Optimal Configuration of Integrated Energy System Considering Storage Temperature Characteristics

Integrated energy system is an energy technology that can utilize energy in multiple stages and realize multiple energy inputs and multiple energy outputs. The characteristics of the pipe network and the heat storage tank have an important impact on the overall performance of the integrated energy system. This paper takes hospital energy consumption as the object, sets economic goals, and uses flow and temperature changes to describe the energy flow characteristics of pipe network, heat storage tank and absorption chiller. And considering the temperature change limit, construct a comprehensive energy system configuration optimization model. By simulating a numerical example, the economics of the integrated energy system, the law of water supply and temperature change of the heat storage tank are studied. The results show that the annual cost of the integrated energy system is reduced by about 27.7% compared with the conventional energy system, and the response and temperature changes of the heat storage tank are in line with reality.
