거시적인 접근방법을 통한 공급지장비 추정에 관한 연구

초록

Electric power utilities are facing increasing uncertainties regarding the economic, political, societal,environmental constraints under they operate and plan their future systems. The utilities have to integrate consumers'interruption cost representing reliability worth of electricity into the process of determining the optimum investment level. In order to do so, the estimated outage cost must be included into quantitative index corresponding to system capital and operation investment cost to establish an optimal expansion plan. This paper is a study on the outage cost assessment by using macro approach for calculating IEAR(Interrupted Energy Assessment Rates) and the TRELSS(Transmission Reliability Evaluation for Large-Scale Systems) program was used to calculate EENS(Expected Energy Not Served).
