Novel Reliability Evaluation Method for Urban Energy Internet

With a variety of clean energy sources is connected to the power grid on a large scale, a new type of integrated energy utilization and trading method - Urban Energy Internet was proposed. It can solve the problems of insufficient utilization of clean energy, difficulty in multi-energy coordination, low efficiency of comprehensive energy utilization, difficulty in market transaction in urban energy system, etc. In this paper, the evaluation index system of the urban EI is constructed based on the core indicators, such as energy utilization, conversion efficiency, clean energy proportion, transaction subject participation and information support network reliability. Furthermore, the comprehensive evaluation method of EI is proposed with the integration of analytic hierarchy process (AHP) and Fuzzy analysis. Finally, an example is given to verify the perfection of the index system and the effectiveness of the proposed evaluation method.
