This document discusses a novel control strategy to enhance power quality in grid-connected solar systems using a maximum power point tracking scheme and an active filtering method. The effectiveness of the proposed approach is demonstrated through extensive MATLAB/Simulink simulations that validate its capability to function without additional power conditioning equipment. The findings indicate that the grid-interfacing inverter can serve as a multifunction device for power conditioning.

CONCLUSION:
This work has presented a novel control of an existing grid interfacing inverter to improve the
quality of power at PCC. It has been proved that the grid-interfacing inverter can be effectively
utilized for power conditioning without affecting its normal operation of real power transfer.
This approach eliminates the need for additional power conditioning equipment to improve the
quality of power. Extensive MATLAB/Simulink simulation results have validated the proposed
approach and have shown that the grid-interfacing inverter can be utilized as a multi-function
device.

The integration of renewable energy resources with the grid incorporates power electronic converters for conversion of energy. These power electronic converters introduce power quality issues such as a harmonics, voltage regulation etc. Hence, to improve the power quality issues, this work proposes a new control strategy for a grid interconnected solar system. In this proposed work, a maximum power point tracking (MPPT) scheme has been used to obtain maximum power from the solar system and DC/DC converter is implemented to maintain a constant DC voltage. An active filtering method is utilized to improve the power quality of the grid connected solar system. The proposed system is validated through dynamic simulation using MATLAB/Simulink Power system toolbox and results are delivered to validate the effectiveness of the work. KEYWORDS: 1.
