Abstract The present research motivates the enhancement of power quality in a PV fed DSTATCOM employed in a local distribution network. As per the power quality demand from the consumer, regulation of power has become major focus in presence of renewable systems in the distribution network. The distribution network majorly shows resistance towards the severe uncertainties of the grid and load variations. Therefore, the present research proposes hybrid DSTATCOM for the distribution system with various uncertain load conditions. To enhance the performance of proposed system, a robust SRF controller has been implemented for the generation of reference signal for VSI of the DSTATCOM along with DC offset error compensation (DOEC) based phase-locked loops. In the Hybrid DSTATCOM, regulation of dc-link voltage also plays significant position for the performance of the system. Therefore, in this research paper, bat optimization based MPPT has been implemented for the regulation of dc link voltage at the desired level. The system has been developed in the Matlab/Simulink and results have been analyzed. The system has been also validated under experimental conditions in the laboratory, which shows the systems efficiency.
