The Sustainable Power Systems Laboratory (SPS-Lab) is led by Dr. Petros Aristidou and is part of the Department of Electrical Engineering and Computer Science and Engineering at the Cyprus University of Technology (CUT), Limassol, Cyprus.
We work on making future electric power systems sustainable, secure, and resilient. Our research bridges mathematical tools from numerical analysis and optimization with high-performance computing and machine learning to tackle modern power system challenges.
- Power System Dynamics & Stability — Transient stability, small-signal analysis, low-inertia grids
- Real-Time & Time-Domain Simulation — Advanced simulation tools for large-scale power systems
- Renewable Energy Integration — RES hosting capacity, curtailment strategies, frequency security
- Smart Grids & Active Distribution Networks — Volt-Var optimization, EV flexibility, demand response
- Machine Learning for Power Systems — Data-driven control, safe multi-agent reinforcement learning
- Energy Planning & Optimization — District heating/cooling, virtual power plants, EMS
