Abstract
The term “Smart Grid” has been coined and used for several years to describe the efforts of the current power grid modernization effort. This effort plans to introduce self-healing, energy efficiency, reliability, and security using two-way digital communications and control technology, along with a
Highlights
The smart grid can be described as a physical and cyber upgrade of the current power grid which will allow it to diagnose and heal itself, to dynamically integrate renewable energy from various sources to relieve dependency on centralized generation, and to provide the customer more control over electricity demand and cost [1]
Once measurements are sent to the appropriate entities and verified, the results can be viewed on an Energy Management System (EMS) which may provide an interface to the control capabilities in order to make appropriate modifications to grid operations
Since the natures of the systems in a smart grid environment are complex and critical to the current state of technology and human well-being, they require quality and sufficient security mechanisms and solutions. This must equate to a holistic approach where all threats and vulnerabilities are considered, including future hazards
Summary
The smart grid can be described as a physical and cyber upgrade of the current power grid which will allow it to diagnose and heal itself, to dynamically integrate renewable energy from various sources to relieve dependency on centralized generation, and to provide the customer more control over electricity demand and cost [1]. To convey a context for understanding this necessity, this paper will give a review of past attacks and vulnerabilities of the smart grid and inspect and highlight some areas for additional research which may reveal other weaknesses Recent work in this area includes [3], which utilized a custom cyber-security testbed architecture in order to detail attack and mitigation scenarios within that simulated microgrid environment. The authors in [18] supply the reader with some attack categories, and some security fundamentals in the areas of access control, authentication, and privacy along with intrusion detection are discussed Recent work in this area has failed to give detailed accounts of techniques which exploit these issues and vulnerabilities in the smart grid and its technologies.
