Transmission system reliability evaluation of KEPCO system in face of deregulation

The reliability evaluation of a transmission system is being realized to play an important role in the electric power systems under the situation of deregulation, because the electricity transmission system will be planned, operated and maintained by an independent transmission administrator in the new electric industry structure. The new concept of the CMELDC (CoMposite power system Effective Load Duration Curves) has been developed to evaluate the nodal reliabilities, to simulate the nodal probabilistic production cost and to assess outage cost on the composite power systems by the authors in recently. Reliability of the transmission system can be also evaluated with the CMELDC. The methodology of reliability evaluation of the transmission system is based on the concept that the reliability level of a transmission system is equal to the difference in the reliability levels of the composite power systems(HLII) and generation system(HLI). In this study, the transmission system reliability of the KEPCO(Korea Electric Power Corporation) system was evaluated under a deregulated electricity market.
