Resumo: The active and reactive power services and transmission losses allocation methods had became an important issue after implantation of power systems new economic model and with open market access to agents (generators and loads) due the increase global power demand. The objective is to solve the problem of power services and transmission losses allocations and finding services beneficiaries as well transmission losses responsibilities to each market agents of a fair and equitable way. The results of the allocation problem are very important to economics evaluations of investments in futures generations and loads units installations. Several allocation methods has been proposed in the specialized technical literature, however due the non-linear characteristic of transmission losses and loads, there isn t an ideal method, and still remains the equity question. This work is intented to propose a method to simultaneously allocations performing active and reactive power service and transmission active and reactive losses. The method is based on circuit laws and superposition principle. The method suggest a modeling of sources and loads as equivalent admitances and taking into account the similarities, based on electric circuits, of power services and transmission losses allocations. The proposed method uses a load flow results and divide network into operation scenarios and generators and loads are modeling as equivalent admittances and the current injections are null and then the network is represented by branches and active and reactive power generated or consumed are determined and allocating among market agents. Finally, analysis, simulations and comparisons with some methods proposed in literature are performed, using four buses test system and IEEE 30 buses.
