 ABSTRACT

This document provides information for a report to congress on Smart Grid security as required by Section 1309 of Title XIII of the Energy Independence and Security Act of 2007. The security of any future Smart Grid is dependent on successfully addressing the cyber security issues associated with the nation’s current power grid. Smart Grid will utilize numerous legacy systems and technologies that are currently installed.Therefore, known vulnerabilities in these legacy systems must be remediated and associated risks mitigated in order to increase the security and success of the Smart Grid. The implementation of Smart Grid will include the deployment of many new technologies and multiple communication infrastructures. This report describes the main technologies that support Smart Grid and summarizes the status of implementation into the existing U.S. electrical infrastruc The current U.S. electrical power grid is an out-of-date infrastructure, and the Smart Grid is an upgrade that will add many new functionalities to meet customers' new power requirements Updating a system as complex as the electrical power grid has the potential of introducing neW security vulnerabilities into the system. This document presents a review of the work related to Smart Grid cyber security. The work reviewed is separated into _ve categories that make up different components of the Smart Grid: Process Control System (PCS) Security, Smart Meter Security, Power System State Estimation Security, Smart Grid Communication Protocol Security and Smart Grid Simulation for Security Analysis. The Smart Grid is a largecomplex system, and it still requires a lot of cyber security design work.

INTRODUCTION
CHAPTER 1

The current U.S. electrical power grid is an out-of-date infrastructure. It has met our needs inthe past; however, as oursociety advances technologically so do the expectations we have of ou electrical power delivery system.

The Smart Grid is a movement to bring the electrical power grid up to date so it can meet the current and future requirements of its customers. Updating our electrical power grid could introduce new security vulnerabilities into the system. This documentpresents a review of the work related to Smart Grid cyber security . What is the Smart Grid? The Smart Grid is an electrical power infrastructure that makes intelligent decisions about the state of the electrical power system to maintain astable environment . The easiest way to de_ne the Smart Grid is by its characteristics. The Smart Grid is an upgradeto the current electrical power system, so it has all of the functionality of our current power system plus several new

functionalities

Self-healing

Motivates and includes the consumer

Resists attack

Increases power quality

Accommodates all generation and storage options

Enables electrical markets

Optimizes assets and operates efficiently.
