Complex power systems can be regarded as systems of systems interacting with each other over multiple time scales and energy domains. For example, aircraft and automotive electric vehicles (EVs) have systems spanning electrical, thermal, and mechanical domains with dynamics operating at the sub-milliseconds time scale in the electric domain and the minutes time scale in the thermal domain.
Hierarchical control has been shown to manage the coupling between the highly transient dynamics and slow dynamics resulting from the nature of complex power systems. One of the main advantages of a hierarchical control approach, compared to a centralized control approach, is the ability to predict the performance of the system far enough into the future at the upper level of the hierarchy as well as to respond quickly to unknown disturbances at the lower-level of the hierarchy at a relatively small computational cost. To accomplish this, the majority of control design work in the literature assumes full state feedback; it is usually assumed that there is a sensor that measures every state in the system. However, in practice, it is often infeasible or prohibitively expensive to measure every state of the system. A more reasonable approach is to estimate unmeasured states using a model of the system and a set of sensor measurements.
My current research focuses on developing a multi-level hierarchical estimation framework that supplies accurate state estimates to hierarchical controllers of complex power systems.
