  • This paper presents an Unified Index which can evaluate a performance of a distribution system based on value-based methodology. Reliability cost and voltage sags cost are calculated for each load point using Reliability Sector Customer Damage Function(SCDF). Aging cost is calculated for each load point using Aging SCDF. Power loss cost and operation cost are calculated for the system. By summation of each cost of load point and system, power quality cost can be obtained. Finally, this paper developed an unified index which can show the performance of a distribution system. Presented method has been applied to a real system, the usefulness of the method has been verified.

  • 본 연구에서는 배전시스템 안정성의 요소라 할 수 있는 고조파, 전압변동, Sag/Swell, 신뢰도의 측면에서 배전시스템을 전력품질 측면에서 안정성을 종합적으로 평가하는 방법을 개발하였다. 시스템이 전력품질의 측면에서 얼마나 안정적인가를 정량적으로 평가하기 위해서 AHP(Analytic Hierarchy Process)를 사용하여 종합 전력품질 통합지수를 산정하는 방법을 제안하였다. 또한 몬테카를로 시뮬레이션을 수행함으로서 사고를 고려한 배전계통의 안정성을 평가하였다.

  • This paper presents a power quality assessment model based on the Analytic hierarchy process. This model can assess unified power quality index which provide an overall performance of the distribution system. To obtain the unified power quality index, we propose the use of the AHP model which has three states: [Ideal]-[Actual]-[Worst]. The proposed method is especially useful and effective for planning. We have applied the proposed method to an actual relatively large system, and verified the usefulness.
