Abstract

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.

放松管制下韩国电力系统输电系统可靠性评估

在新的电力产业结构下，输电系统将由独立的输电管理人员规划、运营和维护，输电系统可靠性评估在电力系统中发挥着重要的作用。近年来，作者提出了复合电力系统有效负荷持续时间曲线(CMELDC)的新概念，用于评估复合电力系统的节点可靠性、模拟节点概率生产成本和评估停电成本。传输系统的可靠性也可以用CMELDC进行评估。输电系统的可靠性评价方法是基于输电系统的可靠性水平等于复合电力系统(HLII)和发电系统(HLI)的可靠性水平之差的概念。在本研究中，韩国电力公司(韩国电力公司)系统的传输系统可靠性评估在放松管制的电力市场。
