These vehicles operate under dynamic load conditions such as frequent acceleration, breaking, and regenerative events, which demand high-performance power management.

Vinod Kumar,&nbsp;Aneesa Farhan M.A.","doi":"10.1016/j.est.2025.118585","DOIUrl":"10.1016/j.est.2025.118585","url":null,"abstract":"<div><div>The global transition towards Electric Vehicles (EVs) necessitates the widespread deployment of Electric Vehicle Charging Stations (EVCSs), which, while enhancing energy security and reducing carbon emissions, also pose significant challenges to the distribution network (DN). Key concerns include voltage deviations and increased active power losses due to the high penetration of EVCSs. This study proposes a comprehensive multi-objective optimization (MOO) framework for the optimal integration of EVCSs and shunt capacitors (SCs) within the DN, while simultaneously considering the dynamics of the transportation network (TN). To ensure an efficient and sustainable charging infrastructure, a Driving Range-based Traffic Flow Capturing (TFC) model is employed to optimize EV traffic flow coverage, accounting for EV battery constraints and strategic station placement. The proposed framework aims to minimize active power loss (APL) and voltage deviation (VD) in the DN while maximizing EV flow in the TN. To solve this complex multi-objective problem, a novel hybrid metaheuristic algorithm (HGCO) is developed by integrating Grey Wolf Optimization (GWO) with Cuckoo Search Optimization (CSO). Objective function normalization is applied to balance the conflicting goals between the DN and TN. The proposed framework was tested on a 33-bus DN and a 25-node TN under three different planning approaches: one focusing on the DN, another on the TN, and a third on their integrated operation. In the integrated planning case, the system recorded an APL of 161.3842 kW and captured 39.45% of electric vehicle flow when battery constraints were applied. Upon removing these constraints, performance improved significantly, with the APL decreasing to 148.5903 kW and EV flow capture rising to 50.52%. Simulation results demonstrate that the proposed HGCO algorithm effectively balances power system reliability and transportation service efficiency. This integrated planning approach highlights the importance of coordinated EVCS and SC placement in realizing a resilient, efficient, and sustainable electric mobility infrastructure.</div></div>","PeriodicalId":15942,"journal":{"name":"Journal of energy storage","volume":"138 ","pages":"Article 118585"},"PeriodicalIF":8.9,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145270524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimized process produces MSeO₃ with high lithium storage capacity (2459.6 mAh g⁻¹ at 0.2 A g⁻¹ for 400 cycles), remarkable high-current charge/discharge capability (15 A g⁻¹), and excellent cycling stability (1500 and 1740 cycles at 5 and 10 A g⁻¹, respectively) when used as a lithium anode. Cyclic voltammetry (CV), in-situ Raman spectroscopy, ex-situ transmission electron microscopy (TEM), and X-ray diffraction (XRD) confirmed the decomposition of TMS during the first lithiation to form metal oxide and selenium oxide heterostructures. The reduction product metal monomers were found to be involved in an irreversible alloying process, which leads to capacity decay in the initial stage, using dQ/dV and post X-ray photoelectron spectroscopy (XPS). Subsequently, selenium oxide dominates, leading to an increase in specific capacity. Density functional theory (DFT) calculations suggest that the mismatched band structure of these materials may cause the capacity fluctuations prevalent in TMS.
