Analysis of the Power System Damage Hazard from the Point of View of the Gas Supply System

The gas transmission network and the electricity transmission grid are subject to a number of threats and hazards that make them vulnerable and jeopardize the secure access to gas and electricity. Moreover, they are strongly interconnected and rely on the well-functioning of each other, and they are also interconnected with the information technology infrastructures. The target of this work is to perform a risk assessment of gas transmission networks. In the work is identified of key initiating events (failures of grid facilities) that may trigger cascading effects taking the grid to situations with the consequent loss of gas supply.
