As power systems become increasingly stability constrained, the need for on-line dynamic security assessment (DSA) becomes more important. However, the technology to achieve on-line DSA at a reasonable cost for large power systems does not exist today. For example, a method is needed to examine and screen all likely contingencies to determine those that may lead to instability. A prototype offline program has been designed to help power system operators and operation planners set up cases and contingency conditions, check the input data for reasonableness, and screen the contingencies. Critical contingencies identified can then be analyzed using a time simulation program, such as EPRI`s Extended Transient-Midterm Stability Program (ETMSP), to determine if any contingency will lead to instability. This work is part of a larger EPRI effort to develop an on-line DSA program that is fully integrated with an energy management system. Such a system promises substantial economic savings and improved power system security.
