  This paper presents an original energy management methodology to enhance the
resilience of ship power systems. The integration of various energy storage
systems (ESS), including battery energy storage systems (BESS) and
super-capacitor energy storage systems (SCESS), in modern ship power systems
poses challenges in designing an efficient energy management system (EMS). The
EMS proposed in this paper aims to achieve multiple objectives. The primary
objective is to minimize shed loads, while the secondary objective is to
effectively manage different types of ESS. Considering the diverse ramp-rate
characteristics of generators, SCESS, and BESS, the proposed EMS exploits these
differences to determine an optimal long-term schedule for minimizing shed
loads. Furthermore, the proposed EMS balances the state-of-charge (SoC) of ESS
and prioritizes the SCESS's SoC levels to ensure the efficient operation of
BESS and SCESS. For better computational efficiency, we introduce the receding
horizon optimization method, enabling real-time EMS implementation. A
comparison with the fixed horizon optimization (FHO) validates its
effectiveness. Simulation studies and results demonstrate that the proposed EMS
efficiently manages generators, BESS, and SCESS, ensuring system resilience
under generation shortages. Additionally, the proposed methodology
significantly reduces the computational burden compared to the FHO technique
while maintaining acceptable resilience performance.
