A method for the on-line implementation of dynamic security assessment has been pursued for a long time. Now the key problem lies in how to reduce the computation burden. This paper presents a method abased on the concept of automatic contingency selection to speed up dynamic security assessment. Six kinds of performance indices are developed to quantitatively evaluate the severity of contingencies. Combining the proposed automatic contingency selection algorithm with a fast integration procedure, a new framework for dynamic security assessment is introduced. Simulation results show the rapidity and robustness of the proposed procedure.
