A Basic Study of Applying the Energy Function Using Time-domain Transient Stability Program

시간영역 과도안정도 프로그램을 이용한 에너지 함수 적용 기초 연구

This paper presents new contingency screen and ranking method using the time-domain simulation program and energy function. Since the suggested method is very simple and has fast computation time to calculate energy margin and list the contingency according to the its severity, it can be used in connection with the on-line TSA which has accurate binary search algorithm in parallel or distributed computing environment. The suggested method has been tested by appling to 3-machine and 9-bus system, and its effectiveness has been verified.
