a configuration method of grid-forming converters based on capacity sensitivity is proposed
which considers the influence of the access positions of grid-forming converters in a wide frequency range. Firstly
the stability margin of the system is measured based on the key eigenvalues of the return ratio matrix. Secondly
the capacity sensitivity of the key eigenvalues to the grid-forming converters with different access positions is calculated. The weak nodes of the system are screened by the capacity sensitivity
and the siting planning of grid-forming converters prioritizes weak nodes. Finally
the effectiveness of the proposed method is verified by PSCAD simulation.
