Abstract (EN): Power flow calculations are one of the most important computational tools for planning and operating electric power systems, since they provide information about the state of the system for a specific deterministic scenario of generation and load. After the stabilization of the deterministic power flow calculation methods, the need to capture uncertainty in load definition lead first to the development of probabilistic models, and later to fuzzy approaches able to deal with qualitative declarations and other non-probabilistic information about the value of the loads. In this framework, fuzzy power flow calculations use typically incremental techniques, in order to obtain a good approximation of the fuzzy state variables. However, these models and procedures are not entirely satisfactory for the evaluation of the adequacy of the electric transmission system, since they are not completely symmetric, due to the presence of a slack bus. In this paper, we show how to perform the detailed calculation of the state variables of the FPF problem in an exact and symmetrical way, by means of solving multiple optimization problems. The extension to the constrained fuzzy power flow problem is also described, along with numerical adequacy indices. The procedure is illustrated using the IEEE-14 test system.
