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.
