摘要:
      随着大量分布式能源接入配电网,电力系统的安全稳定经济运行进一步受到挑战。可交易能源被视为有望促进系统供需平衡的机制而得到各国学者的广泛关注。综合分布式能源现有技术的发展,将可交易能源机制限定在配电网层面,面向终端用户、电源、储能等分布式主体。在该机制下,分布式主体可直接交易互动,形成去中心化的扁平交易体系,能够通过实时电价引导交易,实现成员收益和系统整体利益的激励相容。首先阐述了面向分布式主体可交易能源系统的概念、特性和意义。进而系统全面地设计了可交易能源系统的体系架构和交易机制,呈现了可交易能源系统具体的运行方式,并分析了相关主体的效益。最后,从系统运行要求出发简述了关键技术,如智能决策系统、区块链等。
Abstract:
      Power systems are now facing challenges in terms of safety, stability and economic efficiency with penetration of a great number of distributed resources(DRs). Transactive energy(TE)has become a hot research area for its promises on supply-demand balance. Considering the current development of DR, the TE is limited to distributed systems when facing the distributed agents such as end-users, DR, and distributed storage. In our mechanism, the distributed agents can communicate and trade directly with each other which form a decentralized and flat trading system. Such transactions feature spot electricity prices so that the interests of members and the system are incentive compatible. Firstly the TE's concept is elaborated and its characters and significance are listed. Secondly TE's architecture and trading mechanism are designed comprehensively. Then, TE's operational process is presented and the benefits of all related members are discussed. Finally the key technologies for TE, such as the intelligent decision system and block chain, are briefly described from the perspective of system operation requirement.
