摘要

为了应对日益增长的减少温室气体排放和实现脱碳社会的需求,本研究重点研究了可再生能源驱动的电动汽车充电站的优化设计。纯电动汽车(bev)在运行过程中不排放二氧化碳,与停车换乘(P&R)系统相结合,尤其有效,可以缓解城市交通拥堵。本文研究了日本冲绳县P&R纯电动汽车充电站的优化运行和配置,比较了光伏发电(PV)、风力发电(WG)和电池储能系统(BESS)两种并网和离网供电方式。在满足电动汽车充电需求的同时,建立了年运行成本最小的多目标优化模型。为了确定最优配置,对设备单元组合进行了穷举搜索。由此产生的帕累托前沿揭示了电动汽车年充电总能量与停车运营商利润之间的权衡。此外,还详细分析了三种具有代表性的收费水平。结果表明,在适度的充电需求下,并网系统实现了更高的利润率,利用电网电力保持稳定运行。相比之下,离网系统虽然需要更高的初始投资,但在高需求场景或电网接入有限的偏远地区表现出更大的自给自足能力。因此,应根据电动汽车充电规模、区域基础设施、弹性要求等具体情况选择最优供电方式。在这些方案中,并网系统被认为是在当前技术和制度条件下最实际、最经济可行的解决方案。

Multi-Objective Optimization of On-Grid Park and Ride EV Parking Station With Renewable Energy
In response to the growing need to reduce greenhouse gas emissions and achieve a decarbonized society, this study focuses on the optimal design of electric vehicle (EV) charging stations powered by renewable energy sources. Battery electric vehicles (BEVs), which emit no CO2 during operation, are particularly effective when combined with Park and Ride (P&R) systems that mitigate urban traffic congestion. This paper investigates the optimal operation and configuration of P&R BEV charging stations in Okinawa, Japan, comparing two power supply methods: on-grid and off-grid systems using photovoltaic (PV), wind power generation (WG), and battery energy storage systems (BESS). A multi-objective optimization model is developed to minimize the annual operating cost while meeting EV charging demand. To identify the optimal configuration, an exhaustive search of equipment unit combinations is conducted. The resulting pareto front reveals trade-offs between total annual EV charging energy and parking operator profit. In addition, three representative charging levels are analyzed in detail. Results show that on-grid systems achieve higher profit margins under moderate charging demand, leveraging grid power to maintain stable operations. In contrast, off-grid systems, while requiring higher initial investment, exhibit greater self-sufficiency and perform better in high demand scenarios or in remote areas with limited grid access. Thus, the optimal power supply method should be selected based on site-specific conditions, such as EV charging scale, regional infrastructure, and resilience requirements. Among the options, the on-grid system is identified as the most practical and economically viable solution under current technological and institutional conditions.

期刊介绍: IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
