Here, the Single Particle Model (SPM) is considered, which mathematically describes the battery internal governing phenomena by means of parabolic partial differential equations (PDEs), but whose parameters are notoriously difficult to measure or estimate. After suitable approximation of this model through a linear finite-dimensional model, a systematic procedure of SPM calibration is here proposed and validated against real data issued from battery cycling in an electric vehicular application, i.e., under standard driving cycle scenarios. In a novel approach of SoC estimation, the suitably calibrated SPM, together with measures of voltage and current, allow to analytically connect the internal spatially distributed ions’ concentrations to the equilibrium concentration, which, at its turn, is an image of battery SoC. Results suggest that SPM can reliably predict the battery internal ions’ concentrations and be further used for SoC accurate estimation.</p></div>","PeriodicalId":37894,"journal":{"name":"IFAC-PapersOnLine","volume":"58 13","pages":"Pages 23-30"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2405896324005536/pdf?md5=8506a41a226fd7fd5de3e0f3a8fc5ac9&pid=1-s2.0-S2405896324005536-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141992632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper explores the novel trend of evaluating the social impact of last-mile delivery, emphasizing factors such as road safety, congestion, and noise pollution. A key strategy that has garnered attention in addressing these multifaceted concerns is Of-Peak Hours Delivery (OPHD), which involves scheduling deliveries during non-peak hours, often in the evenings or at night. This study investigates implementing a city-wide policy inspired by OPHD, strategically encouraging or discouraging deliveries in specific urban areas and time slots. The objectives of such a policy span from environmental considerations to nuanced social factors, potentially leading to dynamic shifts in time slot preferences. Adopting such a policy aligns with the growing citizen concern for environmental and social issues, leveraging changing attitudes toward sustainable practices. To evaluate this policy, we formalize it as a bi-objective mixed-integer programming model, aiming to strike a balance between the economic interests of retailers and the municipality’s overarching goals. Through realistic instances, the paper offers managerial insights, providing valuable perspectives on the practical effects of the proposed policy on delivery operations. This facilitates a deeper understanding of the ramifications of integrating social considerations into the optimization framework.</p></div>","PeriodicalId":37894,"journal":{"name":"IFAC-PapersOnLine","volume":"58 2","pages":"Pages 186-191"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2405896324001952/pdf?md5=104491fcf283b2b725668e131e3021bb&pid=1-s2.0-S2405896324001952-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141992719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This provides insight in how each planned component should be used to optimize revenues. The analyses show the importance of using hourly timeseries as input, as certain processes are operated in close alignment with periodic fluctuations in electricity prices or heat demand. Parameters are varied to evaluate the robustness of the investment decisions. The optimization results show that the studied CHP plant could transform to an energy hub, benefiting from synergetic effects when coupling multiple energy sectors using Power-to-X technologies.
