—Vulnerability assessment is a requirement of NERC's cybersecurity standards for electric power systems. The purpose is to study the impact of a cyber attack on supervisory control and data acquisition (SCADA) systems. Compliance of the requirement to meet the standard has become increasingly challenging as the system becomes more dispersed in wide areas.(More)
—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(More)

—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)
