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电力生产、传输、分配和消耗部分，将有关电网状况的信息传递给系统用户、操作员和自动化设备，从而可以动态地响应电网状况的变化。智能电网最终是一个无线混合网络，其容量和可扩展性进行了研究。应用多址信道的信息论方法来增加吞吐量，并研究了三个任务：1）智能电网与智能家居，2）方形网络与智能电网网络，以及3）具有天线阵列的基站。通过分析由多模态传感器/仪表组成的智能电网的速率，研究了容量的可扩展性。不同的传感器模态可以是独立的或依赖的，并得出一些初步的基本结果，并随后应用于智能电网无线网络，由美国能源部进行的一项研究得出结论，美国电网的内部现代化与智能电网的能力将节省46和117亿美元之间在未来20年。随着细分市场的设置，受益最多的将是智能计量硬件销售商和软件制造商，用于传输和组织由仪表收集的大量数据。该项目中进行的容量研究为智能电网传输大量数据提供了上限，可扩展性研究为组织电表收集的大量数据提供了有效方法。

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.
