Abstract

This paper addresses the evaluation of the impact
of non-ideal communication networks on system performance of
hierarchical control systems. It develops a stepwise evaluation
approach that is applied to the example scenario of a supervisory
controller for supermarket temperature control, addressing
scenarios of variable electricity prices. Based on the structure of
the message exchanges between supervisory and local controllers,
first the impact of deterministic delays on the information age
that is used by the controller to calculate set-points is analyzed.
Subsequently we investigate the impact of communication network
performance on the supermarket refrigeration control and
resulting energy costs using simulation models. The results show
that the controller is resilient to downstream information delays,
however upstream delays or up- and downstream information
loss can cause significant performance decrease.
