考虑氢能多元化利用的综合能源系统低碳经济调度
Low-Carbon Economic Scheduling of Integrated Energy System Considering Diversified Utilization of Hydrogen Energy
摘要
Abstract
[Objectives]In the context of"dual-carbon"goals,achieving low-carbon economic operation of integrated energy system(IES)is of paramount importance.However,existing IES models incorporating power-to-gas(P2G)technology often overlook energy losses during hydrogen production.To address this issue,this study proposes a day-ahead low-carbon economic scheduling model for an IES that considers diversified utilization of hydrogen energy.[Methods]First,a mathematical model of a cross-regional IES is established,with carbon capture power plants and P2G as the main energy coupling technologies.Second,given the clean and efficient nature of hydrogen energy,mathematical models are developed for hydrogen-blended combined heat and power generation,P2G systems,hydrogen fuel cells,and hydrogen storage tanks.To avoid energy waste,a heat recovery device is integrated into the two-stage conversion process of P2G.Third,a mathematical model for demand response and green certificate-carbon trading mechanism is established and incorporated into the system's low-carbon economic scheduling strategy.Finally,the optimization objective is set to minimize the total cost,including expenses on green certificate trading,carbon trading,coal-fired power generation,electricity procurement,and natural gas purchases.[Results]The proposed model reduces the total system cost by 55%and achieves the full utilization of wind power.[Conclusions]This scheduling model effectively mitigates energy losses during system operation and significantly enhances the low-carbon economic efficiency of IES.关键词
