This paper aims to identify and analyze the initial contingencies ordisturbances that could lead to the worst-case cascading failures of powergrids. An optimal control approach is proposed to determine the most disruptivedisturbances on the branch of power transmission system by regarding thedisturbances as the control inputs. Moreover, protective actions such as loadshedding and generation dispatch are taken into account in a convexoptimization framework to prevent the cascading outages of power grids. Intheory, the necessary conditions for identifying the most disruptivedisturbances are obtained by solving an integrated system of algebraicequations. Finally, numerical simulations are carried out to validate theproposed approach on the IEEE RTS 24 Bus System.
