Shu Yinbiao , Xie Dian , Zhao Liang , Gao Yajing , Zhao Yong , Zhou Chaoyang

Strategic Study of CAE 2022, Volume 24, Issue 3, Pages 195-204 doi: 10.15302/J-SSCAE-2022.03.020

Abstract: Implementing re-electrification to realize clean substitution at the energy production side and electricIn this article, we analyze the concept of re-electrification and propose to help China achieve low-carbondevelopment with re-electrification considering the basic national conditions and resource endowmentThe development prospect of re-electrification is also proposed.The research results show that re-electrification will significantly promote carbon neutrality.

Current Status and Prospect of the Integration of Railway and New Energy

Hu Tianfei, Liu Jihua,Li Tianfeng,Yue Zurun,Zhang Yimin

Strategic Study of CAE 2023, Volume 25, Issue 2, Pages 122-132 doi: 10.15302/J-SSCAE-2023.02.013

Abstract:

The integration of railway facilities and use of new energies is an important way to achieve the carbon peaking and carbon neutrality goals. After analyzing the demand for the integrated development of railway and new energies, this study summarizes the natural conditions of various new energy sources along railways, including solar, wind, geothermal, acoustic, braking, and vibrational energies. The current integration forms, technical characteristics, and equipment levels are then reviewed. The specific integration scenarios between the railway service facilities, carriers, infrastructures, and new energy sources are summarized by category, and the developmental scales and problems of major scenarios, such as photovoltaic systems at the top of railway stations, new-energy locomotives, and self-power supply monitoring equipment, are discussed. Based on the classification of potentials to supply new energies for railways, a series of new integration scenarios and methods are introduced considering the new energy systems of different scales (e.g., micro, small- and medium-sized, as well as large and super-large). A new major scenario that integrates electricequipment for railway infrastructure defects control and small- and medium-sized distributed off-grid photovoltaic systems is proposed. Furthermore, the future trends, core technologies, and key developmental directions for the integration of railway and new energies are proposed from the aspects such as energy capture and conversion, load, energy storage, and energy management.
