Project Objective
Study how a fuel-cell vehicle can exchange controlled active and reactive power with the grid while respecting stack dynamics, DC-link regulation, auxiliary storage limits and hydrogen-consumption constraints.
The page is written to help researchers move from a project title to a structured model, a defendable simulation methodology and a clear set of result graphs without claiming fixed performance before the final parameters are selected.
System Architecture and Main Blocks
- Fuel-cell stack with polarization and dynamic response
- Hydrogen supply and consumption calculation
- Unidirectional or bidirectional DC–DC converter
- Vehicle DC link and optional battery/supercapacitor buffer
- Grid-connected voltage-source inverter and filter
- PLL, current controller, active/reactive power controller and V2G supervisor
MATLAB Simulink Methodology
- Parameterize the fuel-cell stack, converter, DC link, grid and vehicle power demand.
- Validate fuel-cell voltage/current response before enabling V2G exchange.
- Tune DC-link and grid-current loops with appropriate bandwidth separation.
- Define mobility, parked, charging and V2G-support operating modes.
- Evaluate power quality, stack loading, DC-link stability and hydrogen use during command changes.
Recommended Simulation Scenarios
- Vehicle propulsion followed by parked V2G mode
- Grid active-power export step
- Reactive-power or voltage-support command
- Grid-voltage disturbance
- Fuel-cell power-rate and hydrogen-use constraint comparison
Expected Outputs and Performance Metrics
- Fuel-cell stack voltage, current and power
- Hydrogen consumption or utilization rate
- DC-link voltage and converter duty ratio
- Grid current, active power, reactive power and power factor
- Vehicle/auxiliary-storage energy state and operating-mode timeline
Results should be plotted with labelled axes, units, reference signals and event times. Baseline and proposed-control cases should use the same operating conditions for a fair comparison.

Suggested Report Structure
A strong report can include problem definition, literature review, governing equations, system block diagram, parameter table, controller design, simulation cases, result discussion, limitations, proposed novelty and future scope. Screenshots should be accompanied by technical interpretation rather than presented without explanation.
