Power Management Method for Clean Energy Ships Based on Supply Capacity Constraints

Ships that use clean energy as power can effectively reduce environmental pollution. The power management of clean energy ships has attracted widespread attention from the industry in recent years. However, the existing research on power management issues don't comprehensively consider the security of ship navigation. If the supply capacity constraints are considered in the ship's power system to make the system operate within a safe boundary, the security of the ship will be greatly improved. This paper constructs the power system based on a chopper and proposes a multi-constrained optimization management system for new energy ships, aiming at minimizing the operation cost. The supply capacity constraints are considered in this paper so that the power system can meet the N-1 power security guidelines. After considering the N -1 power security guidelines, even if the ship's power supply equipment is damaged, the ship's safe and stable operation can still be guaranteed. Finally, the simulation results of the paper prove the effectiveness of the algorithm.
