Abstract :
In this article, a multi-objective function for placement of Distributed Generation (DG) and capacitors with thetap setting of Under Load Tap Changer (ULTC) Transformer is introduced. Most of the recent articles have paidless attention to DG, capacitor placement and ULTC effects in the distribution network simultaneously. Insimulations, a comparison between different modes was carried out with, and without tap setting of ULTC.Simultaneous DG, capacitor placement, and ULTC transformer tap setting improve the voltage profile of loadbuses globally. In addition, they can also reduce loss and increase Available Transfer Capability (ATC). TheIEEE 41-bus radial distribution network is used to illustrate the effectiveness and feasibility of the proposedapproach.
