Why This Topic Matters
A fuel-cell electric-vehicle and vehicle-to-grid model that coordinates fuel-cell power, the vehicle DC link and a grid-connected inverter during mobility, charging and grid-support operation.
For academic work, the model should connect every claimed improvement to a measurable output. A reliable workflow begins with a validated baseline, introduces one controlled modification at a time and uses repeatable scenarios for comparison.
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.
Recommended MATLAB Simulink 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
Step-by-Step Modelling Workflow
- 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.
Simulation Cases to Include
- 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
Graphs and Results to Discuss
- 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
Do not report a curve only as “improved.” State the event time, compare the reference and measured signals, calculate relevant indices and explain the physical reason for the change.

Common Modelling Mistakes
- Using inconsistent base values, units or sign conventions across subsystems.
- Tuning all control loops simultaneously instead of validating the inner loops first.
- Comparing controllers under different initial conditions or disturbances.
- Ignoring actuator, converter, current, SOC, temperature or power limits.
- Presenting scope screenshots without quantitative result interpretation.
