Vulnerability Assessment in Power Systems: A Review and Representing Novel Perspectives

Due to environmental impacts and high cost of transmission network expansion, power systems are loaded closer to their limits, which increases their vulnerability and possible blackouts. In this paper, the recent literature in the steady-state vulnerability assessment (SSVA) and dynamic vulnerability assessment (DVA) are classified and reviewed. After finding the research gaps arising from the current literature review, several systematic ideas are presented in terms of designing a modular framework with a generalized index to determine the vulnerable areas of system, integrated T&D system vulnerability assessment, and vulnerability of PMUs to cyber-attacks.
