In this work, a unique adaptive algorithm is successfully designed, controlled, and verified. For the grid voltage source converter (VSC) system, the suggested approximate multiplier least mean square (AM-LMS) management method effectively mitigates power disturbances without compromising power quality (PQ). Additionally, the VSC control method adds multipliers to the finite impulse response (FIR) filter and updates the coefficients of the circuitry to reduce the complexity of the LMS. Since it is more economical and reliable than other grid sides, the AC side is used. On the DC side, a bidirectional DC-DC converter and a photovoltaic (PV) array form the insular micro grid for which the VSC management is intended. On the DC side, a bidirectional DC-DC converter and a photovoltaic (PV) array form the insular micro grid for which the VSC management is intended the efficacy and validation of the suggested controller are guaranteed by the experiment findings. These results are considered satisfactory, with enhanced dynamic and steady state functionality and overall harmonic distortion of grid currents that meets the IEEE-519 standard resolution.
