Reactive Power Optimization of UPFC System Based on Particle Swarm Optimization

The introduction of new intelligent components in the power system produces more harmonics, and UPFC can adjust them well. For improving the effectiveness of performance parameters of the power system, a reactive power optimization method based on particle swarm optimization considering UPFC is proposed. Through the paper, the energy parameter with UPFC is calculated under the way of the power injection model, and the objective function is to minimize the energy loss in the system. On this basis, reactive power optimization is realized by particle swarm optimization. Under the background of the simulation of the IEEE9 bus, the results of system parameters before and after using particle swarm optimization in UPFC are analyzed. It is found that the proposed method has a good advantage to improve the system network loss and optimize the system quality, which has good practical value.
