HVDC transmission is an integral part of various power system networks. This article presents an Unscented Kalman Filter dynamic state estimator algorithm that considers the presence of HVDC links. The AC - DC power flow analysis, which is implemented as power flow solver for Dynamic State Estimation (DSE), creates an updated admittance matrix. First, a hybrid AC/DC network model is developed to combine the AC network and DC links. Then a non-linear state estimator can solve for hybrid AC/DC states by applying the unscented Kalman filter (UKF) algorithm. It is demonstrated that UKF is easy to implement and accurate in estimation. The dynamic state variables of multi-machine power systems, which are generator rotor speed and rotor angle, are estimated to study transient behavior of the power system network. Finally, a dynamic state estimation model is built for a 14 bus power system network to evaluate the proposed algorithm for hybrid AC/DC networks.
