The Effect of the New Adaptive HCC for SAPF in a Grid Connected Photovoltaic System
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 1
Abstract
In this paper, a new iterative method for calculating adaptive hysteresis band current controller is proposed for Hysteresis Current Controller (HCC) in the grid connected photovoltaic (PV). The adaptive hysteresis band current controller, proposed by Bose for electrical machine drives, is adapted to active power filter (APF).The adaptive hysteresis band current controller changes the hysteresis bandwidth according to modulation frequency, supply voltage, dc capacitor voltage and reference current wave. The hysteresis band current controller determines the switching times of the shunt active power filter (SAPF). The results of simulation study of the SAPF control technique presented in this paper is found quite satisfactory to compensate reactive and harmonic components of the local loads and inject generated active power of the photovoltaic cells into the grid. The fix band hysteresis current control and the adaptive hysteresis band current control are equally good in filtering the harmonics generated by the load. The main difference between the two control methods should be in the high frequency harmonics generated by switching of the IGBTs. The instantaneous switching frequency remains constant in the proposed method contrary to conventional fix band hysteresis current control method. All simulation is done using MATLAB/Simulink.
