Shooting-Method-Based Simulink Initialization

This work presents the implementation and performance of a shooting method for rapid initialization of electrical power systems models implemented with the specialized power systems libraries of Simulink. We selected the numerical differen-tiation method as the shooting method since it does not need the mathematical model of the dynamic system explicitly, but only the state vector at the beginning and the end of the fundamental period. Additionally to the initialization, the method provides stability of the solution through the Floquet multipliers. We tested the method with a STATCOM based on a two-level inverter, and the results exhibit its correct performance in accuracy and computation time.
