Abstract: The development of smart grids faces many problems. The urgent problem is the dispatch of smart grids. To address this, a smart grid economic dispatch model based on a second-order consistency algorithm is proposed. The model transforms dispatch into an unconstrained optimisation problem using convex optimisation theory and integrates a multi-agent consistency algorithm with the internal penalty function method. According to the experimental results, when the training set was 900, the energy saving efficiency of the traditional dispatch model, the dispatch model based on the first-order consistency algorithm, and the second-order consistency algorithm during peak electricity consumption periods were 0.38, 0.55, and 0.64, respectively. During the low power consumption period, when the training set size was 900, the energy saving efficiency of the three models was 0.32, 0.41, and 0.49. The proposed method can effectively solve the power grid dispatch issues, providing a certain reference for relevant research.

Keywords: smart grid; economic dispatch; distributed second-order consistency algorithm; internal penalty function method.
