| 摘要: |
| 分布式能源发电容量较小，不适合参与传统的电力交易，且其出力的不确定性易造成交易违约。通过区块链技术中的联盟链构建了适合分布式源、荷进行点对点交易的社区型电力交易平台，提出一种委托权威证明(DPoA)共识机制对区块链节点进行信用评价与激励。构造了履约信用函数和验证奖励函数对链上节点的交易履约与交易验证情况进行量化评价，并依据节点信用评价结果建立了信用奖惩激励机制。通过分析10个分布式源、荷节点参与的电力交易过程表明：基于区块链技术构建的社区型电力交易平台，可发挥电力市场促进分布式清洁能源消纳的作用；基于DPoA的信用激励机制可激励分布式电力交易节点提高履约度，维护自身信用。 |

| Abstract: |
| The smaller generating capacity makes the distributed energy unsuitable for participating in traditional power trading, and the output uncertainty often leads to transaction defaults. Based on the consortium blockchain, a community-based electricity transaction platform, which is suitable for P2P(Peer-to-Peer) transactions of distributed sources and loads, is developed, and the DPoA(Delegated Proof of Authority) consensus mechanism is proposed for credit evaluation and incentive of blockchain nodes. The fulfillment function and verification reward function are constructed to quantitatively evaluate the performance and the verification of the transaction, and the function values can be used to establish an incentive mechanism by credit reward or credit punishment. The analysis of the electricity transaction process involving ten distributed source and load nodes shows that the community-based electricity transaction platform based on blockchain technology can promote the consumption of distributed clean energy, and the incentive mechanism based on DPoA can encourage the nodes of the electricity transaction platform to improve the credit initiatively. |
