An improved configuration of the hybrid flow controller (HFC) is introduced to continuously adjust the power flow. In this configuration, a thyristor-controlled series capacitance (TCSC) is added to the conventional HFC to provide continuous variation in the HFC reactance. Moreover, simple closed-loop control methods are designed by considering all the practical constraints of TCSC for this improved HFC (IHFC) and another hybrid arrangement, which is called hybrid power flow controller. Furthermore, to compare and highlight features of the IHFC, simulation results of the designed controllers are carried out in different operating conditions and disturbances. This study also provides a quantitative comparison of various hybrid flexible AC transmission system devices.
