At present, the short-circuit ratio constraint of multi-station is incorporated into the new energy operation limit check by offline calculation, without considering the influence of new energy power distribution and topological structure on the short-circuit ratio. To solve this problem and implement the online calculation, this paper introduces a new graph neural network framework, called the online short-circuit ratio calculation method of new energy multi-station based on message passing GCNConv. Based on the accuracy guarantee, this method can process the graph structure data of the power system, and through the message passing mechanism, the information of nodes and edges can be efficiently aggregated and disseminated, and the real-time online calculation efficiency can be improved. Finally, the performance of the model is verified by the simulation and comparative analysis of the 109-node system.
