes the energy absorbed (or delivered) by the battery while acquiring and controlling all signals so as to ensure safe conditions. The management of signal between stack and BMS includes the galvanic insulation of cell and stack voltages, consisting of multiple opto-isolators and a DC/DC transformer.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"28 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":"133277033","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}
