MATLAB/Simulink Based Simulation of a Hybrid Power Flow Controller

A number of Flexible AC Transmission System (FACTS) controllers based on the rapid development of power electronics technology have been proposed in recent years for better utilization of existing transmission facilities. FACTS devices have shown very promising results when used to improve power system steady-state performance. They have been very promising candidates for utilization in power system damping enhancement. Hybrid Power Flow Controller (HPFC) is proposed in the present work as it can be used to replace or supplement the existing equipments. Usually, it can be installed at locations already having the reactive power compensation equipment´s like the SVC, STATCOM etc. In this Paper author designed HPFC model using MATLAB/Simulink software and study of the power system stability enhancement by implementing the HPFC in SMIB System power system. The system also has the provision of a comparative study of the performances of UPFC and HPFC regarding power system stability enhancement of the system. Results obtained are encouraging and indicate that the designed model has very good performance which is comparable to the already existing UPFC.
