Probabilistic Reliability Evaluation of Korea Power System in Planning 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 for planning mode. It uses two commercial software packages: physical and operational margins (POM V. 2.2) and probabilistic reliability assessment (PRA V. 3.1), respectively. The case studies of Korea power system for year 2007 - 2012 data show that these packages are effective in identifying possible weak points and root causes for likely reliability problems for long term planning. The potential for these software packages is being explored further for assisting system operators and planners with managing and planning Korea power system under real-life setting in the near future.
