  "textContent": "A power distribution system (10) comprises a power conversion module (12) for performing power conversion between a DC voltage at a DC side (14) and an AC power at an AC side (16), and a conversion control system. The AC side of the power conversion module is electrically coupled to a grid (18). The conversion control system includes a phase-locked-loop circuit (32) for receiving a multi-phase reference signal (40) of a grid voltage and for generating a synchronized signal (42), a regulator (52) for receiving reference commands, a two-phase grid feedback signal, and the synchronized signal and for generating a control signal for the power conversion module, and a phase compensation circuit (64) for receiving the synchronized signal and the multi-phase reference signal of the grid voltage, for obtaining a phase displacement signal (70), and for generating a phase compensation signal (66) for compensating the reference commands or for compensating the synchronized signal when the phase displacement signal exceeds a threshold value.",
