Abstract

Marine power systems are isolated from external grids, making them more vulnerable than land-based power system. Additionally, different from fixed terrestrial microgrids, all-electric ships are mobile transportation vehicles, complying with the regulation of safe return to port. In order to enhance the resilience and improve energy efficiency of mobile microgrid, this study proposes a two-stage economic and resilient optimization framework for an all-electric ship (AES), taking into account the impact of navigation. In the first stage, a joint voyage and power scheduling of the AES is developed to reduce the operation costs and greenhouse gas emissions for normal operation mode. In the second stage, resilience-oriented optimization is proposed to defend the extreme contingency by optimizing the navigation speed and load shedding. Furthermore, resistance during the whole AES navigation is also considered. To verify the proposed algorithm, several cases are compared to demonstrate the resilience and economy of the shipboard power system and the necessity of addressing the effect of sailing resistance on the AES voyage.

考虑安全返回的全电动船舶弹性能源管理

船舶电力系统与外部电网隔离，使其比陆基电力系统更脆弱。此外，与陆地固定微电网不同，全电动船舶是移动运输工具，符合安全返港规定。为了增强移动微电网的弹性和提高能源效率，本研究提出了考虑航行影响的全电动船舶(AES)两阶段经济和弹性优化框架。第一阶段，为降低AES正常运行模式下的运行成本和温室气体排放，提出AES航次与功率联合调度方案。在第二阶段，提出了面向弹性的优化，通过优化导航速度和减载来防御极端偶然性。此外，还考虑了整个AES导航过程中的电阻。为了验证所提出的算法，比较了几个实例，证明了船载电力系统的弹性和经济性，以及解决航行阻力对AES航行影响的必要性。
