The simulations are performed in PLECS that can be used standalone or integrated with MATLAB/Simulink. The three-dimensional space vector modulation technique is implemented as a C-script for the control action of the four-leg VSI. Furthermore, the independent control of each voltage phase at the point of common coupling for standalone operation using the four-leg VSI topology is implemented in a stationary frame to deal with balanced and unbalanced loads in order to improve the power quality that is sent to the AC system.
