Towards Realization of a Control-Commnunication Framework for Interactive Power Networks

Smart grids in near future will be expected to provide high fidelity power-flow control, self healing, and energy surety and energy security anytime and anywhere. This will require a ubiquitous framework of distributed control-communication supported by pervasive computation and sensing technologies. However, effective operation of such an integrated control-communication framework will need i) a "joint" optimization strategy that ensures an optimal balance between performance of the control system under stability bound and the dynamic network capacity of the communication network; and ii) a mechanism for partitioning the functionality to achieve a distributed or pseudo-decentralized implementation. In this paper, some of these issues have been raised and an outine on the first-step approach has been provided along with case studies involving homogeneous inverter network and a scaled microgrid. A novel nodal architecture has been proposed as well to demonstrate a possible approach towards implementation of the control-communication framework.
