Master Thesis: Grid Code Compliance of Large Data Centers

About the role

Hitachi Energy is offering a full-time master thesis in Gothenburg, Sweden, investigating European and Nordic grid code requirements for large-scale data center connections. The project focuses on compliance risks related to voltage and frequency stability, voltage ride-through (VRT), power quality, load ramping and control interactions, and evaluates mitigation solutions such as BESS, STATCOMs and synchronous condensers.

Key responsibilities

• Review European and Nordic grid codes relevant to large data center interconnections.
• Identify technical risks of non-compliance, including voltage ride-through, voltage and frequency stability, interaction phenomena, power quality and load ramping.
• Develop data center and power system models in PSCAD and PowerFactory/PSS®E.
• Run dynamic simulation studies to assess performance during grid disturbances and faults.
• Evaluate mitigation measures such as grid-forming BESS, STATCOMs, MV UPS systems and harmonic filters.
• Compare the effectiveness, advantages and limitations of different mitigation options.
• Develop recommendations and best practices for integrating AI and hyperscale data centers into power systems.

Required profile

• Master's student in electrical engineering, electrical power systems or a similar field.
• Knowledge of power system analysis, power electronics or control systems.
• Strong analytical and problem-solving skills.
• Understanding of working in a multicultural environment.
• Proficiency in written and spoken English; Swedish is an advantage.

Required skills

• Experience with Python, PSS®E, PowerFactory, PSCAD, MATLAB/Simulink or similar simulation tools.
