Appropriate design and usage of Unified Power Flow Controller (UPFC), which has the ability of controlling the busbar voltage levels and transmission line power flows simultaneously, provide a suitable conditions to enhance operation of restructured power systems. In this paper, a novel control method using four degrees of freedom is represented for hysteresis based UPFC as well as a straight f...

The present paper describes the steady-state response and control of power in transmission line equipped with FACTS devices. Detailed simulations are carried out on two-machine systems to illustrate the control features of these devices and their influence to increase power transfer capability and improve system reliability. The DPFC is derived from the unified power-flow controller (UPFC) and ...

This paper investigates the matrix converter when working as the unified power flow controller which can regulate the active reactive power flowing in a transmission line. A conventional unified power flow controller usually has a DC capacitor; this is removed in the proposed controller. This reduces the volume, improves the efficiency and lifetime, and eliminates the DC voltage control. The de...
