MPC-informed ECMS based real-time power management strategy for hybrid electric ship

Shipboard power systems (SPS) are complex connecting multiple sources, energy storage (ESSs) and various types of loads. However, the fluctuated propulsion loads may lead to a low quality system. In this paper, management system (PMS) is designed for SPS in framework an optimization-based method. With equivalent consumption minimization strategy (ECMS), proposed method able provide optimal power-split between hybrid sources real time, while minimizing fuel Furthermore, equivalence factor adjusted by model predictive control (MPC) PMS. The performances approach evaluated simulations.
