Abstract (EN): : The implementation of market mechanisms to remunerate embedded generation should take into account a non-discriminatory access to networks. In consequence, power loss costs must be fairly allocated among the all generators and consumers. In the context of the microeconomic theory, the marginal losses reflect the Short-Term Marginal Costs (STMC) and therefore achieve short-term economic efficiency. Hence, a loss allocation method based in Marginal Loss Coefficients (MLCs) have been proposed in the literature as sensitivity factors measuring the change of total power losses respect the generation/consumption power balance in each node of the system. However, as result of vagueness in demand consumption at given time and stochastic behaviour of renewable sources, MLCs computation is strongly affected by uncertainty in the power injections and load consumption. This paper discusses a new method for computation of active MLCs using Fuzzy Sets to represent distributed power injections uncertainties. The application of fuzzy techniques provides a whole spectrum of feasibility and may be used in the tariff design process. Proposed methodology takes into account the allocation of power losses produced by active and reactive line flows and has been successfully applied to an illustrative three-bus system and a 28-bus distribution test case.
