Branch resistance is much smaller than branch reactance so that branch susceptance can be approximated by b ij x ij ≈ −1 (C.18) 2. The voltage angle difference between the two buses of a branch is small and therefore sin cos . δ δ δ δ ij i j ij ≈ − ≈1 0 (C.19)

WebThe network equations, in the most general case, are the well known AC Power Flow Equations. An initial feasible steady-state solution of the post-fault system is obtained, using the efficient BPA Power Flow Program. The optimization equations are developed for the case of emergency operation, satisfying the Kuhn and Tucker conditions.
In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as voltages, voltage angles, real power and reactive power. It analyzes the power systems in normal steady-state operation.
