| description | The invention discloses an inverter improved control method and system for a low-voltage power distribution network. The method comprises the following steps: acquiring reference values of d-axis and q-axis voltages in inverter control, output data of a phase-locked loop and rated angular frequency of a power grid; based on the negative resistance characteristic of the phase-locked loop, in combination with the collected output data of the phase-locked loop and the rated angular frequency of the power grid, the reference values of the d-axis voltage and the q-axis voltage are calculated, and a voltage compensation value is obtained; and smoothing the voltage compensation value by using a dynamic adjustment algorithm, filtering through a filter to obtain an optimized voltage compensation value, and feeding back the optimized voltage compensation value to a d axis and a q axis in inverter control. According to the invention, negative feedback regulation is ingeniously introduced into the current vector control |
