摘　　要：为理清在多区域互联系统中各子区域间的混合交易对碳流分布的影响,该文提出了一种计及混合交易模式的多区域互联电力系统碳排放流计算方法。首先采用分裂法的思想,将原多区域互联电力系统转化为直观的双边交易系统。再根据潮流追踪法,将联营交易等效为多笔虚拟双边交易,成功将网损分至每笔交易,实现双边交易网络与联营交易网络的解耦。然后根据每笔交易的特性,得出新交易网络的运行参数,分别计算出各网络中的支路碳流率与负荷碳流率,进而计算出原多区域互联系统的碳流分布。算例结果显示,与传统的碳流计算法相比,上述方法能够反映出不同混合交易模式对系统碳流分布的影响,有效地避免不同交易耦合所造成的“碳泄露”,并能向电力用户展示碳排放的构成信息,具有较高的实用价值。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.
