Functional Analysis of the Integrated Energy Consumption Unit IECU

In order to promote the construction of a new energy system and the low-carbon transformation of the power system, Academician Zhou Xiaoxin has innovatively proposed the layout of an integrated energy production unit (IEPU) based on production bases on the energy supply side, and the construction of an integrated energy consumption unit (IECU) based on end- consumption scenarios on the energy demand side. This paper focuses on IECU, aiming to explore its conceptual connotation and functional model. First, the core connotation of IECU is elaborated in detail. Secondly, the relationship between IECU and integrated energy system (IES) is analyzed, and IECU is divided into layers. Finally, based on the functional analysis method of TRIZ theory, the functional model of IECU is constructed from three aspects, namely, component analysis, structural analysis and functional correlation analysis, and the functional characteristics of IECU are summarized. The research in this paper expects to provide a reference for the construction and development of IECU.
