Optimal PMU Placement on Network Branches for Intentional Islanding to Prevent Blackouts
Power grids, throughout the world, are operated as large interconnected networks to ensure reliability of supply in an economic way. The interconnected nature of power network makes it vulnerable and sometimes even a small disturbance in the grid may propagate and result in a blackout. Investigations into major blackouts of the decade in the world have identified inadequate monitoring of the dynamic phenomena occurring in the power grid as the primary reason behind blackouts. To overcome this drawback, it was recommended in various investigation reports that Phasor Measurement Units (PMUs) should be deployed throughout the grid.
