A partially linearized sigma point filter for latent state estimation in nonlinear time series models [PDF]

, 2010
A new technique for the latent state estimation of a wide class of nonlinear time series models is proposed. In particular, we develop a partially linearized sigma point filter in which random samples of possible state values are generated at the ...

Learning-Aided Optimal Power Flow Based Fast Total Transfer Capability Calculation

Energies, 2022
Total transfer capability (TTC) is a vital security indicator for power exchange among areas. It characterizes time-variants and transient stability dynamics, and thus is challenging to evaluate efficiently, which can jeopardize operational safety.
