摘要

Multi-energy complementary distributed energy system (MECDES) is an important development direction for the energy system. It has the advantages of energy conservation and environmental protection and has great potential to realize efficient energy cascade utilization through the energy conversion and utilization of cooling, heating, and power in place, achieving a user-oriented energy supply. The present study thoroughly reviews the current research status and puts forward the key scientific issues that urgently need to be resolved by investigating the problems and challenges of the MECDES from the perspectives of the characterization of the energetic mass-energy potential, the synergistic transformation and energy-potential coupling mechanism of multi-energy complementation, energy quality improvement and storage, and proactive regulation of the MECDES. Furthermore, the latest research progress of the MECDES for trickling the key scientific issues is comprehensively presented by proposing the distributed energy system with the complementation of multi-energy sources, developing novel ways of the energy potential coupling and energy cascaded comprehensive utilization of multi-energy complementation, proposing a new theory of multi-energy complementation and energy potential coupling and a new mechanism of source complementation, processing matching and thermodynamic cycle system collaborative conversion of both the fossil energy and renewable energy, and developing a new method of proactive adjust and control for adapting to fluctuating energy input and various energy load demands. Finally, the prospects and recommendations for the future research and development direction of MECDES are provided.
