Abstract :
Design oriented criteria are developed for distributed power systems with constant power loads to guarantee stability during large disturbances. The criteria place design constraints on the input filter parameters, such as the Q factor, and constraints on the amount of “ideal” constant power load that a system can support. The criteria are based on Lyapunov stability theory, mixed potential functions, and the existence of equilibrium points. The analytical criteria are validated by means of computer simulations
