Research on Benefit Evaluation Method of User Side Distributed Energy Storage System

Abstract

[Objective] Energy Internet is a complex system that optimizes energy efficiency, load and power grids to achieve optimal energy efficiency. The evaluation index system and comprehensive evaluation of planning schemes are key issues that must be solved in the park′s energy internet planning. [Method] Based on the role of energy internet, an evaluation index system for energy internet planning was conducted and the definition and calculation method of each index in the system was performed. Furthermore, a quantitatively evaluates method based on the analytic hierarchy process was proposed in this paper and the application of the indicator system and evaluation method was analyzed. [Results] By the method proposed, a more quantitative and objective comprehensive benefit assessment can be conducted for energy Internet projects in various parks. [Conclusions] The analysis of the example shows that the proposed method is accurate and effective, which provides method support for project investment operation mode and technical solution decision-making.
