Typical coordination schemes for future power grids require two-way\ncommunications. Since the number of end power-consuming devices is large, the\nbandwidth requirements for such two-way communication schemes may be\nprohibitive. Motivated by this observation, we study distributed coordination\nschemes that require only one-way limited communications. In particular, we\ninvestigate how dual descent distributed optimization algorithm can be employed\nin power networks using one-way communication. In this iterative algorithm,\nsystem coordinators broadcast coordinating (or pricing) signals to the\nusers/devices who update power consumption based on the received signal. Then\nsystem coordinators update the coordinating signals based on the physical\nmeasurement of the aggregate power usage. We provide conditions to guarantee\nthe feasibility of the aggregated power usage at each iteration so as to avoid\nblackout. Furthermore, we prove the convergence of algorithms under these\nconditions, and establish its rate of convergence. We illustrate the\nperformance of our algorithms using numerical simulations. These results show\nthat one-way limited communication may be viable for coordinating/operating the\nfuture smart grids.\n
