Computationally efficient event-based simulation of switched power systems and AC machinery

摘要

Switched power systems are inherently difficult to simulate, due to the significant sensitivity of the simulation algorithm to the timing of the switching events as well as the potentially complex dynamics of the components. Numerical simulation techniques, while flexible, are not well suited for large time scale simulation of such systems. Methods for increasing the accuracy of numerical simulation techniques increase the computational complexity of the solution, resulting in an obstacle for adoption into time-sensitive applications such as model-based design optimization and hardware-in-the-loop simulation. This paper presents a method and development framework for a computationally efficient method for analyzing the behavior of switched power systems via piece-wise analytical solutions to differential equations. Enhancements of the method to expand the utility are also presented.
