“…In order to achieve successful power conversion based on RES, components like rectifiers, boost converters, and inverters are crucial [8]. Since the use of different inverters and loads, which are nonlinear, the grid experiences a variety of disruptions [9]. The harmonic of the gird current typically produces considerable heat and causes insulation degradation due to increased losses [10].…”

This research proposed a cascaded multi-level inverter (CMLI) technique using Harris Hawk’s Optimisation (HHO) for grid-connected P.V. systems. The photovoltaic (P.V.) system is connected to CMLI-isolated DC connections based on the relevant D.C. to D.C. converters. The main goal of the suggested approach is to control power or boost solar system energy conversion while maintaining power quality. CMLI is integrated into fewer switches, diodes, and sources to produce the best control signal with the suggested controller. To provide the best control signal data set for the CMLI, the gain parameter under the source's current normal value is assessed using the HHO. The proposed control theory and keeping the power factor constant control the active power fed to the grid. The suggested approach of integrating solar electricity into the grid using DC-DC converters and an asymmetric multi-level inverter structure is supported by the reduction in THD and active power to the grid. The suggested model is developed using the MATLAB/SIMULINK programme, and the experimental setup is used to validate the results. On the grid side, lower THD was attained, which complies with IEEE standards. .
