rates and the repair rates of the system components. Simulation models were
constructed for the various modules of the PMU and for its optical fiber
communication network, and the risk has been estimated. The proposed
methodology was used for obtaining the risk metrics for a practical power
grid of India, and it has been observed that by optimally placing the equip-
ment, the overall risk can be minimized.
