The leader election criterion for decentralized economic dispatch using incremental cost consensus algorithm

In a smart grid, effective distributed control algorithms could be embedded in distributed controllers to properly allocate electrical power among connected buses autonomously. By selecting the incremental cost of each generation unit as the consensus variable, the Incremental Cost Consensus (ICC) algorithm is able to solve the conventional centralized economic dispatch problem in a distributed manner. The mathematical formulation of the algorithm is presented in this paper. The results of several case studies are also presented to show that the difference between network topologies will influence the convergence rate of the ICC algorithm.
