Abstract

The restructuring of the electricity industry and the development of the electricity market have resulted in an increasing need for coping with the problem of allocating the cost pertaining to deploying power grids to market participants. One of the important components of network usage charges is the cost of power loss. However, because of the nonlinear relationship between power loss and branch power flow, the power loss allocation in power systems is highly challenging. As a result, current methods for allocating power loss usually do not ensure fairness for power grid users. This paper provides a detailed comparison of three alternative methods associated with power loss allocation, including the procedure using the superposition theorem, the methodology based on a modified distflow model and the marginal loss coefficient algorithm. The calculation results of power loss allocation for the IEEE 33-bus radial distribution grid are deployed with the aim of comparing and evaluating these three methods.
