摘要 针对在多种交易模式(联营体交易、双边交易、多边交易)共存的电力市场中,如何公平合理地分摊输电网的网损这一问题,给出了一种网损分摊方法。即以电流分解为基础,用电流表示交易,按网损分量分摊法将网损先分摊到交易,然后再对联营体交易(或多边交易)进一步分摊到参与该交易的发电机和负荷,每个输电设备追溯的网损成本一半分配给用它的发电机,一半分配给由它送电的负荷。通过对5节点系统进行算例分析,验证了该方法的正确性和合理性。 A method of loss allocation is presented in electricity market coexisting with different transaction modes such as Pool transaction mode, bilateral transaction mode and multilateral transaction mode. The method is based on the separation of current. Each transaction is described by corresponding current, and the loss that should be borne by each transaction is calculated with the method of loss component allocation. Then, the previously determined loss of Pool transaction mode or multilateral transaction mode is further allocated to all of the generators and loads that take part in the transaction. A half of loss cost of each transmission element is allocated to generators, and the other half is allocated to loads. Analysis of 5-bus system shows that the proposed method is correct and reasonable.
