Adaptive Voyage-Generation Scheduling in Shipboard Microgrid under Time-varied Weather Conditions

Fully electrification of ships brings great operating flexibility, which makes the shipboard microgrid can quickly respond to various navigation disturbances. In this paper, an adaptive voyage-generation scheduling in shipboard microgrid is proposed for addressing the time-varied weather conditions along the navigation route. The first stage is a pre-voyage planning and determines a tentative navigation route and cruising speed scheme with minimal fuel cost under pre-voyage forecasting weather conditions. The second stage is an on-line recourse based on intra-voyage forecasting weather conditions, which modifies the navigation route and cruising speed to keep away from the routes with adverse weather conditions and determines the onboard generation schemes. A 4-DG AES in a real-world weather routing scenario is set as the test case. Simulation results demonstrate the proposed method can well adapt to the time-varied weather conditions when navigation, and provide a safe and economic voyage-generation scheme.
