Transient Stability Analysis Of Battery With Fuel Cell Driven To Electric Powertrain

In marine industry, fuel cell (FC) is being exploited as the primary power source with battery energy storage system (BESS) as complementary resource to be introduced for peak shaving and smoothing control in load fluctuation. As such, an integrated system of Proton Exchange Membrane Fuel Cells (PEMFC) with BESS is being developed to propose to meet the dynamic three-phase load demand onto micro-grid configuration. In this paper, transient stability is verified by MATLAB/Simulink has shown BESS is more adaptable than FC to meet constant and dynamic load demand. Moreover, there is an unstable power generation from PEMFC when non-linear load is introduced. As such, in micro-grid's paradigm that consists of BESS that has same energy capacity as FC, can significantly enhance output power quality during transient period to electrified dynamic load. In addition, a proposed control algorithm is designed in this paper.
