Robust Dynamic State Estimation of Synchronous Machines with Asymptotic State Estimation Error Performance Guarantees
Sebastian Nugroho, Ahmad F. Taha, Junjian Qi
A robust observer for performing power system dynamic state estimation (DSE) of a synchronous generator is proposed. The observer is developed using the concept of $\mathcal{L}_{\i…
Robust Cubature Kalman Filter for Dynamic State Estimation of Synchronous Machines under Unknown Measurement Noise Statistics
Yang Li, Jing Li, Junjian Qi +1
Kalman-type filtering techniques including cubature Kalman filter (CKF) does not work well in non-Gaussian environments, especially in the presence of outliers. To solve this probl…
Characterizing the Nonlinearity of Power System Generator Models
Sebastian A. Nugroho, Ahmad F. Taha, Junjian Qi
Power system dynamics are naturally nonlinear. The nonlinearity stems from power flows, generator dynamics, and electromagnetic transients. Characterizing the nonlinearity of the d…
