Abstract (EN): The Optimal Power Flow (OPF) problem has been stated traditionally to optimize the electrical power system operation regarding minimal cost criteria. In the scope of the implementation of market mechanisms in supply and demand side, OPF analysis becomes in a useful tool to determine location marginal prices in order to send efficient economic signals to all market agents. Marginal pricing allows the allocation of power losses and congestion in the transmission network. In this scenario, production costs and elastic response of demand are uncertain. The model proposed in this paper uses Fuzzy Sets to represent demand and supply cost functions to deal with OPF problem. Membership functions are obtained related to optimum production strategies and consumption profiles. Fuzzy marginal prices are derived from economic interpretation of dual variables of the problem. The model has been tested for illustration proposes in a simply test case.
