Mitigation Of Inter Harmonics In Pv Systems With Maximum Power Point Tracking Modification

In this project the interharmonics to emerging the power quality challenges in grid-connected photovoltaic systems. The main problem of interharmonics can cause grid voltage fluctuations, flickering and unintentionally disconnection of the PV system. The perturbation of the PV array voltage during the maximum power point tracking (MPP) searching inevitably induces power oscillations at dc side, especially during the steady-state condition. To control these issues a new mitigating solution for inter harmonic in a PV system is proposed. In this method sampling rate value consider randomly between fast and slow value. The results of proposed inter harmonic mitigation can be evaluated by using Mat lab/Simulink.
