Multi-level inverters (MLIs) are imprescindibly utilised into grid-connected systems, like renewable energy systems and industrial applications, owing to their capability for generating high-quality output waveforms with low Total Harmonic Distortion (THD). Unlike standalone applications, control systems running over these inverters are responsible for maintaining system stability, grid compliance, and efficiency. This work presents a comprehensive study of the optimisation of control algorithms specifically for the application of MLIs in grid-connected systems. The study aims to enhance significant performance criteria while ensuring grid code compliance concerning dominant harmonic waves THD, Power factor, and efficiency. Expert controllers such as SVPWM, MPC, and hybrid techniques demonstrated substantial overdrafts in inverter performance. Simulation and experimental data indicates that the proposed methods can benefit in performance enhancement of the MLIs in grid-connected conditions.
