发电权交易使得电网的潮流以及损耗发生变化，对电网的运行成本产生影响，因此如何有效计及这种影响并对电网进行相应的补偿是亟待解决的问题。为解决此问题，首先针对断面网损进行研究，在断面下将输电网等效为线性电路，发电机和负荷等效为电流源，通过叠加原理确定各支路潮流及功率损耗与各电流源的关系式，进而确定发电权交易量与网损变化量的关系式。其次，将网损分摊看作一个合作博弈问题，即网损是由所有参与者共同合作的结果。应用Aumann-Shapley法对支路的互耦合功率损耗进行分摊，可保证结果公平合理，且具有经济一致性。最后，通过IEEE9节点标准算例进行仿真，验证了所提方法的正确性和有效性。

Generation rights trade will change the power flow of the grid as well as losses, and then affect the transmission service costs of the grid. Therefore how to take such influence into account effectively and make the corresponding compensation to power grid are the problems to be solved. Firstly, this paper studies the losses allocation method for the section network. A cross-section grid network is equivalent to a linear circuit. Generators and loads are modelled as current sources and the relationship between current sources and branch losses is then established based on the superposition principle. Based on the first step, the relationship between the quantities of generation rights trade and the variations in losses of the network is established. Moreover, losses allocation can be seen as a cooperative game problem that investigates the allocation of surplus obtained by agents of a coalition through cooperation. The Aumann-Shapley is used to allocate the losses and provide fair and reasonable allocation with good economic coherence. Finally, illustrative numerical results with the IEEE 9-bus test system is presented to prove the validity.
