Objectives: One of the drawbacks of the power system network, i.e. Optimum Reactive Power Dispatch (ORPD) is optimized. Due to this, system transmission power losses and bus voltage magnitudes are optimized Methods/Statistical Analysis: A unique optimization rule, Uniformly Distributed Two-stage Particle Swarm Optimization (UDTPSO) are enforced in conjunction with the traditional Particle Swarm Optimization (PSO).The power injection model for the Generalized Unified Power Flow Controller (GUPFC) is used to enhance the power flow in a power system network. Findings: The proposed technique has fast convergence rate in less number of iterations which validates the effectiveness of UDTPSO. The study is tested on a standard IEEE-30 bus system and the results obtained with UDTPSO are valid with the existing PSO. Applications: Effective utilization of a Flexible Alternating Current Transmission system (FACTS) device called Generalized Unified Power Flow Controller (UPFC) for power flow control which will improve existing transmission capability.
