Abstract
In a Hierarchical Model Predictive Control (H-MPC) framework, this paper
explores suitable time-variant structures for the hierarchies of different
local MPC controllers. The idea is to adapt to different operational conditions
by changing the importance of the local controllers. This is done by defining
the level of the hierarchy they belong to, and solving within each level the
local MPC problem using the information provided by the higher levels at the
current time step and the predicted information from the lower levels obtained
in the previous time step. As selecting a hierarchy results in a combinatorial
optimization problem, it is explicitly solved for a limited number of relevant
topologies only and then the switching between topologies is defined with a
multiobjective optimizer, so as to decide the best H-MPC scheme according to
the expected performance. A comparison with fixed-topology H-MPC controllers is
done, showing the effectiveness of the proposed approach for the power control
of a hydro-power valley.
