Three level time decomposition quasi-static active and reactive power flow control

A three-level time-decomposition quasi-static power-flow control model of power systems is presented. The model enables the simple solution and computation of the primary, secondary and tertiary quasi-static power flow control effects. The active and reactive power flow control characteristics are considered. The model exploits the Newton-Raphson method for the computation of all three control subproblems. Computational efficiency is ensured by the specific application of the inversion matrix lemma and the decoupled model constant coefficient matrices. The developed model is intended for security and emergency analysis/control computations
