Calculation Method of Carbon Emission Flow in Multi-regional Interconnected Power System Considering Hybrid Trading Mode
To clarify the influence of hybrid transactions among sub-regions on the carbon flow distribution in multi-region interconnected power systems,this paper proposed a calculation method of carbon emission flow in multi-regional interconnected power systems with the hybrid trading model.Firstly,the split method is adopted to transform the original multi-region interconnected power system into an intuitive bilateral trading system.Then,according to the trend tracking method,the joint transaction is equivalent to multiple virtual bilateral transactions,the network loss is divided into each transaction successfully,and the bilateral transaction network and the joint transaction network are decoupled.Then,according to the characteristics of each transaction,the operating parameters of the new transaction network are obtained.The branch and load carbon flow rates in each network are calculated,respectively.Then,the carbon flow distribution of the original multi-regional interconnection system is calculated.The example results show that compared with the traditional carbon flow calculation method,the above method can reflect the influence of different hybrid trading modes on the carbon flow distribution of the system,effectively avoid the"carbon leakage"caused by different transaction coupling,and can show the carbon emission composition information to power users,which has high practical value.
