Enhancement of Power Quality in Grid Connected Photovoltaic System Using Predictive Current Control Technique

Now- a days the increased use of power electronic devices has resulted in power quality problems such as voltage sag, swell, harmonics and voltage flicker. Non-linear loads affect system power quality. PV systems are grid connected via an interfacing converter. Single phase shunt active power filter (APF) can be used to develop the power quality in terms of current harmonic mitigation and reactive power compensation. In this paper a PV interfacing inverter which acts as a shunt an APF is controlled using predictive current control (PCC) technique for current harmonics mitigation. The MATLAB Simulink model is used to study the performance of system
