Electrical Power & Energy Systems

The Electrical Power and Energy Systems (EPES) Lab enables the analysis, design and implementation of complex energy and power networks from device to circuitry and system levels.


  • Power hardware-in-the-loop (PHIL) system
    • Test off-grid, grid-connected and microgrid technologies (OPAL-RT) to measure energy efficiency, power quality and stability. Implement control and protection schemes when exposed to real-world grid operating conditions.
  • 2D/3D magnetic property testers
    • Measure and collect raw data of advanced electromagnetic materials for in-depth mechanism understanding and proper mathematic models, which are crucial for developing high-performance electromagnetic devices like electrical machines and transformers.
  • Electrical machines test benches
    • Measure major parameters and characteristics of electrical generators and motors, e.g. motor torque-speed curves for EV drives.
  • Conducted Electromagnetic Interference/Electromagnetic Compatibility (EMI/EMC) testing facility
    • Test both ac/dc electrical and electronic equipment to reach pre-compliance with national and international safety standards.
  • 30kVA 4-quadrant AC power supply
    • Interface with PHIL for power inverter design, testing and analysis of energy flow, power quality, stability, etc.
