Abstract

Next generation of shipboard microgrids should be adaptable with different types of power sources to address a solution for the growing demand of energy, rising energy prices and environmental pollution reduction. In addition, they should supply complicated power consumers. To achieve these purposes, there is an increasing focus on integration of Alternative Power Sources (APSs) and Energy Storage Systems (ESSs) for future modern ships. These efforts have led to more complex Shipboard Power Systems (SPS) than traditional alternatives. Moreover, SPSs may operate in various operating states. Hence, exact evaluation of system dynamic behaviors has become a major concern and require an effective simulation-based modeling. This paper developed modeling and simulation of All-Electric Ship (AES) based on Medium Voltage Direct Current (MVDC) power system using APSs and ESSs in order to investigate the dynamic performance of Next-Generation MVDC-SPS. The proposed simulation-based Model has been studied in different operational modes consist of normal, alert, emergency and restorative states in MATLAB/Simulink tool. The obtained results verify the model performance.
