Probabilistic Reliability Evaluation of Power System using TRELSS VI - Case Study on Transmission Line Planning -

TRELSS를 이용한 전력계통의 확률론적 신뢰도 평가 VI - 송전망 확충계획시 응용에 관한 사례연구 -

This paper suggests the power system reliability evaluation fur transmission lines planning in composite power systems. In recent the importance and necessity of some studies on reliability evaluation of grid comes from the recent black-out accidents occurred in the world. Since probabilistic criterion can reflect recognize the probabilistic nature of system components, the application of probabilistic criterion has received a lot of attention. This paper introduces features and operation modes of the Transmission Reliability Evaluation fur Large-Scale Systems(TRELSS) Version 6.2, a program made in EPRI, for assessing reliability indices of composite power system. The characteristics of the TRELSS program are illustrated by the case studies using the KEPCO system.
