Bipolar power control method for sending new energy through flexible DC island

The invention discloses a bipolar power control method for transmitting new energy through a flexible DC island. The method comprises the following steps: acquiring a grid-side voltage of a main control electrode, a reference angle of the main control electrode and a grid-side voltage of a non-main control electrode; obtaining a d-axis current adjusting value and a q-axis current adjusting value through the network side voltage of the main control electrode and the reference angle of the main control electrode; generating a main control electrode reference wave by using the d-axis current adjustment value, the q-axis current adjustment value and the reference angle of the main control electrode; generating a reference angle of the non-main control electrode by combining the grid-side voltage of the non-main control electrode with the dynamically adjusted power of the non-main control electrode; generating a non-main-control-electrode reference wave from the d-axis current adjusting value, the q-axis current a
