Reducing greenhouse gas emissions have gained global interest over the last few decades. A key factor for reducing these emissions is shifting towards renewable energy resources (RES) in electricity generation and low or zero-emission vehicles in transportation. Electrification of the transportation sector is currently the most viable option for reducing transportation emissions and thus the production of plug-in electric vehicles (PEVs) is predicted to rise dramatically in the next few decades. However, integrating large levels of RES and PEVs charging stations into existing distribution system structure creates major voltage regulation challenges due to reverse power flow, power generation/consumption intermittency, and interference with the operation of utility voltage regulation devices. Despite these challenges, other considerations show promise. Battery Energy storage systems (BESS) can be a critical component of grid stability and resiliency. The grid integration of energy storage technologies would reduce the intermittency of RES and also prevent wastage of excess renewable energy feeding into the grid at times when production is at a peak, but demand is low by effectively storing this energy. In addition, integrating BESS into existing grids could enable confident deployment of PEVs by ensuring a stable and consistent supply of the electricity vital to charge their batteries. Toward that end, this project aims to (I) incorporate BESS in the voltage regulation studies of power distribution systems with high penetration of RES and PEVs , and (II) develop a distributed voltage regulation scheme to provide appropriate coordination among the control units of BESS, RES, PEVs and utility voltage regulation devices. The proposed distributed control will help the distribution utilities to mitigate the voltage regulation challenges and thus facilitate seamless integration for high penetration of RES and PEVs into the current grid infrastructure.

过去几十年来，减少温室气体排放引起了全球的关注。减少这些排放的一个关键因素是转向发电中的可再生能源 (RES) 以及运输中的低排放或零排放车辆。交通运输部门的电气化是目前减少交通排放最可行的选择，因此插电式电动汽车（PEV）的产量预计在未来几十年内将大幅增长。然而，将大量可再生能源和电动汽车充电站集成到现有的配电系统结构中，由于反向潮流、发电/用电间歇性以及对公用电压调节装置运行的干扰，带来了重大的电压调节挑战。尽管存在这些挑战，但其他考虑因素也显示出希望。电池储能系统 (BESS) 是电网稳定性和弹性的关键组成部分。储能技术的电网整合将减少可再生能源的间歇性，并通过有效存储这些能源，防止在生产高峰但需求较低时输入电网的多余可再生能源的浪费。此外，将 BESS 集成到现有电网中可以确保稳定、持续地供应对电池充电至关重要的电力，从而能够自信地部署 PEV。为此，该项目旨在（I）将BESS纳入RES和PEV高渗透率的配电系统的电压调节研究中，以及（II）开发分布式电压调节方案，以在BESS的控制单元之间提供适当的协调、RES、PEV 和公用电压调节装置。拟议的分布式控制将帮助配电公司缓解电压调节挑战，从而促进可再生能源和电动汽车在当前电网基础设施中的高度渗透的无缝集成。
