Abstract:  In this talk we will showcase the application of optimal estimation and filtering techniques to two types of systems of interest to the energy community. In the first part we will review some recent results in modeling the closed-loop steady-state behavior of gas turbines based on a combination of computer experiments and experimental field data. The goal is to be able to assess the current state of the turbine and predict key quantities vital to the operation of the machine based on a limit number of sensors. In the second part we will revisit the problem of estimating currents and voltages in three-phase electrical systems using Kalman filters. Kalman filters have been widely used in this type of application for many years in a number of setups. We will show that some of these setups can lead to suboptimal performance if care is not used when characterizing the underlying noise properties and will also establish conditions under which optimality is indeed attained.
