Advances in electrical vehicles (EV) technology are resulting in an increased usage of EV and a large scale penetration of the Canadian and Quebec markets. The usage of EVs is expected to witness massive growth in the near future with the increased awareness towards green energy use and the need for less dependency on fossil fuel. Among the outcomes of EV use, the incremental deployment of charging stations (especially level 2 charges) presents a challenge to the power distribution network. As anticipated, most of the EVs will be charged at home to avoid long waiting times at public charging stations (CS), and utilize their idle time in EV charging. This approach is facilitated by the declining prices of level 2 charges which reduce the EV charging time. Thus, we will witness a significant change in the residential load profile and an augmented demand at various times of the day. Hydro Quebec, the sole electricity provider in Quebec, will have to prepare for the consequences of this notable increase in EVs use and upcoming deployments of level 2 chargers.****To assess the consequences of this enormous increase in the number of EVs on the power sector, and to avoid these unavoidable consequences, an extensive analysis is required to have a better understanding of the impact of this change first, and elaborate suitable strategies after. In this respect, we will study the EV market growth and the charging behavior of EVs. Our preliminary observations indicate a paradigm shift of transportation sector to EV; within a few years, level 2 charges along with future more efficient and fast charges will constitute the major charging stations even at the level of residential premises. As a ramification, a drastic change in residential load is anticipated. To accommodate to this change in load, Hydro Quebec may need to introduce dynamic pricing policy, or expand their power distribution network or both. As this energy demand is expected to be increased gradually, a gradual solution might be more effective. Insights into the dynamics of this problem, and advanced solutions will be possible through a simulation that mimics the variations in EV deployment, charging behavior, and load alterations. We envision developing a simulator that allows to experiment with all variable aspects of the problem at hand, and consequently portray efficient and suitable solutions suitable on the short term, and long term as well.****

电动汽车(EV)技术的进步导致电动汽车的使用量增加，并大规模渗透到加拿大和魁北克市场。随着人们对绿色能源使用意识的提高和减少对化石燃料的依赖，电动汽车的使用预计在不久的将来将出现大规模增长。在电动汽车使用的成果中，逐步部署充电站(特别是二级充电)对配电网提出了挑战。正如预期的那样，大多数电动汽车将在家中充电，以避免在公共充电站(CS)长时间等待，并利用其空闲时间进行电动汽车充电。第二级收费的价格下降，缩短了电动汽车的充电时间，促进了这一方法的实施。因此，我们将在一天中的不同时间看到住宅负荷分布的显著变化和需求的增加。魁北克水电公司是魁北克唯一的电力供应商，将不得不为电动汽车使用量的显著增加和即将部署的二级充电器的后果做好准备。*为了评估电动汽车数量的大幅增加对电力部门的影响，并避免这些不可避免的后果，需要进行广泛的分析，首先更好地了解这一变化的影响，然后制定适当的战略。在这方面，我们将研究电动汽车市场的增长和电动汽车的充电行为。我们的初步观察表明，交通部门将转向电动汽车；在几年内，二级充电以及未来更高效、更快速的充电将构成主要的充电站，甚至在住宅层面也是如此。作为一个分支，预计住宅负荷将发生剧烈变化。为了适应这种负荷变化，魁北克水电可能需要引入动态定价政策，或者扩大他们的配电网络，或者两者兼而有之。由于这种能源需求预计将逐步增加，循序渐进的解决方案可能更有效。通过模拟电动汽车部署、充电行为和负载变化的变化，可以深入了解这个问题的动态，并提供先进的解决方案。我们设想开发一种模拟器，允许对手头问题的所有不同方面进行实验，从而描绘出适合短期和长期的有效和合适的解决方案。
