In this regard, technical parameters of an existing CSP plant currently in operation in Ottana (Italy) have been adopted for analyses. The biomass combustion technology involves direct burning of solid biomass in a furnace, while the anaerobic digestion technology entails biogas production from fruit and vegetable wastes. For the two technologies, the biomass retrofit system was proposed to constantly supply 45% of the nominal thermal power demand of the power block. Results demonstrated the energetic and economic benefits arising from the hybridization of existing CSP plants, both in terms of enhancement of the plant capacity factor and reduction of the cost of energy. Preliminary economic analysis highlighted the direct combustion of solid biomass as a more cost-effective option, while anaerobic digestion biogas plant suffers from substantial installation costs.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"1 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":"129813477","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 photovoltaic inverters, losses are mainly contributed by switch losses, copper and magnetic losses and input capacitor losses in general. Reducing these losses step-by-step could help to achieve a high end to end efficiency (ETEE) in solar inverters. The proposed supercapacitor assisted sub-module inverter (SCASMI) technique proposed here is expected to reduce copper losses, magnetic losses and input capacitor losses by applying the supercapacitor assisted loss management concept to the traditional R-C circuit loop. This article presents the preliminary successful results of the SCAMI concept of dividing a single inverter into an even number of sub-inverter modules and coupling them with supercapacitor banks which theoretically reduces the input capacitor losses and the copper losses. Experimental results of the simplest case of dividing a 24 V DC to 240 V AC inverter load into two 12 V DC 120 V inverters with SC banks of nominal 12 V are compared with theoretical values.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"221 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":"122190116","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}

State-of-the-art in reduction of the circulating current indicates the ubiquitous use of filter inductors, which are placed at each parallel converter output. This paper presents a new control algorithm to remove those filters, relying only on the natural parasitic inductance at each connection point. Multiple cells in parallel are modeled to investigate the transient behavior of the load signals and their group dynamics in case of a large number of units. A two-step control strategy is proposed: a narrow-bandwidth communication interface is used to synchronize coarsely the units, then a high-speed closed-loop control on the converter current tracks the difference in samples taken by the Double Edge Sampler (DES). Correction is achieved by means of high-resolution parametric delays, cascaded to the traditional PWM modulator. Each converter controls its own current without the need of information from his neighbors. The potential of this technology is envisioned in the automotive field, where modular powertrains can be designed for different vehicle targets. The effects of the proposed approach can improve power per unit of volume and weight, thanks to the removal of the bulky output filters.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"127 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":"132269307","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 order to reduce the charging time, high power chargers are necessary. However, lithium-ion chemistry limits the maximum current and charging speed. The diffusion rate of lithium ions into the electrodes determines the rate of charging. The slow lithium diffusion, especially experienced after high current rates, inevitably results in concentration polarization. The increase of the concentration polarization, in addition to the growth of the charging time, may lead to a faster battery deterioration. To deal with this obstacle, the Pulse Charging (PC) protocol has been proposed. There is no common opinion about the benefits given by the PC to the battery charging process in comparison with the conventional constant-current, constant-voltage (CCCV) protocol. Nevertheless, the purpose of this work is to provide an overview of possible methods that can be used to generate current pulses, without focusing on its advantages. Different techniques with the corresponding control algorithms have been implemented and analyzed through simulations in MATLAB/Simulink environment.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"22 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":"114646521","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}

However, the reactance variation caused by non-negligible influence of switches' parasitic capacitor and practical load change will decrease the system reliability and degrade the system performance, such as zero voltage switch (ZVS) condition, efficiency and constant source feature. In this paper, a reactance compression design method achieved by rectifier input impedance analysis is detailed introduced by principle. In addition, an optimization algorithm for determining the circuit parameters is developed based on the proposed principle. Finally, comparisons between proposed reactance compression design method and traditional design method are implemented through wide load variation tests ($5-50 Omega$) with maximum 20 W dc output power. The results show that the design method proposed in this paper can achieve a significant reactance compression effect and improve the system performance while the load variation.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"42 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":"114419747","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}

At the same time, issues like safety and charge unbalance in batteries with series-connected cells may limit the full exploitation of the technology, as charge unbalance reduces the usable capacity of the battery. This work describes a passive cell equalization procedure executed by the Battery Management System that reaches the balance of the battery with negligible additional costs. It is based on an iterative algorithm that progressively reduces in small consecutive steps the charge levels of the most charged cells by activating bleeding resistors. The algorithm takes into account the inaccuracies of the measurement of the cell voltages, the maximum possible balancing power, and reduces the effect of the cell short-term relaxation phenomena. It is fully parametric and can be tailored to any kind of battery. The algorithm is experimentally validated with a 10-cell Li-ion battery and its functionality is successfully demonstrated.","PeriodicalId":262855,"journal":{"name":"2020 2nd IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES)","volume":"52 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":"116709565","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}
