Abstract

Medium voltage direct-current based integrated power system is projected as one of the solutions for powering the all-electric ship. It faces significant challenges for accurately energizing advanced loads, especially the pulsed power load, which can be rail gun, high power radar, and other state of art equipment. Energy storage based on supercapacitors is proposed as a technique for buffering the direct impact of pulsed power load on the power systems. However, the high magnitude of charging current of the energy storage can pose as a disturbance to both distribution and generation systems. This paper presents a fast switching device based real time control system that can achieve a desired balance between maintaining the required power quality and fast charging the energy storage in required time. Test results are shown to verify the performance of the proposed control algorithm.
