The reliability theory used in the design of complex systems including electric grids assumes random component failures and is thus unsuited to analyzing security risks due to attackers that intentionally damage several components of the system. In this paper, a security risk analysis methodology is proposed consisting of vulnerability analysis and impact analysis. Vulnerability analysis is a method...
Electric grid automation is designed so that any single component failure can be isolated, and that supply can be quickly restored to the remainder of the network. However, environmental hazards such as flooding may cause the failure of several components in the grid, resulting in an unforeseen loss of power. Automation may be helpful in limiting the consequences of environmental hazards, but no methods...
