| Abstract | ||
| The paper presents a novel Hybrid-FACTS Based Stabilization Scheme controlled by a hierarchical two-stage fuzzy logic (HFLC)-multi loop dynamic error driven controller. The proposed scheme includes separate Fuzzy control stages for the PD and PID parts to ensure robust and effective dynamic speed control and efficient energy utilization. The PD fuzzy stage used the global error and change of error as the fuzzy input variables. The second stage is the PID-FLC regulation which utilizes the output of the PD-FLC stage and the integral of the global error as input fuzzy variables. The simulation results validate the proposed control scheme effectiveness and robustness with efficient energy utilization, improved power quality and power factor at the Common AC Bus and load bus. A Digital simulation model of the proposed system is developed in Matlab/Simulink/Simpower Software Environment using operational dynamic blocks available in Simulink library. | ||
