作为有望解决人类社会'能源三元悖论'的一种重要手段，端对端能源交易（peer-to-peer energy trading）在近年涌现并快速发展。在端对端能源交易中，分布式能源（distributed energy resource, DER）直接互相进行能源的交易和共享。基于对相关学术论文、研究项目和工程实践的综合调研，本文总结并分析了端对端能源交易的全球发展现状，讨论了端对端能源交易的5个主要方面，包括市场机制设计、交易平台、物理和信息通信基础设施、社会科学视角以及政策法规；针对每个方面，对现有相关研究和实践均进行了批判性分析，并就未来的发展方向做出了展望；文末对主要发现和展望做了系统性总结。端对端能源交易是一个快速发展的领域，为全球的学术界和工业界提供了巨大的潜力和机会。

As a promising solution to address the 'energy trilemma' confronting human society, peer-to-peer (P2P) energy trading has emerged and rapidly developed in recent years. When carrying out P2P energy trading, customers with distributed energy resources (DERs) are able to directly trade and share energy with each other. This paper summarizes and analyzes the global development of P2P energy trading based on a comprehensive review of related academic papers, research projects, and industrial practice. Key aspects in P2P energy trading are identified and discussed, including market design, trading platforms, physical infrastructure and information and communication technology (ICT) infrastructure, social science perspectives, and policy. For each key aspect, existing research and practice are critically reviewed and insights for future development are presented. Comprehensive concluding remarks are provided at the end, summarizing the major findings and perspectives of this paper. P2P energy trading is a growing field with great potential and opportunities for both academia and industry across the world.
