The research on the index system of extended energy efficiency evaluation

Multi‐scenario comprehensive benefit evaluation model of a multi‐energy micro‐grid based on the matter‐element extension model

“…Song et al, 19 using five aspects (the index, cascade utilization of energy efficiency indicators, economic indicators, reliability index, and environmental index), built the pluripotent distributed energy sources system with a complementary comprehensive evaluation index system, but the index is too simple in terms of the definition of some indexes and the traditional power system evaluation index, and it lacks cohesion. Tian et al 20 put forward the concepts of the extended system, global system, transmission extended system, and local extended system, and analyzed the relationship between energy consumption ratio and energy utilization efficiency using two energy efficiency evaluation indexes. Wei et al 21 proposed an energy efficiency evaluation index system based on DPSR in combination with a real business situation.…”

“…They proposed the matter‐element extension model for comprehensive evaluation, but its project investment evaluation index is too simple and lacks certain vital elements related to energy such as energy efficiency indexes. Table 1 summarizes the main differences between this paper and the state of the art 17‐27 . In this table, symbols “√” and “×” respectively indicate whether a particular aspect is considered or not.…”
