“…The employed model allowed the external synchronisation mechanism to be avoided. (Kwan et al, 2007), (Elnady & Salama, 2007) and (Griffo et al, 2007) proposed Kalman filters in order to control a Unified Power Quality Conditioner which allows both grid and load disturbances to be compensated. Kalman filters have been also successfully applied to electrical grid management issues and electrical loads forecasting.…”

“…In the matter of power conditioning, several closed-loop control schemes have been applied in order to control the voltages and currents waveforms, frequency, and amplitudes of an electrical load or point of common coupling (PCC) (Peng, 2001). Many control laws can be used in order to guarantee the voltage/current to track the references, and to compensate for disturbances, running from classically inspired techniques (Marafão et al, 2008) to those including a KF in the control loop (Moreno et al, 2004;Kwan et al, 2005;Rosendo et al, 2007). An active rectifier, e.g., should drain a sinusoidal current from the supply system, which should be in-phase with the fundamental component of the grid voltage, even if this one is distorted.…”

“…However, their capabilities are usually limited as they can only solve one or two power quality (PQ) problems. Recent research efforts have been made toward utilizing a device called UPQC to solve almost all PQ problems [5].

This paper presents a novel control strategy for selective compensation of power quality (PQ) problems, depending upon the limited rating of voltage source inverters (VSIs), through a unified power quality conditioner (UPQC) in a three-phase four-wire distribution system. The UPQC is realized by the integration of series and shunt active power filters (APFs) sharing a common dc bus capacitor. The shunt APF is realized using a three-phase, four-leg voltage source inverter (VSI), while a three-leg VSI is employed for the series APF of the three-phase four-wire UPQC. The proposed control scheme for the shunt APF, decomposes the load current into harmonic components generated by consumer and distorted utility. In addition to this, the positive and negative sequence fundamental frequency active components, the reactive components and harmonic components of load currents are decomposed in synchronous reference frame (SRF). The control scheme of the shunt APF performs with priority based schemes, which respects the limited rating of the VSI. For voltage harmonic mitigation, a control scheme based on SRF theory is employed for the series APF of the UPQC. The performance of the proposed control scheme of the UPQC is validated through simulations using MATLAB software with its Simulink and Power System Block set toolboxes.
