A hierarchical, iterative distributed optimization algorithm is presented. The motivation is the predictive control of a smart grid, in which the states of charge of a network of residential-scale batteries are coordinated so as to minimize variability in the aggregated power supplied to/from the grid by the residential network. The proposed distributed algorithm calls for communication between a central entity and an optimizing agent associated with each battery, but does not require communication between agents. The distributed algorithm is shown to achieve the performance of a large-scale centralized optimization algorithm, but with greatly reduced communication overhead and computational burden. A numerical case study using data from an Australian electricity distribution network is presented to demonstrate the performance of the distributed optimization algorithm.
