A Distributed Approach to Economic Dispatch in Power Systems

This paper proposes a distributed dynamics to solve the economic dispatch problem in electric power systems. The approach can be implemented in a fully decentralized manner and it does not require any central control unit. It is assumed that the participating entities can exchange information over a potentially asymmetric communication network. In particular, when the local generation cost functions are quadratic and the communication network is strongly connected, we establish the exponential convergence of the proposed dynamics to the optimal solution of the dispatch problem. We also provide simulation studies on an IEEE benchmark to demonstrate the performance of the proposed dynamics. Copyright (C) 2022 The Authors.
