    Model Predictive Current Contro l of Shunt Active Power Filter C onnected to a Photovoltaic S ystem

    This research work presents a predictive current control of shunt active power filter connected with PV system, the main goal of the proposed active filtering system is to eliminate the undesirable harmonics. Shunt active power filter need a supply of energy for recompensing this based mostly deformations, which use the electrical phenomenon array with DC-DC boost converter as a supply of DC power. Therefore, to improve the efficiency of the energy conversion it is a necessary track permanently the optimum point through an adequate tuning of a boost converter regardless the solar irradiance variations. However, predictive current control is applied to control a three-phase voltage source inverter used as a shunt Active power filter. This method chooses a switching state that minimizes the error between the output currents and their references. The proposed controller offers excellent reference tracking with less current harmonic distortion. Finally, the proposed system's performance is investigated using a MATLAB simulation model.

    Predictive Current Controlled Shunt Active Power Filter Working under Unbalanced Supply Conditions
    (University of eloued جامعة الوادي, 2016-10-28) Mesbahi, Nadhir; Ouari, Ahmed; Omeiri, Amar; Bouchikha, Hocine
    This paper has presented a predictive current control method of shunt active power filter (SAPF) under unbalanced supply conditions. Two parts are included: one is the computation of compensating reference current of SAPF and the other is predictive current control for SAPF to track the current reference. The reference current computation method is based on the use of high selectivity filters (HSF). The use of HSF instead of classical extraction filters (low pass filters) allows extracting directly the voltage and current fundamental components in the α-β axis without phase locked loop (PLL). The performance of the proposed algorithm is evaluated by means of computer simulations using Matlab/Simulink.
