Transmission losses have a considerable effect on the active power generation cost and thus, a strategy to allocate them fairly among the power system agents is essential to economic efficiency of the electric energy market. The present work focuses on the allocation of the active power transmission losses among the buses of a power system operating under pool condition. Three types of approaches, based on extensions of the conventional and optimal solutions of the power network equations, are analyzed here: (1) direct use of sensitivity relationships between the transmission losses and the bus power injections; (2) use of participation factors obtained from power flow solutions; and (3) integration of sensitivity relationships mentioned in the previous item. Numerical results obtained with a 19-bus power network are used to illustrate the main aspects of the loss allocations based on the application of the selected techniques.
