Optimal economic and pollution-constrained management of a hybrid DC shipboard power system

Abstract

The integrated topology of shipboard power system has been more and more adopted in All Electric Ship design to benefit from the economic, technical and environmental advantages that it offers. Though, the resulting integrated shipboard power system becomes more heterogeneous and complex; making power system management a challenging task. This study presents an innovative approach for shipboard power system management of a cruiseferry. The power management combines both power production minimization and air-pollution limitation. The study focuses on the determination of the optimal operating plan of controllable power sources in addition to an adaptive ship speed control to adjust total power load. The optimization problem was formulated and implemented in the General Algebraic Modeling System and it was solved using the Mixed Integer Non Linear Programming Solver.
