“…Extended Kalman filters, as proposed in (Kumar et al, 2006), can be applied to a certain power system bus in order to measure active and reactive powers. (Yu et al, 2005) analyses the dynamical response of Kalman filters during power system transients and proposes an Adaptive Kalman filter in order to improve the performance of the estimation process. In case of (Macías & Exposito, 2006), such problem is solved by applying a selftuning algorithm to the covariance matrix.…”

“…For the optimal choice of the noise covariance matrices, various improved KF algorithms have been applied to power system harmonic state estimation. For example, considering the uncertainty of the process noise covariance matrix, Yu [10] proposed an adaptive Kalman filter method in which two basic Q models can be switched for steadystate and transient estimation. As a comparison, Shih and Huang [11] adjusted the measurement noise parameter R instead of Q to increase the robustness of the EKF method.…”

“…Harmonic State Estimation (HSE) [1,2] involves harmonic distribution and harmonic source identification [3][4][5][6][7][8][9][10]. With regard to the HSE problems, a multitude of methods have been employed, including least squares (LS) [1,2], singular value decomposition (SVD) [4], Kalman filter [5], neural networks (NN) [6], sparsity maximization [7], and particle swarm optimization (PSO) [8]. Additionally, it has been proved that the complete harmonic distribution can be derived based on selected measurement data [5].…”

However, in terms of the HSE methods, precise information on network parameters are required, which are rarely known in practice.…”
