Abstract

A dynamic security assessment (DSA) function implemented in an energy management system (EMS) environment improves the reliability, identifies additional energy transaction potential and results in better use of engineering resources. An online DSA function monitors the state of the power system periodically, on demand, and upon occurrence of significant changes in the state of the power system, and ensures power system security against the occurrence of predefined specific or generic dynamic contingencies. The main features of the function include: contingency screening; time simulation for accurate transient stability assessment of contingencies; calculation of power transfer limits; and concurrent processing of contingencies.
