Research on Efficiency Evaluation Method for Energy Flow Interface Configuration of Multi-energy Integrated Equipment

This paper proposes a systematic performance evaluation method for the energy flow interface configuration efficiency of multi-energy integrated equipment in the field of road transportation. The method first analyzes the energy flow topology of the multi-energy integrated equipment and, in conjunction with typical energy flow conversion circuits, such as Alternating Current (AC)-Direct Current(DC) Conversion, AC-AC, DC-AC, DC-DC, constructs a detailed energy flow interface model. By applying the Analytic Hierarchy Process (AHP), seven key evaluation indicators are proposed, including energy conversion efficiency, interface stability, compatibility, safety, reliability, maintainability, and flexibility. Furthermore, using the scale judgment matrix and normalization algorithm, the weights of the evaluation indicators are scientifically calculated, ensuring the consistency of the judgment matrix. Additionally, three different energy flow interface configuration schemes are proposed, and the effectiveness of the evaluation method is verified through case studies. The research findings provide theoretical support for the design, optimization, and application of energy flow interfaces in multi-energy integrated equipment, contributing to improved energy utilization efficiency and promoting technological innovation.
