基于智能合约与可交易能源控制的风电消纳辅助决策技术

Decision-Making Support Based on Smart Contracts and Transactive Energy Control in Wind Power Accommodation

随着风电装机容量的不断增长,风电消纳一直是电网运行的关键课题。基于近期学术界广泛关注的可交易能源(transactive energy,TE)系统的理念,文章提出了通过可交易能源控制(transactive energy control,TEC),以一系列交易合约作为控制手段实现风电消纳的技术框架。进一步将智能合约技术与可交易能源控制结合,由各交易方提出各自的交易逻辑,通过智能交易辅助决策形成一系列智能合约,从而实现风电消纳的控制目标。基于IEEE-30节点系统的算例验证了该控制方式的有效性。

With the continuous growth of the installed capacity of wind power,the wind power accommodation becomes a key factor in power gird operation.According to the concept of the transactive energy systems which has been widely investigated in academic area,this paper proposes a framework of wind power utilization by using a series of trade contracts based on transactive energy control(TEC)method.Furthermore,the smart contract technology with TEC is jointly considered in this paper.The trade logics proposed by participants are formulated to a series of smart contracts through the assisted smart-trade decision-making method,and finally the control objective of wind power utilization is achieved.The IEEE 30-node system is used to verify the effectiveness of the proposed control method.
