Probabilistic Reliability Evaluation of Korea Power System in Operation Mode

Reliable operation of power system is fundamental to the on-going industry reform. This paper presents the result of marginal power flow evaluation performed on Korean power system using two commercial software packages: Physical and Operational Margins (POM V. 2.2) and probabilistic reliability assessment (PRA V. 3.1), respectively. The case study of Korea power system for year 2006 data shows that these packages are effective in identifying possible weak points and root causes for likely reliability problems. The potential for these software packages is being explored further for assisting system operators with managing Korea power system under real-life setting in the near future.
