Construction of The Evaluation Index System of The Regional Integrated Energy System Compatible With the Hierarchical Structure of the Energy Internet

Energy Internet has become the current international frontier and national demand, and is the key means to achieve cross domain integration and collaborative sharing of energy resources. Regional integrated energy system (RIES) is an important form to tap the complementary capacity of different energy sources and promote energy Internet technology. Energy Internet has a three-tier architecture of energy layer, information layer and value layer. Based on the study of energy conversion mechanism, network interconnection demand, energy efficiency and energy quality efficiency of energy system, the energy conversion path evaluation index for energy layer, the network interworking ability evaluation index for information layer and the comprehensive energy efficiency evaluation index for value layer are designed respectively in this paper, then the evaluation index body of regional comprehensive energy system is founded and verified by an example. The proposed evaluation index system can be used for quantitative analysis of the operation and design of RIES, and guide the relevant research and construction work of investors, design and planning units and system operators.
