Performance degradation is, in general, regarded as a power quality problem. One solution to recover grid performance is through the application of unified conditioner (UPQC). Although these devices are multi-input/multi-output (MIMO) systems, most common control strategies consist two decoupled controllers, which neglect coupling effects and add uncertainty system. For this reason, paper propo...

The main aim of this project is ,this topology enables UPQC to have a reduced dc-link voltage without compromising its compensation capability. Three-phase, four-wire unified Power Quality (UPQC) to improve power quality. The UPQC is realized by the integration of series and shunt active power filters (APF) sharing a common dc bus capacitor. The realization of shunt APF is carried out using a t...

This paper mainly deals with the regulation of voltage at wind farm (WF) terminals and the improvement of power quality and WF stability in a WF to Weak-Grid connection. In facilities with moderated power generation, the WF are connected through medium voltage (MV) distribution headlines. A situation commonly found in such scheme is that the power generated is comparable to the transport capaci...

Abstract This paper proposes a cascaded low-pass filter (CLPF) scheme for the control of unified power quality conditioner (UPQC) installed enhancing an electric vehicle (EV) charging station. With incorporation UPQC, EV station draws sinusoidal currents at unity factor and supply voltage is maintained nominal value charger input. In CLPF scheme, α–β components load current are individually pro...
