Modeling and simulation of information-embedded multi-converter power systems

Abstract

Information-embedded multi-converter systems can be found in modern shipboard power systems, dc distribution systems and renewable energy systems. The focus of this work is the incorporation of underlying coupling issues among the converters into their modeling and simulation. This inherent cross-regulation behavior can lead to exceeding controllers' limits, which results in harmful operation situations during system disturbances. Thus the incorporation of these system dynamics into their corresponding modeling formulation is an important feature. This paper addresses the aspects of modeling and simulation of multi-converter based power systems with the inclusion of power electronic equipment dynamics in the overall system model.
