The method is based on Nesterov’s accelerated gradient approach and works over stochastically time-varying communication networks. We consider the standard assumptions of Nesterov’s method and show that the sequence of the expected dual values converge toward the optimal value with the rate of O(1/k²). Furthermore, we provide a simulation study of solving an optimal power flow problem with a well-known benchmark case.Peer ReviewedPostprint (author's final draft) http://creativecommons.org/licenses/by-nc-nd/3.0/es/ Open Access Attribution-NonCommercial-NoDerivs 3.0 Spain Àrees temàtiques de la UPC::Informàtica Stochastic processes Data transmission systems Multi-agent optimization Distributed method Accelerated gradient method Distributed optimal power flow problem Processos estocàstics Dades -- Transmissió Accelerated Multi-agent optimization method over stochastic networks Conference report
