Joint optimization of control performance and network resource utilization in homogeneous power networks

We describe a joint control-communication optimization framework for network control of interactive power-electronic networks. The optimization framework includes two coupled blocks that in general do not operate cooperatively, one whose focus is on ensuring that the power network operates within its stability and performance bounds and the other, whose thrust is on optimizing the information flow in a communication network. Centralized and distributed implementation approaches for the joint-optimization framework are investigated. A case illustration of a homogeneous power network is provided to demonstrate the efficacy of the joint control-communication framework and comment on the implementation issues.
