Vector switching converter VeSC has been recently introduced as an alternative for controlling power flow in power system's complex interconnections by direct AC-AC conversion, and novel FACTS devices have been recently introduced based on the VeSC, such as the Xi (Xi) and Gamma (Gamma) controllers. This paper introduces the simplified vector switching converter SVeSC and the topology of the Xi (Xi)...
This paper is aimed for presenting the analysis of ac-ac converters taken into account unbalanced conditions. Analytical expressions for the output voltage and currents are presented. The major aim of the followed strategy is to control the Parkpsilas vector of the output-voltage, and to control the phase between the input-voltage and the input-current. This allows: (a) to have balanced output-voltages...
Here the analysis on the inclusion of a pulse width modulated (PWM) ac link unified power flow controller into a power flow program is discussed. Similarly, a PWM series compensator is connected to the power system to regulate the active power flow on the corresponding transmission line. Details of the Newton-Raphson's power flow algorithm are exhibited. Results of simulation are presented on a 39-buses...
