Multi-level graph-model integration method and system for electric power system modeling

The invention discloses a multi-level graph-model integration method and system for electric power system modeling, and relates to the technical field of electric power system modeling, and the method comprises the steps: carrying out the multi-level decomposition of an electric power system, carrying out the multi-level component packaging of a hierarchical subsystem, building an internal topological structure, and dynamically generating interface points; connecting identifiers are added, the multi-level components are connected through interface points, a circuit topological graph is formed by adopting self-adaptive topological optimization, and a power system model is output; and performing power system simulation through the power system model and obtaining simulation data, and performing data verification through interaction with each hierarchical model. According to the method, a circuit topological graph is formed and a power system model is output by adopting an adaptive topological optimization techn
