| description | As an important physical carrier of energy internet, an integrated energy system is of great significance for improving regional comprehensive energy efficiency, ensuring energy safety and realizing energy conservation and emission reduction. In this paper, a staged collaborative planning model of the park-type integrated energy system is built on the basis of the whole life cycle. Firstly, regarding the continuation of equipment installation capacity, the equipment is divided into discrete and continuous groups, and their configuration and operation constraints are refined and unified respectively. Then, with the whole project cycle as the optimization time scale, the relationship between the equipment installation year and the current remaining life is modeled by introducing the equipment selection and operation decision variables. Finally, considering the influence of economic factors such as nominal interest rates and inflation rates, an objective function, involving investment costs, operating costs, and equipment residual value income, is constructed, with the optimal economical performance as the goal. The mixed integer linear programming technique is used to solve the model. The test results of the four scenarios show that the staged collaborative planning considering equipment replacement can cut the equipment investment by 14.76% compared to the traditional single-stage planning. After the introduction of heat storage devices and heat abandonment constraints, the operating cost of the thermoelectric coupled system can be further reduced by 11.78%. |
