분산전원의 최적 연계 위치 탐색을 위한 배전선로의 감도 해석 연구

Abstract

With the recent increase in the number of DERs, there is a high possibility that voltage quality problems will occur. In order to solve this problem, it is important to determine the optimal location of DERs. Therefore, in this paper, in order to develop an optimization algorithm to determine the optimal placement of DERs, the first step is to perform a sensitivity analysis on the distribution line. At this time, static voltage stability, voltage-active power characteristics and voltage violation rate of distribution lines are reviewed using the actual system data and the OpenDSS module based on Matlab.
