A load flow and fuzzy linear programming based external network modeling approach

A new external network modeling approach is proposed in this paper. This approach is based on load flow solutions and a fuzzy linear programming formulation. The idea of the proposed method is to find an acceptable solution that matches most closely to the knowledge there is for the external network. Uncertainties of the external network data are modeled by using fuzzy set theory. Test results have shown that the proposed method provides a stable and flexible tool for finding an estimated real-time network solution. Contingency analysis performed on the obtained models has indicated that the external network solutions are acceptable
