This paper investigates a load frequency control issue for multi-area
interconnected unknown power systems with random communication delays.
First, a model-free adaptive control scheme is established by building
an equivalent data relationship model between area control error and
corresponding control input. Then, a dynamic event-triggered scheme is
designed to improve resource utilization and reduce computational
burden. Furthermore, random communication delays in the feedback and
forward channels are considered. The results show that the proposed
method is independent of any model information about the power system,
only using the controlled system's control input and output data.
Several simulation results validate the effectiveness of the proposed
control scheme.
