Research on Improved Marginal Loss Coefficient Approach
The marginal loss coefficient method has been widely applied to loss allocation in the external power market,and proved to be a typical method with good prospect.Based on the scaling method which regulates the total loss,considering the loss caused by excessive recovery and the cognation between allocations and selected balance nodes,this article uses different balance nodes to calculate the loss allocation and takes the average as final allocation,which keeps the total loss allocation consistent with the actual loss and makes loss allocation irrelevant to balance node.Then,take IEEE-14,IEEE-30 bus as examples,compared loss allocation before and after using scaling method as well as selecting different balance nodes,the result shows the accuracy and validity of the improved method.
