摘要(Abstract)：

随着新型电力系统的发展，需求侧出现了大量灵活负荷，使得电力用户由消费者向产消者转型。产消者能够将其灵活调控能力作为商品参与市场化交易，而海量产消者的涌入势必对市场运营机构带来极大的压力。为此提出分布式交易机制以适应点多量小的需求侧电能互动，并根据不同的互动场景分别设计了弱中心化交易模式和完全分布式交易模式。其中，弱中心化交易模式利用区块链网络和智能合约取代交易中心职能，并基于拉格朗日对偶分解算法迭代完成市场出清；完全分布式交易模式利用一致性协议在产消者间传递价格信号，将市场出清转化为产消者间关于价值的认同。算例分析表明，所提分布式交易机制打破了产消者间的信息壁垒，降低了交易成本，提高了可再生能源消纳率，实现了电力资源的优化配置。
With the development of new power system,there arise a large number of flexible loads on the demand side,making the power users become prosumers. Prosumers can take their flexible regulation ability as commodities to participate in market-oriented transactions,and their pouring into power market is bound to bring tremendous pressure to market operating institutions. Therefore,a distributed trading mechanism is proposed to adapt to the demand-side power interactions at various points in small numbers. According to different interaction scenarios,a weak centralized trading mode and a fully distributed trading mode are designed,respectively. In the weak centralized trading mode,blockchain network and smart contract are used to replace the functions of the trading center,and the market clearing is completed iteratively based on Lagrange dual decomposition algorithm. The fully distributed trading mode uses the consistency protocol to transmit the price signal among prosumers and transforms the market clearing into the recognition of value among prosumers. The example analysis shows that the proposed distributed trading mechanism eradicates s the information barriers among prosumers,reduces the transaction cost,improves the consumption rate of renewables,and realizes the optimal allocation of power resources.
