摘要:

需求响应(DR)资源参与电网互动丰富了电网调度的手段,然而,由于DR资源的不确定性且个体趋利性难以直接控制,相较于传统电力资源,其交易的违约概率更大,使得结算与惩罚机制复杂化。为有效引导需求侧资源积极参与响应,降低违约风险,从而提高DR参与调度的可用性,提出了基于区块链的DR资源信用管理方法,分别搭建了集中交易和双边交易下考虑信用值的DR资源交易机制,设计交易各阶段的智能合约并部署在以太坊测试链上,探讨在不同信用值下用户的响应效果。算例表明,提出的交易方式有效降低了DR资源的调用成本,守信用户可获得更多利益,从而从长期角度有效引导DR资源参与市场交易,维持DR资源交易市场稳定发展。

Abstract:

The participation of demand response (DR) resources in the interaction of power grids enriches the means of power grid dispatching. However, due to the uncertainty of DR resources and the difficulty of direct control of individual interest, the transaction default probability of DR resources is higher than that of traditional power resources, which complicates the settlement and punishment mechanism. In order to effectively guide the demand-side resources to actively participate in response, a blockchain-based DR resource credit management method is proposed to reduce the risk of default, thereby improving the availability of DR for participating in scheduling. A DR resource transaction mechanism considering credit value in centralized transactions and bilateral transactions is established. And the smart contracts at each stage of the transaction are designed and deployed on the Ethereum test chain to explore the response effects of users under different credit values. The example shows that the proposed transaction method can effectively reduce the cost of DR resources, and the trustworthy users can obtain more benefits, thereby effectively guiding DR resources to participate in market transactions from a long-term perspective and maintaining the stable development of DR resource transaction markets.
