Optimal location and sizing of Distribution Static Synchronous Series Compensator using Particle Swarm Optimization

•This paper describes the power quality improvement using PSO.•Optimal placement and sizing of DSSSC is done.•Analysis is carried out on 12 and 69 bus radial distribution systems.•Output of PSO is compared with the results obtained from the analytical method. This paper describes the power quality improvement using Particle Swarm Optimization for optimal placement and sizing of Distribution Static Synchronous Series Compensator in radial distribution networks. In this analysis, enhancement of power quality includes improvement of voltage and reduction of line losses. A complete performance analysis is carried out on 12 and 69 bus radial distribution systems to demonstrate the effectiveness of the proposed work. The results show that the placement of DSSSC in radial distribution systems effectively improves the voltage of a system and reduces the power losses. MATLAB, Version 7.10 software is used for simulation.
