On the basis of analyzing the logical structure of grid information model (GIM), a modeling method of GIM using the set theory is proposed for the substations. By studying the coupling principle of power flow and information flow, the GIM was defined as the interconnection between the set of physical objects and the set of information objects. Then, the GIM was decomposed into the power subsystem and load subsystem, which were described from the aspects of input, output, state changes and network structure. Under the constraints of the existing power grid network, subsystems were connected in accordance with rules from different perspectives to form the complete GIM system.
