In this paper an unscented Kalman filter with guaranteed positivesemidefinite state covariance is proposed by calculating the nearest symmetricpositive definite matrix in Frobenius norm and is applied to power systemdynamic state estimation. The proposed method is tested on NPCC 48-machine140-bus system and the results validate its effectiveness.
