Optimal Placement and Sizing of DSTATCOM in Radial Distribution System Using Gravitational Search Algorithm

Abstract

In order to reduce power losses and improve the voltage profile of the Radial Distribution network, a Gravitational Search Algorithm (GSA) is described in this work. A backward forward load flow algorithm is taken as a base case and Loss Sensitivity Factors (LSF) are used for identifying the candidate buses for D-STATCOM placement whereas the optical allocation and sizing of D-STATCOM is done by using GSA. The proposed work has been evaluated using the industry-standard IEEE 33-Bus Radial Distribution Test network. The acquired results have been compared with the results obtained in Base Case, Genetic Approach (GA), Immune Algorithm (IA), Harmony Search Algorithm (HSA), Power Loss Index (PLI) technique, and Differential Evaluation Algorithm in order to verify the usefulness of the proposed algorithm (DEA). MATLAB software was used to run the simulation.
