Policies and ethics The control of grid-connected inverters has attracted tremendous attention from researchers in recent times. The challenges in the grid connection of inverters are greater as there are so many control requirements to be met. The different types of control techniques...
The traditional model predictive current control methods of grid-connected inverters mainly include grid-connected current prediction, objective function minimization, delay compensation, and voltage vector selection.
Aimed at the issues of the fixed range of vector selection, fixed amplitude, and fixed direction in the conventional single and double vector model predictive control for grid-connected inverters, such as the large current pulsation and poor steady-state performance of the system, a three-vector model predictive control strategy is proposed.
The grid-connected PV system control diagram for a three-phase inverter is depicted in Fig. 2.5. It involves the application of a cascaded control loop. The external loop consists of controlling the active and reactive power by PQ controller. It may also consist of indirect control through a DC-link voltage controller.
In conclusion, it is evident that this work has presented a robust current control for three-phase grid-connected inverters based on a super twisting sliding mode algorithm.
