The Research of Power Allocation in Diesel-electric Hybrid Propulsion System

In the traditional diesel engine propulsion mode, the ships face up to a serial of issues, such as the inefficient performance of marine main engine under low load, the high fuel consumption rate and inferior combustion quality, which hinder the income increase and the pollution decrease. Dieselelectric hybrid propulsion ships can effectively reduce fuel consumption and emissions through reasonable power distribution. Moreover, it also has excellent handling performance and low noise. Taking a certain Deep Water Anchor Handling Tug Supply Vessel as the object, the multiobjective genetic algorithm (NSGA-II) was used to optimize the allocation problem of the power system. The optimization calculation and simulation verification were carried out by using MATLAB.
