Optimal Reactive Power Dispatch(ORPD) using Particle Swarm Optimization(PSO)

I have solved the optimal reactive power dispatch problem using Particle Swarm Optimization algorithm for IEEE 30 bus test system.Control variables like reactive power output of generators (generator bus voltages), tap ratios of transformers and reactive power output of shunt compensators like capacitors etc. have been optimized by PSO algorithm to minimize the total transmission active power losses while satisfying a given set of constraints.
