Abstract

This work proposes a methodology to assess the impact of electric vehicle (EV) charging on Lisbon's electricity distribution network, utilizing real load diagrams by postal code and a genetic algorithm to model the baseline and added EV load at substations. The method enables geographic mapping of EV charging to specific substations. Results show that increased EV charging significantly increases power flow, line overloads, and system losses. A fivefold increase caused some lines to exceed 100 % capacity, while a thirtyfold increase led to peak loads at 223 % and losses rising by up to 274 %. Bus voltage levels remained stable across scenarios.

模拟电动汽车充电对里斯本配电网络的影响

这项工作提出了一种评估电动汽车（EV）充电对里斯本配电网络影响的方法，利用邮政编码的真实负荷图和遗传算法来模拟变电站的基线和增加的电动汽车负荷。该方法可以实现电动汽车充电到特定变电站的地理映射。结果表明，增加电动汽车充电显著增加了功率流、线路过载和系统损耗。5倍的增长导致一些线路的运力超过100%，而30倍的增长导致高峰负荷达到223%，损失上升高达274%。母线电压水平在不同情况下保持稳定。

期刊介绍： Utilities Policy is deliberately international, interdisciplinary, and intersectoral. Articles address utility trends and issues in both developed and developing economies. Authors and reviewers come from various disciplines, including economics, political science, sociology, law, finance, accounting, management, and engineering. Areas of focus include the utility and network industries providing essential electricity, natural gas, water and wastewater, solid waste, communications, broadband, postal, and public transportation services. Utilities Policy invites submissions that apply various quantitative and qualitative methods. Contributions are welcome from both established and emerging scholars as well as accomplished practitioners. Interdisciplinary, comparative, and applied works are encouraged. Submissions to the journal should have a clear focus on governance, performance, and/or analysis of public utilities with an aim toward informing the policymaking process and providing recommendations as appropriate. Relevant topics and issues include but are not limited to industry structures and ownership, market design and dynamics, economic development, resource planning, system modeling, accounting and finance, infrastructure investment, supply and demand efficiency, strategic management and productivity, network operations and integration, supply chains, adaptation and flexibility, service-quality standards, benchmarking and metrics, benefit-cost analysis, behavior and incentives, pricing and demand response, economic and environmental regulation, regulatory performance and impact, restructuring and deregulation, and policy institutions.
