Control and Communication Techniques for the Smart Grid: An Energy Efficiency Perspective

Abstract

Energy is a major driver of developments in human society. Naturally, the energy efficiency of power grids qualifies as an important topic. Half a century old, the world's power grids are due for a major overhaul. The envisioned energy-efficient, environment-friendly, distributed-generation-friendly, demand-response-friendly, self-healing power grid is called the smart grid. This article is intended as a primer on the control and communication techniques that form the basis of several smart grid subsystems, namely distributed generation, wide-area monitoring, distribution automation, and substation automation. The theme of this article is to show how these techniques contribute to the efficiency of the generation, transmission, and distribution segments of a grid. Potential research challenges and opportunities are indicated. To complement our technical discussion, noteworthy smart grid developments in Australia (one of the world's top investors in smart grids) are highlighted.

Two Novel Approaches of NTSMC and ANTSMC Synchronization for Smart Grid Chaotic Systems

“…The numerical solution of Eq. (17) shows that the variables converge to zero in the finite time, T r , and the upper bound of this time is as below [23].…”

“…In [24], a multi-agent based protection framework has been proposed to improve the transient stability of smart grids. In [17], a comprehensive review on the control and communication techniques has been done for the smart grids where the energy efficiency of the smart grids has been focused. In (X.…”

Control and communication of renewable energy based smart grid: an overview

“…The involvement of RESs makes it more difficult due to the uncertainty involved with it. Therefore, the new control strategies with new optimization tools such as adaptive dynamic programming, stochastic programming, heuristic programming and evolutionary programming are suggested by researchers as a solution to this problem [17]. The use of RESs as distributed generation burdens the Distributed Managements System (DMS) with some activities of Energy Management System (EMS).…”

Avaliação da Confiabilidade de uma Rede Wi-Sun com Topologia Linear para Aplicações de Cidades Inteligentes

“…Tais questões levaram o IEEE a fazer emendas no padrão com o objetivo de superar essas limitações, o que originou as emendas IEEE 802. 15.4g e IEEE 802.15.4e [6], [7].…”

“…Essa técnica é geralmente utilizada quando as distâncias físicas a serem cobertas pelos nós são demasiado grandes e há a impossibilidade de comunicações diretas. Um exemplo de uso é no monitoramento de de linhas de transmissão de energia elétrica [15].…”
