<span>This paper presents the harmonic reduction performance of proportional resonant (PR) current controller in single phase inverter system connected to nonlinear load. In the study, proportional resonant current controller and low pass filter is discussed to eliminate low order harmonics injection in single phase inverter system. The potential of nonlinear load in producing harmonics is showed and identified by developing a nonlinear load model using a full bridge rectifier circuit. The modelling and simulation is done in MATLAB Simulink while harmonic spectrum results are obtained using Fast Fourier Transfor. End result show PR current controller capability to overcome the injection of current harmonic problems thus improved the overall total harmonic distortion (THD).</span>

The autonomous photovoltaic system requires a battery for storage of energy, for consumption during the night and days with low irradiation. This article presents the design and control of the autonomous PV system with a storage battery and a single-phase inverter. The SEPIC converter is used to adapt the output voltage of the PV panel to the battery charging voltage, this converter is controlled by the intelligent MPPT control followed by PI controllers to extract the maximum power of the GPV and manage the charge and discharging loop the battery. Subsequently, a BOOST converter has been associated with the system to adapt the output voltage of the battery to the load. The modelling of the state space is done to determine the transfer function of the converters (SEPIC and BOOST). The single-phase inverter is used to supply alternative loads. The values of the PI correctors (Kp and Ki) are obtained using the method of Ziegler Nichols. Finally, we simulated and analysed the performance of a 250W stand-alone photovoltaic power system on MATLABSimulink.
