Novel PI-Sliding Mode Control of Solar Inverter to Reduce Harmonics and Improve the Quality of Power Injection into Microgrids Containing DGs Along with Performance Analysis in Variable Radiation and Temperature

In this paper, a new method is presented to improve the MPPT tracking and robustness and reduce the output THD of solar inverters against changes in environmental parameters. The proposed control method has been evaluated using simulation in MATLAB/Simulink under different temperature and radiation conditions. The results show that the PI-Sliding Mode method not only improves the output power level but also reduces the power and current fluctuations in both transient and steady states, which indicates the efficiency and robustness of the proposed method. The proposed method decreases THD about ۰.۸% in both current and voltage waveforms.
