Fuzzy power flow solutions with reactive limits and multiple uncertainties

Importance of simultaneous modeling of diverse sources of non-statistical uncertainty in power system analysis and optimization is being increasingly realized. Keeping this in view, an attempt is made to obtain fuzzy power flow solution considering reactive power limit violations at voltage controlled buses, uncertainties in voltage-dependent load models, load forecast and system parameters. Corresponding to the given range of uncertain variables, a range of dependent variables and functions is provided by the proposed approach. Results of two sample test systems demonstrate utility of this approach. (C) 2005 Elsevier B.V. All rights reserved.
