智能城市电网中的超快速充电站:综述

Integrating Ultra-Fast Charging Stations within the Power Grids of Smart Cities: A Review

Danielle Meyer, Jiankang Wang

摘要:

插电式电动汽车(PEV)已成为推动智慧城市的关键因素,它可以提高能源效率,降低对城市部门的环境影响。未来PEV的行业愿景包括以与传统天然气加油相当的速度对车辆进行再充电的能力,即,每辆车小于$3$分钟。这种被称为超快速充电(UFC)的技术引起了研究和工业界的极大兴趣。然而,UFC的大功率密度、脉冲和随机负载特性对现有的电力供应基础设施提出了前所未有的挑战。规划这些UFC电站的位置和电力容量对于防止有害影响至关重要,包括电网资产折旧,电网不稳定和电力质量恶化。在本文中,我们首先回顾传统充电站的规划方法,然后讨论展望UFC规划解决方案,通过绘制与可再生能源规划,它提出了类似的功率密度和随机特性的UFC的类比。虽然本文主要从电网的角度关注UFC规划,但其他城市方面,包括交通流量和最终用户行为,也将研究智能城市中可行的UFC集成。

英文摘要:

Plug-In Electric Vehicles (PEV) have become a key factor driving towards smart cities, which allow for higher energy efficiency and lower environmental impact across urban sectors. Industry vision for future PEV includes the ability to recharge a vehicle at a speed comparable to traditional gas refueling, i.e., less than $3$ minutes per vehicle. Such a technology, referred to as Ultra-Fast Charging (UFC), has drawn much interest from research and industry. The large power density, impulsive, and stochastic loading characteristics of UFC, however, pose unprecedented challenges to existing electricity supply infrastructure. Planning the locations and electric capacities of these UFC stations is critical to preventing detrimental impacts, including grid asset depreciation, grid instabilities, and deteriorated power quality. In this paper, we first review planning methods for conventional charging stations and then discuss outlooks for UFC planning solutions by drawing an analogy with renewable energy source planning, which presents similar power density and stochastic characteristics as UFC. While this paper mainly focuses on UFC planning from the power grid perspective, other urban aspects, including traffic flow and end-user behavior, are examined for feasible UFC integration within smart cities.
