簡介

近年來,美國和歐盟的電力需求一直持平或下降,這威脅了隨著需求增加而增加收入的傳統商業公用事業模式。但是,電動汽車的採用以及它們使用的功率的預計增加代表了電力公司可以出售給消費者的功率數量的急劇增加,這支持了不斷變化的基本面。但是,間歇性的充電時間和地理集群會加劇高峰需求問題並威脅變壓器。

不斷發展的電動汽車市場,充電基礎設施和充電時間預計將對公用事業負荷的幾何形狀產生重大影響。公用事業公司需要考慮各種戰略,例如價格信號和車輛-電網整合,以確定如何納入投資戰略和需求的逐步變化。這些工具可幫助電力公司和監管機構微調EV充電行為,以最大程度地降低對電網的破壞性影響,降低消費者成本並減少碳排放。

本報告調查了對電網有利的電動汽車負荷曲線的優化,成熟的電動汽車和充電市場,電動汽車電網的影響,需求響應,能源存儲和管理從理論到實用的過渡。它提供信息,例如潛在公用事業的好處,例如收費。

Electricity demand in the US and European Union has been flat or down for several years, threatening the traditional business utility model of greater demand driving higher revenue. However, projected growth in EV adoption and the electricity that EVs use represent a dramatic increase in the amount of power that utilities will likely sell to consumers, buttressing shaky fundamentals. However, intermittent charge times and geographic clustering could exacerbate peak demand issues and threaten transformers.

The evolving EV market, charging infrastructure, and charge times are expected to have a big impact on utility load shapes. These trends are magnified by increases in solar generation, which leads to a greater discrepancy between low midday demand and peak demand when people return home from work. As utilities determine investment strategies and how to incorporate a step-change in demand, they will need consider a range of strategies including price signals and vehicle-to-grid integration. These tools can help utilities and regulators nudge EV charging behavior to minimize disruptive grid impacts, lower consumer costs, and reduce carbon emissions.

This Guidehouse Insights report explores the maturing EV and charging markets, the move from EV grid impacts from theoretical to practical, and potential utility benefits, including demand response, energy storage, and managed charging. The report also explores this question: how are EVs and renewables exacerbating load shape peaks and troughs? Recommendations for utilities and other stakeholders are provided along with instruments in utility and regulator toolbelts that could help shift EV load.

KEY QUESTIONS ADDRESSED:

  • What are utility risks and opportunities associated with increased EV demand?
  • Will increased demand from EVs cause rolling brownouts?
  • How could price signals and vehicle-grid-integration affect EV impacts on utility load shapes?
  • What are the interrelationships between EVs and solar generation on utility load shapes?
  • What are the hourly grid impacts of different types of charging (e.g., workplace and single unit dwelling)?

WHO NEEDS THIS REPORT:

  • Utility executives
  • Public utilities commission regulators
  • Electricity demand response program implementers
  • Environmental non-profits
  • Auto manufacturers
  • Charging infrastructure OEMs
  • Investor community
