Vulnerability analysis and PMUs as next generation protection system in Smart Grid

Vulnerability analysis in modern power systems is essential to mitigate cascading failures. This assumes prominence in the wake of permeation of information and communication technologies in the operation of power systems. Most research works have focused on vulnerability analysis of either general interdependent infrastructure systems or power systems. As a part of this work, it will be of interest to identify the existing approaches in vulnerability analysis in power systems as well as ICT infrastructures. Phaser Measurement Units (PMUs) are typically used in Wide Area Measurement (WAM) systems to predict and prevent cascading failures. The role of PMUs in preventing cascading failures because of interaction between ICT and the power grid in future Smart Grid is reviewed.
