Abstract :
In this paper, we propose the reliability evaluation method of power distribution systems considering the momentary interruptions. The results of research are concentrated on two parts. One is the reliability evaluation method of power distribution system considering the momentary interruptions and the other is the reliability cost evaluation that unifies the sustained and momentary interruption costs. These proposed evaluation methodologies are divided into the analytic and probabilistic method. Time sequential Monte Carlo method is used for the probabilistic methodology. The proposed methods are tested using the modified RBTS (Roy Billinton test system) form and historical reliability data of KEPCO (Korea Electric Power Corporation) system. Through the case studies, it is verified that the proposed reliability cost evaluation can be used to evaluate the actual reliability.
