This study presents a modified variable step size (VSS) least mean square (LMS)‐based control for improving the performance of a single‐stage photovoltaic (PV) integrated grid system. Here, a three‐phase, three‐wire, single‐stage grid system consists of three‐phase voltage source converter, PV module, filters and loads. Main motive of the considered system with the adaptive control algorithm is to achieve desired voltage at the point of common coupling, load balancing, unity power factor and harmonics elimination while transferring power to grid as well as loads. The system with modified VSS‐LMS‐based control algorithm is simulated using MATLAB/Simulink environment and an experimental prototype is developed in the laboratory to verify the efficacy and performance of proposed algorithm.
