AI Technical Summary
Grid-connected converters are prone to coupling with grid impedance under weak grid conditions, leading to oscillations and instability. Traditional grid-connected control cannot operate stably.
A hybrid control method combining grid-following and grid-building is adopted. Through the synergistic effect of synchronization deviation inertial response and power error compensation, the target modulation signal of the converter is generated, thereby achieving stable synchronization and power balance between the converter and the power grid.
It improves the stability and adaptability of the converter under different power grid conditions, avoids the risk of phase-locked loop oscillation, and achieves the unity of synchronous tracking performance and power regulation.
