This paper presents a single-phase voltage distribution static synchronous compensator which integrates a single-phase to three-phase four-wired transformer-less conversion. Beyond that, this structure are capable to interface a distributed alternative energy generation to the mains. The major advantage of this circuit is the combined operation capability, which is realized with a few switching components...
The massive integration of distributed generation (DG) can cause voltage disturbances at the connection points. In order to maximize the penetration of DG power, the actual topology of distribution grids should change introducing active devices to control the voltage, especially in weak networks. In this paper it is analyzed the integration of DG in a weak network connected to a MV/LV substation,...
In this paper, a novel principle of a power quality conditioner based on controllable impedance is proposed for high voltage AC power distribution systems application. A linear transformer is employed to act as controllable impedance under the control of power electronic inverter. On the one hand, the transformer can always exhibit nearly zero impedance to harmonic current. Thus, the harmonic current...
