基于区块链的共享储能联合市场竞价模型与交易机制

随着可再生能源的普及率的不断提高,其固有的不确定性使储能技术在电力系统中的发展成为必然。目前,由于1)储能需求与资源配置不合理,2)缺乏储能共享机制这两点问题,储能的价值仍未完全释放。针对上述局限性,该文设计了一种基于区块链的储能共享机制。首先,文中建立了一个竞价模型,以最优化能源、频率和柔性斜坡产品联合市场中储能设备的投标策略。在此基础上,该文提出了一种基于区块链的点对点(peer-to-peer, P2P)共享储能机制,以实现可信和透明的交易。此外,本文涉及了一种智能合约,自动校验各交易主体提供足量储能服务的能力。最后,在Substrate私有区块链上的仿真结果验证了该机制的有效性。

Energy storage sharing method based on blockchain: model, mechanism and Implementation

With the increasing popularity of renewable energy, its inherent uncertainty makes the development of energy storage technology in power system inevitable. At present, the value of energy storage has not been fully released due to the following two problems: 1) unreasonable allocation of energy storage demands and resources; 2) lack of energy storage sharing mechanism. In view of the above limitations, this paper designs a blockchain-based energy storage sharing mechanism. A bidding model is established to optimize the bidding strategy of energy storage equipment in the joint market of energy, frequency and flexible slope products. On this basis, a peer-to-peer (P2P) sharing energy storage mechanism based on blockchain is proposed to realize trusted and transparent transactions. In addition, this paper involves a smart contract to automatically verify the ability of each trading entity to provide sufficient energy storage services. The simulation results on the Substrate private blockchain verify the effectiveness of the proposed mechanism.
