Cyber Security in Smart Grid

Abstract

The smart grid harnesses the power of information technology to provide energy intelligently using two-way communication and wisely meets environmental requirements by facilitating the integration of green technologies. The intelligent network is a system based on communication and information technology in the generation, delivery and consumption of energy. It uses the bi-directional flow of information to create an automated and widely distributed system that has new features such as real-time control, operational efficiency, network resilience and better integration of renewable technology that will reduce the carbon footprint. Any interruptions in power generation could disrupt the stability of the smart grid and could potentially have major socio-economic impacts. These survey documents provide various classifications of smart grid attacks, most of which are based on confidentiality, integrity or availability. We examine cyber security goals in the smart network and describe a new classification of cyber attacks based on a method used by hackers or penetration testers. This document provides an overview of the current state and future directions of cyber security of the intelligent network. The main contribution of this review is to provide a complete overview of resilience in power systems: definitions, frameworks, metrics and practices.
