An optimization model based interval power flow analysis method considering the tracking characteristic of static voltage generator

Abstract

With a large scale of renewable energy connected to the distribution system, the problem of uncertainty will become more obvious due to the huge fluctuation and intermittent characteristics. To ease the effects of uncertainty, static var generator (SVG) is often used to track reactive power fluctuations in the distribution system and compensate. Based on this background, an interval power flow method based on an optimization model is presented in this paper. The tracking characteristic of SVG is involved in this method. The presented method is more efficient and accurate than the existing methods due to its linearized features and considering the tracking characteristic of SVG. Finally, a modified 33-bus distribution system is used to demonstrate the effectiveness of the proposed algorithm.
