Fair allocation of charges based on transmission facility availed by the entities present in the open access system is the need of the hour. In order to achieve transparency and fairness from the point of participants involved, it is necessary to get contributions from each generator (source) to loads, flows in the network and losses for the system. This paper attempts to evaluate real power flow in the lines of the network due to individual sources and its contribution to each load using the virtual flow methodology which is fairly simple and straightforward. The proposed method is compared against two well known tracing techniques adapted from proportional sharing principle. Virtual tracing method involves the network topology, parameters and the voltage gradients between buses as determined from a solved power flow/on-line state estimator. It is believed that this is more realistic in nature. Counter flow components are easily determined and loop flows are handled without any difficulty. Case studies on a sample 5 bus and a practical 11 bus Indian southern grid equivalent 400kV networks are presented.
