摘要

针对现有需求响应能力仅局限于电力负荷，其到碳排表征仍存中间变量且一致性效果差，造成用户侧降碳作用未能完全发现，因此提出一种考虑负荷低碳响应能力的多区互联电力系统低碳经济调度。首先，建立用户侧低碳能用引导信号用于量化用户侧低碳调节作用。然后，面向多区互联系统，构建计及负荷低碳响应能力的双层优化模型。其中，上层为基于纳什谈判理论的多区系统合作博弈模型，旨在保障各区主体收益独立基础上实现系统风光消纳整体平衡；下层为以耦合碳排放因子为低碳引导的用户侧低碳需求响应模型，旨在促进区域内源荷间低碳互动能力。最后，通过能碳贡献因子实现不同主体的利益公平分配，进而保障市场环境下的所建模型公平合理性。算例结果表明：较传统基于电力需求响应驱动的多区互联系统低碳经济调度方法，所提模型能进一步挖掘用户侧低碳潜力，有效降低系统碳排放量，同时可一定程度上降低系统运行成本，且保证各主体利益分配的合理性。

Abstract

Current demand response capabilities are limited to electrical loads

with intermediate variables existing in carbon emission characterization and poor consistency in calculation results. This leads to the incomplete exploitation of the carbon reduction potential on the user side. To address this issue

this paper proposes a low-carbon economic dispatch strategy for multi-region interconnected power systems that accounts for the load low-carbon response capability. First

a user-side low-carbon energy-use incentive signal is established to quantify the user-side low-carbon regulation effect. Second

a bi-level optimization model incorporating load low-carbon response capability is constructed for multi-region interconnected systems. The upper-level model is a cooperative game model based on the Nash bargaining theory

aiming to achieve the overall balance of wind and solar energy accommodation while ensuring the independent revenue of each regional entity. The lower-level model is a user-side low-carbon demand response model guided by coupling carbon emission factors

which is designed to enhance the low-carbon interaction between internal sources and loads in each region. Finally

a carbon-energy contribution factor is introduced to realize the fair distribution of benefits among different entities

thus ensuring the fairness and rationality of the proposed model under the market environment. Case study results show that

compared with the traditional low-carbon economic dispatch method for multi-region interconnected systems driven by electrical demand response

the proposed model can further tap the user-side low-carbon potential

effectively reduce the system carbon emissions

decrease the system operation cost to a certain extent

and guarantee the rationality of benefit distribution among all entities.
