电力系统正在向分散的模式过渡，通过使用分布式的多种能源，积极的消费者(生产者和消费者)参与进来。本文提出了一种新颖的基于区块链的P2P交易体系结构，通过使用智能合约实现交易过程的自动化、标准化和自我执行，集成了基于协商的拍卖和本地电力市场的定价机制。消费者之间的对等电力交易量和电价的协商被建模为合作博弈，零售商与其消费者群体之间的互动被建模为Stackelberg博弈。住宅供暖系统的灵活性规定被纳入到消费者的能源调度中。实例研究表明，在当地电力市场中提出的架构有助于改善当地的能源平衡。住宅供暖系统的灵活性使消费者能够更好地应对零售电价的变化。与无点对点电力交易的情况相比，该模型使个体消费者或消费者的日均用电成本降低了41.24%。
Electric power systems are transitioning towards a decentralized paradigm with the engagement of active prosumers (both producers and consumers) through using distributed multi-energy sources. This paper proposes a novel Blockchain based peer-to-peer trading architecture which integrates negotiation-based auction and pricing mechanisms in local electricity markets, through automating, standardizing, and self-enforcing trading procedures using smart contracts. The negotiation of the volume and price of the peer-to-peer electricity trading among prosumers is modeled as a cooperative game, and the interaction between a retailer and its ensemble of prosumers is modeled as a Stackelberg game. The flexibility provision from residential heating systems is incorporated into the energy scheduling of prosumers. Case studies demonstrate that the proposed architecture in local electricity markets helps improve local energy balance. Flexibility from the residential heating systems enables prosumers to be more responsive to the variation of retail electricity prices. The proposed model reduces 41.24% of average daily electricity costs for individual prosumers or consumers compared to the case without the peer-to-peer electricity trading.
