1. A method implemented by a gateway node, wherein the method comprises:
obtaining a first data transmission parameter between a first-level node and each node in a first node set, wherein the first data transmission parameter comprises a data transmission distance or a data transmission time, wherein the first-level node is located on a first-level power distribution device in a power distribution grid, wherein the first node set comprises a first node located on a first power distribution device at another level in the power distribution grid other than the first-level power distribution device, and wherein the first node is a first child node of the first-level node;
determining, from the first node set and based on the first data transmission parameter, a second-level node directly coupled to the first-level node; and
generating a physical network topology of the power distribution grid,
wherein the physical network topology comprises a first connection relationship between the first-level power distribution device and a second-level power distribution device on which the second-level node is located.
