考虑电-碳交易的园区综合能源系统经济运行评估

Economic operation evaluation of park integrated energy system considering electricity-carbon trading

各类园区的二氧化碳排放量约占全国总体碳排放量的30%,低碳高效的园区综合能源系统是实现我国“碳达峰、碳中和”目标的重要途径。文章首先建立了园区综合能源系统的电-碳市场交易架构,分析了园区综合能源系统的碳排放责任;然后综合考虑购能成本和碳排放交易成本,以系统总体运行成本最小为目标,提出考虑电-碳综合效益的园区综合能源系统经济运行评估模型。算例分析表明,文章所提出的经济运行评估模型能充分反映综合能源系统的碳排放成本,证明了间接碳排放成本的引入会增加总体运行成本,更高的碳价和更高的减排目标均可以驱使园区减少碳排放总量,助力实现“双碳”目标。

The carbon dioxide emissions of various parks account for about 30%of China's total carbon emissions.The low-carbon and eficient park integrated energy system is an important way to achieve China's"carbon peak,carbon neutrality"goal.Firstly,this paper establishes the electricity-carbon market trading architecture of the park integrated energy system,and analyses the carbon emission responsibility of the park integrated energy system.Then,considering the energy purchase cost and carbon emssion transaction cost,the economic operation evaluation model of the electricity-carbon benefit of the park integrated energy system is proposed with the goal of minimizing the overall operation cost of the system.The example analysis shows that the economic operation evaluation model proposed in this paper can fully refect the carbon emission cost of the integrated energy system,and proves that the introduction of indirect carbon emission cost will increase the overall operation cost.Higher carbon price and higher emission reduction targets can drive the parks to reduce the total carbon emssion and help achieve the"double carbon"goal.
