| 摘要: |
| 伴随电力体制改革的不断深入和分布式能源的大量接入，电力现货交易的商业模式正在被不断探索，亟需提出新的交易机制来适应新的商业模式。首先，基于去中心化的思想设计了一种适用于日内现货市场的分布式电力交易机制，激励产消者根据自身实际发电能力或用电情况发起实时的点对点交易需求，就近与周边产消者用户直接进行交易。然后，应用区块链技术以智能合约的形式规定交易规则，明确产消者的权利与义务。最后，结合智能电表与智能终端搭建具有两层互操作层的分布式电力交易平台，多信息融合通信，支撑交易自动出清与结算。提出的分布式电力交易机制可实现产消者点对点多边竞价交易，鼓励产消者合理申报交易需求，实现能源的高效分配、合理利用。 |

| Abstract: |
| With the deepening of the reformation of power system and the massive access of distributed energy, the business model of electric power spot trading is being investigated. It is urgent to put forward a new trading mechanism to adapt to the new business model. Firstly, a decentralized power transaction mechanism is designed based on the idea of decentralization, which is suitable for the intraday spot market. It encourages prosumers to initiate real-time peer-to-peer trading demand according to their own actual demand of power generation capacity or electricity consumption. Prosumers can trade directly with others nearby. Then, the transaction rules are formulated in the form of smart contracts by applying the blockchain technology to define the rights and obligations of prosumers definitely. Finally, a distributed power trading platform with two interoperable layers is built by combining smart meter and smart terminal, multi-information fusion communication supported automatic clearing and settlement of transactions. The proposed decentralized power transaction mechanism can realize peer-to-peer multilateral bidding transactions among prosumers. It encourages prosumers to declare their trading demands appropriately, so as to achieve efficient distribution and rational utilization of energy resources.
