Robust Kalman Filter-Based Dynamic State Estimation of Natural Gas Pipeline Networks [PDF]

open access: yesMathematical Problems in Engineering, 2021
To obtain the accurate transient states of the big scale natural gas pipeline networks under the bad data and non-zero mean noises conditions, a robust Kalman filter-based dynamic state estimation method is proposed using the linearized gas pipeline transient flow equations in this paper. Firstly, the dynamic state estimation model is built.
