The distributed economic dispatch of smart grid based on deep reinforcement learning

Abstract

In order to solve the problems of inefficient, inflexible and insecure for traditional centralized algorithm in the process of optimization dispatch, and with the application of artificial intelligence technology to smart grids, the novel distributed solution is proposed by using the deep reinforcement learning and the consensus theory to optimize the economic dispatch. Firstly, the optimal commitment sequence of massive units is realized through constructing deep reinforcement learning model. Secondly, the optimal unit output and efficient economic dispatch can be obtained by utilizing the improved consensus algorithm together with Adam's algorithm. Finally, simulation results of IEEE-14 and IEEE-162 node systems may demonstrate the effectiveness of the proposed solution for the smart grids with complex network structures, which can not only solve the problem of massive data processing, but also it may reduce the dependence on the exact objective function when dealing with extremely complex load distribution scenes and distributed powers.
