The response of the DSTATCOM-BESS system with the nonlinear load is depicted in Figure 4.6. It has been visualized that the ICCT is initially fixed in the constant current control mode operation. Hence, the system’s other load is removed in order to demonstrate the off-peak condition and under this condition, batteries are now starting to charge. Also, due to efficient control, the reference voltage is regulated in order to maintain a constant charging current. It has also been seen that the DSTATCOM provides a compensating current to maintain the source current and voltage sinusoidal and is balanced by keeping the terminal voltage at its calculated reference voltage. Moreover, the source current harmonics and load current harmonics are illustrated in Figures 4.7 and 4.8 and are visualized at 0.44% and 30.31%, respectively, which shows the proposed system’s superiority.
