Introduction
High power transportations account for a great amount of greenhouse gas. For example, maritime transport is responsible for 3% global greenhouse gas emission; rail transport is responsible for 4%. To reduce the emission, high power transportation sectors are going through the electrification with the utilization of clean energy sources. Fuel cell based high power transportations are key enablers for the reduction of emission. For the power systems of fuel cell based transports, there are sources (e.g., fuel cells) and loads (e.g., motors), as well as various power electronic converters, which are integrated to provide power conversion or propulsion as well as the controllability of the whole power system. To enable a full realization of fuel cell based high power transportation for efficient energy use, emission reduction and cost saving, it is important to perform system level design, analysis and control. Modeling and simulation of such system are the essential tools to facilitate the system level studies.
Objectives:
This project is conducted with ABB. The overall objective is to develop a comprehensive system modeling and simulation of fuel cell based high power transportations to provide accurate and effective simulation for system level studies. Tasks include:
- Study the configurations of fuel cell based high power transportations (all electric ships or electric trains)
- Development of model library of subsystems, and then conduct model validation regarding specifications
- Model integration at system level, and perform simulation validation according to data or standards
- Simulation study of system performance under various loading profiles to investigate the varying load impacts on the system performance and assess the standard compliance
- Write the master thesis
Requirements on students:
We are looking for one master thesis student (30 hp) in the field of electric power systems with:
• Good knowledge of power electronics, especially in modeling and control of power converters
• Good knowledge of fuel cell and energy storage systems
• Strong MATLAB/Simulink skill
