This paper puts forward the energy management optimization model of commercial buildings under the energy internet, which has the characteristics of multi energy fusion, and considers the coordination strategy of CCHP and energy storage devices under the commercial TOU mechanism. Building comfort and energy expenditure are considered in the optimization objective function. Finally, a simulation of a comprehensive commercial buildings show that the model can effectively meet the needs of building comfort, also can reduce the expenditure of energy costs in commercial buildings; for the algorithm, the grey optimization algorithm obviously has more advantages than the GA and PSO algorithm.
