城市园区微网系统端对端能量交易技术研究现状与展望

State-of-the-art Analysis and Perspectives for Peer-to-peer Energy Trading Technology in Urban Community Microgrid System

随着分布式能源(distributed energy resources,DERs)以及需求侧柔性资源的广泛应用,城市园区微网系统(urban community microgrid system,UCMS)的架构、形态和运行方式将发生根本性改变,终端用户在微网中的身份将从传统的消费者转变为兼具能量生产与消费能力的产消者。通过建立端对端(peer-to-peer,P2P)能量交易机制,各个产消者之间可以在市场的引导下实现能量资源的协调优化,有效提升经济效益、供需平衡以及可再生能源就地消纳等UCMS全局效用。为此,分别从交易机制、运营策略以及建模分析3个角度,对城市园区微网系统P2P能量交易技术的研究现状进行了分析,希望能够对未来UCMS市场化运营提供一定的思考和借鉴。

As massive integration of distributed energy resources(DERs)and demand-side flexible energy resources are extensively applied,the structure,form,and operation mode of the urban community microgrid system(UCMS)will be fundamentally changed.The role of end-users in the UCMS will transform from traditional consumers into prosumers with energy production and consumption capabilities.The coordination and optimization of energy resources among prosumers can be achieved by introducing the peer-to-peer(P2P)energy trading mechanism,promoting the economic benefit,energy self-sufficiency,and renewable energy self-consumption of the UCMS.Therefore,this paper analyzed the existing research of P2P energy trading technology in the UCMS from the perspectives of trading mechanism,operation strategy,and modeling methods,hoping to provide some thinking and references for the market-oriented operation of UCMS in the future.
