An Efficient Method for D-STATCOM Placement in Radial Distribution System

This paper presents an effective method for the identification of candidate bus for DSTATCOM placement for the minimization of power losses and improvement of voltage profile in radial distribution system with load modeling. The DSTATCOM is modeled for determination of its size by assuming the voltage magnitude as 1 p.u. at the candidate bus. The validity of the method is tested on the standard IEEE 33-bus radial distribution system by performing load flow analysis after compensating the candidate bus using MATLAB software. The results obtained are compared without and with the DSTATCOM for all load models. The voltage profile and the losses reduction is obtained for IEEE 33 bus test system with the optimal placement of D-STATCOM based on the sensitivity index.
