Information-embedded multi-converter shipboard power systems are comprised of multiple independently operated converters that work together with electromechanical equipment. Their relations can produce a large variety of dynamic and static interactions that can lead to irregular behavior of a converter, a group of converters or the whole system. This inherent cross-regulation behavior may correspond to controller limit violations, which results in harmful operational situations during system disturbances. It is significant then to monitor the system during perturbations; their underlying dynamics exhibit trajectories that not only depend on their independent operation modes. Appropriate modeling is a key issue to power system analysis and warrants primary investigation. This paper addresses aspects of modeling and simulation of multi-converter based shipboard power systems with the inclusion of power electronic equipment dynamics and network control in the overall system model. The model behavior is evaluated with respect to changes in loading conditions and control parameters (local and network) and validated through simulation of a nonlinear observability formulation of the developed system model.
