基于碳绿证市场机制的多区域电力系统低碳调度模型

A low carbon dispatching model for multi regional power systems based on carbon green certificate market mechanism

传统能源资源的有限性和供应安全问题促使人们转向能源互联和低碳电力的研究方向。综合能源系统(IES)逐渐成为实现能源协调和节能减排的关键手段。为了管理碳排放和促进可持续能源的利用,文章提出了一种基于碳绿色证书联合市场的多区域综合能源系统调度模型。监管部门对碳排放量进行分配调整,可分别在碳交易系统和绿证市场系统两个渠道进行交换。评估了在IES中引入碳绿色证书市场机制的可行性,并提出了绿色证书联合市场框架。采用组合双拍卖(CDA)机制进行竞价,确定绿色证书的最佳价格,建立了供热网络和天然气网络的优化模型,并将其与IES的约束相结合,确保系统的稳定运行。该模型分析了碳交易系统、绿证市场系统以及天然气价格的变化对系统运行成本的影响。仿真实验结果表明,该模型能够显著提高IES效益并降低碳排放。

The limited availability and supply security issues of traditional energy resources have prompted people to shift towards research on energy interconnection and low-carbon electricity.Integrated energy systems are gradually becoming a key means to achieve energy coordination and energy conservation and emission reduction.In order to manage carbon emissions and promote the utilization of sustainable energy,this paper proposes a multi regional integrated energy system scheduling model based on the carbon green certificate joint market.Regulatory authorities allocate and adjust carbon emissions,and exchange them through two channels:the carbon trading system and the green certificate market system.This article evaluates the feasibility of introducing a carbon green certificate market mechanism in the Integrated Energy System(IES)and establishes a green certificate joint market framework.This article adopts a combined double auction(CDA)mechanism for bidding to determine the optimal price of green certificates,develops optimization models for heating and natural gas networks,and combines them with the constraints of IES to ensure the stable operation of the system.This article analyzes the impact of changes in carbon trading systems,green certificate market systems,and natural gas prices on system operating costs.The simulation experiment results show that the model can significantly improve the efficiency of the comprehensive energy system and reduce carbon emissions.
