Distribution factors, which are linear approximations of the sensitivities of the system variables for changes in the power injections or any events in the system, play an important role in the security analysis and market applications. Cascading faults, which are triggered by the overloading of lines due to a fault has been the major issue deteriorating the reliability of the power system thereby requiring measures to revert the power flow on overloaded lines. This paper proposes an algorithm, by utilizing the formulation of PTDFs and LODFs, to calculate the generation shifts so that the power flow on the transmission lines that violate security limits due to single and multiple-line outage events are adjusted to its security limits. This methodology is being tested on the IEEE New England 10-generator 39-bus system for effectiveness.
