考虑源-荷双向灵活的含CCP-LCDR的区域综合能源系统低碳调度优化
Low-Carbon Scheduling Optimization of Regional Integrated Energy Systems with CCP-LCDR Considering Bidirectional Flexibility of Source and Load
摘要
Abstract
[Objective]To reduce carbon emissions in the power system and improve the adoption rate of clean energy with the goal of minimizing total cost,a multi-energy coupling regional integrated energy systems(RIES)collaborative optimization method based on combined heat and power(CHP)with a carbon capture and storage(CCS)power-to-gas(P2G)(CCP)coupling mechanism and low-carbon demand response(LCDR)is proposed.We also introduce a source-load bidirectionally flexible low-carbon scheduling model.[Methods]First,a carbon trading and green certificate mechanism is introduced on the supply side,and a carbon emission allocation model based on the baseline method is established to incentivize the system to consume renewable energy.Secondly,based on the CHP-CCS-P2G multi-energy coupling unit,the energy efficiency of the system can be improved through carbon recycling and energy cascade conversion.Then,the load side introduces a low-carbon demand response mechanism that takes into account differences in load characteristics to establish a bidirectional interaction mechanism between electricity and heat loads based on price elasticity matrices to reduce peak-to-valley load differences.Simulation experiments were conducted using data on electricity consumption from an administrative district in a city in southern China.[Results]The results showed that the carbon emissions and operating costs of the system were reduced using the proposed method,and the wind and solar power consumption capacity of the system was improved.In particular,operating costs were reduced by up to 5.26%compared with the basic scenario.[Conclusions]The proposed method can form a closed-loop conversion of carbon elements to reduce the output of traditional power generation units,increase the grid power of new energy,and achieve"peak shaving and valley filling"through excitation signals.Thus,the proposed approach is designed to reduce carbon emissions and support the transition to a low-carbon economy.关键词
