Abstract：After frequency disturbances occur in the external power grid，grid-forming converters（GFCs）are

prone to synchronization instability. Analysis shows that adding a low-pass filter（LPF）to the active loop can cause

conflicts between the transient stability and frequency stability of GFC，while adding LPF to the reactive loop can

improve both transient stability and frequency stability，but the improvement in frequency stability is limited.

Therefore，a reactive power angular frequency deviation feed-forward control method was proposed，which can

increase the damping ratio of the GFC power loop，reduce frequency overshoot，not only avoid the conflict between the transient stability and frequency stability of GFC，but also effectively enhance the transient stability and

frequency stability of GFC，making GFC meet the frequency stability requirements of the power system. Finally，

simulation and experimental results validate the correctness and effectiveness of the proposed method.
