Research on Integration Model of Shore-to-ship Power Supply System with High Proportion Renewable Energy

The traditional shore to ship power supply system has been unable to meet the demand of high efficiency and high power quality for warships. Combining with renewable energy and energy storage, this paper studies the integration mode of high proportion renewable energy shore-to-ship power supply system, and proposes three system topologies. According to the demand of 50Hz load power supply, the system topology of DVR scheme is more conducive to improving power supply efficiency, and has grid-connected/islanded function. It not only greatly reduces the dependence on Municipal electricity, improves the reliability and automation, but also realizes the demand of energy saving and environmental protection. Combined with DVR scheme, the control strategy based on inductance current band-pass feedback is proposed to further ensure the high power quality of the load.
