Distributed Economic Dispatch over Strongly Connected Communication Networks

This paper investigates the distributed economic dispatch problem in electric power systems. We propose a distributed algorithm to solve the economic dispatch problem over potentially asymmetric communication networks, without using any central control unit. In particular, the proposed algorithm is shown to converge to the optimal dispatch if the generation costs are convex and the underlying communication network is strongly connected. Simulations on the benchmark IEEE 14-bus system are used to validate the theoretical claims, and to illustrate the performance of the proposed algorithm.
