D.KulkarniNIE, Department of EEE, Mysuru, INDIAIn recent years, the Electrical Distribution system is operated with the integration of various Distributed Generators close to its working limits. Some of the D-facts devices such as D-STATCOM, DVR, and UPQC are placed in the Distribution system to enhance the power quality and to improve the overall stability of the system but the placement of these D-Facts devices in DG environment is essential for the overall power quality improvement. In this paper, a novel technique is introduced based on weighted multi-objective function with power quality indicators for finding the most sensitive bus concerning power quality disturbance in the Distribution system. The optimal sensitive bus is identified for integration of Power quality disturbance mitigating devices with Rotating and Static Distributed Generators520202052020207279https://www.wseas.org/multimedia/journals/electronics/2020/a185116-654.pdf10.37394/232017.2020.11.9http://www.wseas.org/multimedia/journals/electronics/2020/a185116-654.pdfManjunatha.
