Benefit Evaluation Indicators and Methods for Regional Energy Internet

The regional energy Internet is coupled with natural gas, hot and cold, transportation and other technologies complement with the power system as the core. That helps multi-energy advantages complement each other and makes the entire system green and efficient. It is of great significance to promote the transformation of energy structure and promote China's energy revolution. The extraction of key indicators of different aspects of regional energy Internet, and the research of comprehensive benefit evaluation is an important issue that needs to be solved urgently. Firstly, considering the regional energy Internet economic benefits, environmental benefits, social benefits, the indicators with universal adaptability are extracted from the energy link, equipment link, distribution network link and user link. Then the analytic hierarchy process is used to determine the weight of the indictors, and the comprehensive state of the regional energy Internet is obtained by the fuzzy mathematics theory and the improved evidence reasoning. Finally, the effectiveness and practicability of the proposed method are verified by practical examples, and the development level of regional energy Internet in the example is accurately evaluated. Corresponding suggestions for the development of China's regional energy Internet are provided.
