Optimal placement and sizing of DG based on power stability index in radial distribution system

This paper proposes a new algorithm for Distributed Generator placement and sizing in radial distribution system based on a novel index. The index is developed considering stable node voltages referred as power stability index (PSI). A new analytic approach is adopted to visualize the impact of DG losses, voltage profile, and voltage stability. The proposed method is tested on 12-bus and 69 bus radial systems.
