Abstract
In order to evaluate the approximate expression of power flow Jacobian matrix, some indices are established according to the relation of singular values between the symmetric part and skew-symmetric part of power flow Jacobian matrix. The comparisons of indices not only include the comparisons of 2-norm and F-norm, but also include the comparisons of the weighted sum of singular values, these indices can also be applicable to complex matrix. The simulations on IEEE30 system show the effectiveness.
