Optimal location and sizing determination of Distributed Generation and DSTATCOM using Particle Swarm Optimization algorithm

•DG and DSTATCOM are placed to reduce the total power loss.•Three test systems are considered.•Each test systems are analyzed using five different cases.•PSO algorithm is used for optimization work.•Loss Sensitivity Factor is used to analyze the results.

A Particle Swarm Optimization algorithm for finding the optimal location and sizing of Distributed Generation and Distribution STATicCOMpensator (DSTATCOM) with the aim of reducing the total power loss along with voltage profile improvement of Radial Distribution System is proposed in this paper. The new-fangled formulation projected is inspired by the idea that the optimum placement of the DG and DSTATCOM can facilitate in minimization of the line loss and voltage dips in Radial Distribution Systems. A complete performance analysis is carried out on 12, 34 and 69 bus radial distribution test systems and each test system has five different cases. The results analyzed using Loss Sensitivity Factor shows the optimal placement and sizing of DG and DSTATCOM in Radial Distribution System effectively improves the voltage profile and reduces the total power losses of the system.
