本文重点介绍了建设决策者所称的“智能电网”的努力，包括1）改善高压输电网络设施的远程监控和自动远程控制; 2）改善本地配电网络的远程监控、双向通信和自动远程控制;以及3）在客户楼宇安装“智能”计量装置及相关的通讯设施，使客户可接收实时价格信息，以及/或利用机会与零售供应商签订合同，远程管理消费者的电力需求，以应对批发价格和网络拥塞。我研究的机会，挑战和不确定性与“智能电网”技术的投资。我讨论了一些基本的电力供应和需求，定价和物理网络属性，这些属性对于理解与智能电网技术扩展部署相关的机遇和挑战至关重要。然后，我将介绍与这些技术在高压输电、本地配电和终端计量层面的部署相关的问题。
This paper focuses on efforts to build what policymakers call the "smart grid," involving 1) improved remote monitoring and automatic and remote control of facilities in high-voltage electricity transmission networks; 2) improved remote monitoring, two-way communications, and automatic and remote control of local distribution networks; and 3) installation of "smart" metering and associated communications capabilities on customer premises so that customers can receive real-time price information and/or take advantage of opportunities to contract with their retail supplier to manage the consumer's electricity demands remotely in response to wholesale prices and network congestion. I examine the opportunities, challenges, and uncertainties associated with investments in "smart grid" technologies. I discuss some basic electricity supply and demand, pricing, and physical network attributes that are critical for understanding the opportunities and challenges associated with expanding deployment of smart grid technologies. Then I cover issues associated with the deployment of these technologies at the high voltage transmission, local distribution, and end-use metering levels.
