The embodiment of the invention provides a cellular power supply network, an intelligent gateway of the network and a power supply control method. The cellular power supply network comprises at least one cellular power supply layer, wherein the cellular power supply layer has a cellular structure connected by a plurality of transformers. Electric energy can be transferred from one transformer to another transformer needing electricity according to the need, so that the electric energy is more reasonably configured, and the energy utilization rate is improved. Due to the technical scheme, whena certain transformer cannot normally work due to a fault, electricity outside the transformer can be introduced into the transformer of a user through the cellular power supply network so as to keepelectricity continuity. Meanwhile, the transformer can be separated from the power supply network to be repaired and maintained.
