Fixed-Time Consensue-Based Scheme for Economic Dispatch of Smart Grid

In this paper, we introduce a new economic dispatch strategy to solve the energy management problem in a smart grid which is a distributed and cooperative method. Different from the existing works, this paper aims to achieve the optimization in a settling time. The balance between supply and demand constraint can be kept during the computing time. Then, it is demonstrated that the total cost can reach it’s minimal value in the settling time with initial values satisfied the balance constraint. Finally, we verify the effectiveness of the theoretical result with a numerical simulation.
