Active stabilization of line-regulating converters with constant power loads

A control design procedure is described for line-regulating converters in dc microgrids and distribution systems with constant power loads. The controller is stabilized using the backpropagation through time algorithm with truncated state trajectories. A method of model discretization based on 4th order Runge-Kutta numerical integration is used to convert the nonlinear converter model into a representation the meets the requirements of the training algorithm. Simulation experiments are performed to demonstrate the controller performance in a variety of ideal and nonideal conditions.
