This paper presents a direct power control (DPC) for three-phase matrix converters operating as unified power flow controllers (UPFCs). Matrix converters (MCs) allow the direct ac/ac power conversion without dc energy storage links; therefore, the MC-based UPFC (MC-UPFC) has reduced volume and cost, reduced capacitor power losses, together with higher reliability. Theoretical principles of direct power control (DPC) based on sliding mode control techniques are established for an MC-UPFC dynamic model including the input filter. As a result, line active and reactive power, together with ac supply reactive power, can be directly controlled by selecting an appropriate matrix converter switching state guaranteeing good steady-state and dynamic responses. Experimental results of DPC controllers for MC-UPFC show decoupled active and reactive power control, zero steady-state tracking error, and fast response times. Compared to an MC-UPFC using active and reactive power linear controllers based on a modified Venturini high-frequency PWM modulator, the experimental results of the advanced DPC-MC guarantee faster responses without overshoot and no steady-state error, presenting no crosscoupling in dynamic and steady-state responses.

“…Although conventional power system stabilizers (PSSs) are widely used by power system utilities, their use cannot develop sufficient damping to interarea modes and more efficient alternatives are needed other than PSSs [4]. In this study, two members of the converter-based FACTS devices are considered for oscillation damping: the interline power flow controller (IPFC) [5][6][7][8] and static synchronous series compensator (SSSC) [9][10][11].…”

This paper develops a novel self-tuned fuzzy damping control scheme for an interline power flow controller (IPFC) to suppress the interarea mode of oscillations in a multimachine power system. The nonlinear adaptive damping controller is based on coordinated operation of two fuzzy inference systems. The first one produces the required q -axis voltage reference of the quasi multipulse series converter in response to generator angle oscillations, while the second one is used to tune the output of the first one online for further reducing the error signal using a given set of fuzzy rules. The simplex method is employed to search for optimal gains of the damping controller by minimizing the objective function in which speed deviations between generators are formulated. The feasibility of the proposed technique is validated using time-domain simulation cases in the PSCAD simulation program. It is also shown that the proposed damping scheme for IPFC works better than the static synchronous series compensator, which utilizes the same damping scheme in reducing the interarea mode of oscillations.

Summary The harmonic response and interaction of the unified power flow controller and the electrical network are presented in this paper. A UPFC model for harmonic studies is presented; this model incorporates all the basic operating characteristics that existing fundamental frequency UPFC models offer, such as active and reactive power regions. However, the harmonic model offers richer information such as harmonic distortion regions. The UPFC model is given in the form of equivalent impedance, which is connected to the AC system to perform harmonic propagation and resonance prediction analysis. By resorting to modularity, the UPFC model is obtained as the connection of two voltage source converters with the AC system and between themselves. The model is used to study the harmonic response of the UPFC and its interaction with the transmission lines. Copyright © 2014 John Wiley & Sons, Ltd.
