摘要: |
将分布式可再生能源和互联网技术相结合的“能源互联网”概念为解决人类的化石能源危机提供了可行路径。能源互联网将打破电、气、热等不同能源系统间的壁垒,实现多种能源的综合高效利用,支持大规模可再生能源的广泛接入,成为耦合多能流的开放互联新型能源供应系统。首先基于能源互联网的相关研究,归纳了能源互联网的多能流耦合特征。接着介绍了多能流耦合模型的构建方法,根据能源组网的结构和用能形式的不同,分析了能源互联网的多能流交互机理。在此基础上对能源互联网的优化模型和多能流多时间尺度动态优化方法、以及计及空间尺度的多源互补动态优化方法进行深入剖析,将为能源互联网建设提供理论基础。 |

Abstract: |
The concept of “energy internet” combining distributed renewable energy and internet technology provides a feasible path for solving the fossil energy crisis. The energy internet will break the barriers between different energy systems such as electricity, gas and heat, realize the comprehensive utilization of multiple energy sources, and support the wide-scale access of large-scale renewable energy, open and interconnect multi-energy networks, and become a new energy supply network coupling a multi-energy flow system. This paper first summarizes the multi-energy coupling characteristics of the energy internet based on existing research. Then a construction method for a multi-energy flow coupling model is introduced. In line with the structure of the energy network and the form of energy use, the multi-energy flow interaction mechanism of energy internet is analyzed. On this basis, the optimization model of the energy internet, the multi-time scale dynamic optimization method of multi-energy, and the multi-source complementary dynamic optimization method based on spatial scale are analyzed. This will provide a theoretical basis for energy internet construction.
