| 摘要: |
| 负荷密集的商业园区、工业产业园区通常以合同形式对入驻企业进行电力资源分配，但是该方法存在配置效率低、资源利用不充分等问题。为此，提出了一种基于区块链的园区级多边用电权交易机制。包含双向拍卖规则和端对端交易的用电权益交易模型充分调动了园区的闲置电力容量，通过市场化手段优化用电权配置，避免了园区外线扩容改造的同时解决了企业临时增容需求问题。在此基础上，基于以太坊私有链的用电权交易机制确保了多边交易过程的公开透明，采用智能合约函数自动执行交易，提高了撮合效率的同时减少了交易成本。通过仿真算例验证了所提交易机制及区块链交易平台的有效性。 |

| Abstract: |
| Commercial and industrial parks with intensive load usually allocate power resources to enterprises in the form of contract, which has some problems such as low allocation efficiency, insufficient resource utilization, and so on. Therefore, a park-level multilateral PUQ(Power Usage Quota) trading mechanism based on blockchain is proposed. The PUQ trading model including double auction rules and P2P(Peer-to-Peer) trading, fully mobilizes the idle power capacity in the park and optimizes the allocation of PUQs through market-oriented means, which avoids the expansion and reconstruction of the park and solves the problem of meeting enterprises’ temporary demand in capacity increase. On this basis, the PUQ trading mechanism based on the Ethereum private chain ensures the openness and transparency of multilateral trading process, and the smart contract function is adopted to automatically execute the trading, which improves the matching efficiency and reduces the trading cost. The effectiveness of the proposed trading mechanism and blockchain trading platform is verified by a simulation example. |
