Abstract :
Cascading failure in power networks is studied considering power flow limit on each line. The concept of correlation of lines in power grids is proposed. It explains the interaction between lines during cascading failure. An algorithm which calculates the correlated lines in a cascading failure is developed based on the DC power flow model. Computation is carried out on an IEEE 14-bus system. The results verify the significance of the concept and the algorithm.
