Abstract:

We consider distributed optimization by a collection of nodes, each having knowledge of its own convex objective function. Information exchange among the nodes occurs over a communication network described by a directed graph. The goal of the whole network is to minimize the sum of the objective functions. We consider the case where the communication networks may be subject to link failures with certain probability. We develop a robustified distributed optimization algorithm. Under the assumption that the undergoing network is strongly connected and the probability of link failure is strictly less than one, we show that the robustified algorithm is able to solve the distributed optimization problem in the sense that the algorithm converges to an optimal solution almost surely. In case study, we will apply the proposed algorithm to distributed energy resources (DER) coordination problem for power grids, where the goal is to minimize the total generation cost while meeting total demand and satisfying individual generator output limit.
