AN EFFICIENT UNIFIED METHODOLOGY FOR STEADY-STATE AND DYNAMIC SECURITY ASSESSMENT OF POWER-SYSTEMS

An approach to forming an efficient unified methodology and computer program for power system security analysis for the purposes of operational planning is presented. The proposed methodology, taking into consideration the usual aspects of steady-state security, also encompasses the aspects of dynamic security, so that either one or both types can be treated. Furthermore, an important characteristic is the developed efficient unified solution techniques of the system models, which secure the necessary speed and economy of simulation, as well as the corresponding unification of the computer program, a characteristic indispensible for realizing the application software support of energy management systems of modern electric power systems.
