Service-oriented architectures make establishing comprehensive profiles of smart factories feasible. In this paper, an energy tree model is used to describe an overall and detailed profile that shapes energy system dynamics. The model of the energy tree that accumulates local information in real-time, is managed by information-centric industrial networks. Plant-site energy resources that are temporally or spatially related are aligned into groups to relieve ever-changing temporal and spatial misalignments. Meanwhile, energy resources are generalized into process units and energy interconnectors. The key objective of energy tree is to align attributes and to intensify couplings between different process units and energy interconnectors by decomposing and aggregating energy flow. An indoor smart microgrid is set up to testify the model of energy tree, and the electric power input and output were analyzed, which verifies the availability of the energy tree.
