Over the last few years, there have been an increase in the environmental concerns over greenhouse emission and its effect on global warming. Much of the emission is attributed to vehicles that use fossil fuel in their internal combustion engines. These concerns have led many environmental activists, empowered by various provincial and federal incentives, to advocate for Plug-in Electrical Vehicles (EVs). These vehicles can use electricity stored in battery packs instead of fuel, and can be recharged from the electrical grid. These vehicles have lower cost for operation, with minimal or no air pollution and greenhouse gas emissions [1,2]. In addition, using EV can also improve the efficiency, stability, and reliability of the grid [3]. Veridian Connections is a local distribution utility company serving more than 117,000 residential and business customers in the Greater Toronto Area (GTA). Veridian has been a long-term advocate of EV with a number of charging stations deployed in its service area in a pilot program. Based on the initial numbers from these charging stations, Veridian is becoming more aware and concerned about the impact EV will have on its distribution network: the additional demand on electricity to charge EVs, added to the initial load from homes and businesses, can result in an upsurge in the temperature of electric transformers in the grid, thereby reducing their lifetime. These results are, however, reliant on charging profile, EV penetration rate, driving pattern, and time of charging of vehicles [4]. Although with the current adoption rate of EV, the impact is still minimum on the current grid, the long term planning and deployment approaches for local distribution companies, including Veridian, requires research and analysis using various possible scenarios. In order to address this problem, Veridian reached out to Dr. Pazzi for help developping an analytical simulation framework to allow Veridian study the potential impact of EV loads on Veridian's distribution network. Dr. Pazzi is an expert in network simulation, with an extensive knowledge of mobility models and performance evaluation of vehicular networks.

在过去几年中，人们越来越关注温室气体排放及其对全球变暖的影响。大部分的排放是由于车辆使用化石燃料的内燃机。这些担忧导致许多环保活动家在各种省级和联邦激励措施的支持下，倡导插电式电动汽车（EV）。这些车辆可以使用存储在电池组中的电力而不是燃料，并且可以从电网充电。这些车辆的运营成本较低，空气污染和温室气体排放量最小或没有[1，2]。此外，使用EV还可以提高电网的效率，稳定性和可靠性[3]。 Veridian Connections是一家本地配电公用事业公司，为大多伦多地区（GTA）的117，000多名住宅和商业客户提供服务。Veridian一直是电动汽车的长期倡导者，在其服务区部署了许多充电站。根据这些充电站的初始数据，Veridian越来越意识到并关注电动汽车对其配电网络的影响：为电动汽车充电的额外电力需求，加上家庭和企业的初始负载，可能导致电网中变压器的温度升高，从而缩短其使用寿命。然而，这些结果依赖于充电曲线、EV渗透率、驾驶模式和车辆充电时间[4]。虽然以目前电动汽车的普及率， 当前的电网，包括Veridian在内的本地配电公司的长期规划和部署方法，需要使用各种可能的方案进行研究和分析。为了解决这个问题，Veridian联系了Pazzi博士，请他帮助开发一个分析模拟框架，以使Veridian能够研究电动汽车负载对Veridian配电网络的潜在影响。Pazzi博士是网络仿真方面的专家，在移动模型和车载网络性能评估方面拥有丰富的知识。
