An Adaptive Hysteresis Current Control for SAPF in a Grid Connected Photovoltaic System

In this paper, an adaptive hysteresis band currentcontroller is proposed for Hysteresis Current Controller (HCC)in the grid connected photovoltaic (PV) system. The adaptivehysteresis band current controller, proposed by Bose forelectrical machine drives, is adapted to active power filter (APF).The adaptive hysteresis band current controller changes thehysteresis bandwidth according to modulation frequency, supplyvoltage, dc capacitor voltage and reference current wave. Thehysteresis band current controller determines the switching timesof the shunt active power filter (SAPF). The results of thesimulation study of the SAPF control technique presented in thispaper is found quite satisfactory to compensate reactive andharmonic components of the local loads and inject generatedactive power of the photovoltaic cells into the grid. All simulationis done using MATLAB/Simulink.
