Allocation of complex power losses between participants of energy exchange in electrical networks

Due to liberalization of energy market as well as the encouraged bilateral contracts between energy producers and consumers the tasks of loss allocation become more and more important. All transactions between producers and consumers require approaches and methods for definition of power losses proportions caused by each load (consumers) and the final distribution among them. The article describes the task to allocate the losses in distribution networks (35/10/0.4 kV voltage level) to the different loads. A method to distribute losses between consumers is explained. For individual loads the factors of their efficiency related to power losses are determined. The application of the suggested method is demonstrated by a numerical example.
