摘 要:针对传统电力系统调度中存在的能源结构单一、运行成本高和环保性差等问题,提出了多链式区块链
下计及多类型柔性负荷的电力系统低碳经济调度策略。首先,结合需求侧柔性负荷可平移、可转移和可削减
的特性,建立了计及柔性负荷的新型电力系统框架,实现了更灵活的需求响应;其次,利用能多链式区块链技
术,对碳配额(CEQ)交易数据进行精细化管理,保证了数据的安全性;接着,综合考虑运行成本和 CEQ 交易
成本,构建了总成本最低的电力系统低碳经济调度模型;在此基础上,通过场景对比分析了柔性负荷和 CEQ
交易因素对电力系统调度的影响。仿真结果表明,提出的调度策略能够兼顾经济与环境效益,并有效提升
CEQ 交易效率,为新型电力系统的低碳化转型提供了理论支撑和决策支持。

Abstract:Addressing the issues of single energy structure, high operating costs and poor environmental perfor⁃
mance in traditional power system dispatch, this paper proposes a low-carbon economic dispatch strategy for
power systems considering multiple types of flexible loads under a multi-chain blockchain framework. Firstly, le⁃
veraging the characteristics of demand-side flexible loads that can be shifted, transferred and reduced, a novel
power system framework incorporating flexible loads is established to achieve more flexible demand response.
Secondly, utilizing multi-chain blockchain technology, the paper manages carbon quota (CEQ) trading data with
refined precision to ensure data security. Furthermore, by comprehensively considering operating costs and CEQ
trading costs, the paper constructs a low-cost model for economic dispatch in power systems aimed at achieving
carbon reduction. Based on this, scenario-based comparative analysis evaluates the impact of flexible loads and
CEQ trading factors on power system dispatch. Simulation results demonstrate that the proposed dispatch strategy
balances economic and environmental benefits, enhances CEQ trading efficiency, and provides theoretical and
decision-making support for the low-carbon transformation of new power systems.
