The construction of ubiquitous power Internet of Things（UPIoT）can open up a new way for the operation and management, investment and service of power grid. Therefore, according to the development path of UPIoT, the optimal dispatching construction of UPIoT is realized, the efficiency of energy system is improved. Firstly, the optimization subjects and contents of platform layer and perception layer of UPIoT are studied. Secondly, the edge optimization scheduling model of the physical network terminal equipment is constructed. Finally, the typical daily load of a park is introduced and the NSGAII intelligent algorithm is applied in the model, which verifies the feasibility of the model and explores the construction and application methods of UPIoT as a whole.
