Disruption of electric power operations can be catastrophic on national security and the economy. Due to the complexity of widely dispersed assets and the interdependences among computer, communication, and power infrastructures, the requirement to meet security and quality compliance on operations is a challenging issue. In recent years, the North American(More)
Disruption of electric power operations can be catastrophic on the national security and economy. Due to the complexity of widely dispersed assets and the interdependency between computer, communication, and power systems, the requirement to meet security and quality compliance on the operations is a challenging issue.

This paper is concerned about strategic deployment of feeder remote terminal unit (FRTU) in primary network by considering cybersecurity of distribution secondary network. First, detection of historical anomaly load profile in secondary network is assumed to be observable. These irregularities of historical energy usages can be determined from consumer(More)
In this paper, a methodology is proposed for the evaluation of the impact of cyber attacks on the power grid. This is a systematical approach to evaluate the vulnerabilities of SCADA system at three levels, i.e., <i>system, scenario</i>, and <i>access points</i>. The impact of potential intrusion is evaluated based on the power flow solution. The(More)
Advanced metering infrastructure (AMI) deployment has been widely promoted in recent years to improve the accuracy of billing information as well as to facilitate implementation of demand response. Information integrity and availability of the devices is crucial to the billing information that should reflect accurately on how much the household energy is(More)
The transformation of substation operations from mechanical relays to microprocessor-based intelligent devices has enhanced the communication framework for power system protection. In recent years, the implementation of Internet protocol (IP)-based communication between a substation network and control center has raised its criticality with regard to(More)
