Smart Grid Communication: Recent Trends and Challenges

Abstract

AbstractThe complexity of power distribution network is increasing day by day with rapid increase in power demand. For monitoring and control of this complex power network, application of smart grid technologies is essential. These technologies can also improve the overall system reliability and system security. A two-way communication network is the main requirement for optimal operation of a smart grid. In modern grid, different sensors and Intelligent Electronic Devices (IED) are installed at various locations. All these devices share different information related to the state of the network like voltage, current, power flow etc., through a two-way communication channel. Maximum utilization of the network communication system resources like sensors, IEDs and smart meters can ensure most economical operation of the grid. However, this communication channel can be subjected to various challenges like cyber attacks, interference and data loss which can be a major hurdle in deployment gird automation strategies. In this chapter, the evolution of communication technology from wired network to wireless network along with architecture of the smart grid is discussed; various standards and protocols related to smart grid communication are presented. The authors also explained different challenges and their possible solutions for two-way communication infrastructure of smart grid.KeywordsSmart gridWireless communicationSmart gird standardsCyber-securityCompressive sensing
