The grid phase currents (converted to dq-axis currents) and the DC bus voltages are measured in the GSC controller. The DC bus voltage is regulated by a control loop where the output is the reference d-axis current for the current regulator, Id_ref(GSC bus). It should be noted that Id(GSC bus) is the current that is in the same phase with the grid voltage, which controls the active power. The current regulator in the inner loop controls the magnitude and phase of the output voltage of the GSC (V(GSC bus)).

The reactive power at the GSC bus is initially taken to be zero. Then the voltage at GSC bus can be obtained. Further, the offshore current can be calculated. The reactive power at wind farm bus is calculated which is the power required by the reactance associated with GSC and is to be compensated by the converter. This reactive power is added to the reactive power of GSC converter bus. The process is repeated until the reactive power at wind farm bus is zero.
