Reasonable and optimal configuration in the early stage of the construction of an integrated energy system is the key to its good operation,and the practicability and feasibility of the optimization scheme can ensure its proper implementation.Considering that the engineering equipment performance and price showed the characteristics of discrete and nonlinear distribution,it was proposed an optimal configuration method of integrated energy system considering engineering practicability.First,based on the characteristics of energy conversion/storage equipment,the system equipment model was constructed.Then,considering the attribute property of the engineering equipment,the large-scale mixed integer linear programming model was established with the net present value as the optimization objective.Finally,based on a numerical example,the optimal configuration results were compared and analyzed,and the sensitivity of operation and investment was analyzed,which verified the rationality and engineering practicability of the optimal configuration scheme.The numerical example showed that the research method ensured the accuracy of the optimal configuration results,made the optimal product portfolio from the engineering products,improved the practicability of the optimization results,and the economic benefits were more sensitive to the total investment.
