NeTS: Small: Smart Grid Wireless Networks: Capacity and Achievability

智能电网是通过将具有双向通信的传感、测量和控制设备应用于电网的生产、传输、分配和消费部分来实现的，这些设备将关于电网状况的信息传达给系统用户、操作员和自动化设备，从而使其能够动态地响应电网状况的变化。智能电网最终是一种无线混合网络，并对其容量和可实现性进行了研究。采用信息论的多址接入方法，研究了智能电网与智能家居、正方形电网与智能电网、基站与天线阵列三个方面的问题。通过分析由多模式传感器/仪表组成的智能电网的速率，研究了容量的可达成性。不同的传感器模式可能是独立的，也可能是独立的，并得出一些初步的基本结果，随后将其应用于智能电网无线网络。美国能源部进行的一项研究得出结论，美国电网内部现代化的智能电网功能将在未来20年节省460亿至1170亿美元。受益最大的将是智能计量硬件的销售商和软件制造商，这些软件用于传输和组织仪表收集的大量数据。本项目的能力研究为智能电网传输海量数据提供了上限，可实现性研究为组织电表采集的海量数据提供了一种有效的方法。

A smart grid is made possible by applying sensing, measurement and control devices with two-way communications to electricity production, transmission, distribution, and consumption parts of the power grid that communicate information about grid condition to system users, operators and automated devices, making it possible to dynamically respond to changes in grid condition. A smart grid is eventually a wireless hybrid network, and its capacity and achievability are studied. An information theoretic approach for multiple access channels is applied to increase the throughput capacity, and three tasks are studied: 1) smart grid versus smart home, 2) square network versus smart grid network, and 3) base stations with antenna array. The achievability of the capacity is studied via analyzing the rate of smart grid which consists of multimodal sensors/meters. Different sensor modalities may be independent or dependent, and some preliminary fundamental results are derived and are subsequently applied to smart grid wireless network.One study conducted by the US Department of Energy concludes that internal modernization of US grids with smart grid capabilities would save between 46 and 117 billion dollars over the next 20 years. With the segments set to benefit the most will be smart metering hardware sellers and makers of software used to transmit and organize the massive amount of data collected by meters. The capacity study performed in this project provides the upper bound for the smart grid to transmit the massive amount of data, and the achievability study provides an efficient way to organize the massive amount of data collected by meters.
