Abstract: Three-phase inverters for grid-connected applications typically require some form of grid voltage phase detection in order to properly synchronize to the grid and control real and reactive power. This phase detection is usually based upon some type of grid voltage sensing.
In the three-phase grid-connected current-source inverters (CSIs), the resonance result from the AC-side CL filter and the quality of the grid-current waveform under the unbalanced and harmonic grid voltage conditions are two issues deserving attention.
At present, the mainstream control strategies for three-phase voltage inverters mainly include vector control and direct power control. But in vector control, the selection of its proportional–integral control parameters can only be obtained by experience, which requires a large amount of experimental data to support.
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.
Three-phase PV inverters are generally used for off-grid industrial use or can be designed to produce utility frequency AC for connection to the electrical grid. This PLECS application example model demonstrates a three-phase, two-stage grid-connected solar inverter.
