Delay-Aware Control Designs of Wide-Area Power Networks

A co-design of the implementation platform and control strategies for wide-area power networks is addressed. Limited and shared resources among control and non-control applications introduce delays in transmitted messages. The design is based on a delay-aware architecture and cloud computing has been proposed for damping wide-area oscillations. We accommodate possibly large delays in the network and take into account their values in the designs. Moreover, we design output feedbacks for the cases that some state variables are not accessible. The designs are verified through a simulation on 50-bus Australian model.
