Cognitive Radio Network for the Smart Grid: Experimental System Architecture, Control Algorithms, Security, and Microgrid Testbed

This paper systematically investigates the novel idea of applying the next generation wireless technology, cognitive radio network, for the smart grid. In particular, system architecture, algorithms, and hardware testbed are studied. A microgrid testbed supporting both power flow and information flow is also proposed. Control strategies and security considerations are discussed. Furthermore, the concept of independent component analysis (ICA) in combination with the robust principal component analysis (PCA) technique is employed to recover data from the simultaneous smart meter wireless transmissions in the presence of strong wideband interference. The performance illustrates the gain of bringing the state of the art mathematics to smart grid.

Overview of Communication and Control Techniques in the Microgrid

Microgrid is a distributed power generation system, and is also an effective solution for the connection of grids with high level of distributed energy resources. This paper reviews the microgrid test beds and demonstrated projections in many countries, with emphasis on the communication and control techniques. We arrive at the conclusion that new strategies for communication and control are urgently needed in future power grid.
