Welcome

Welcome to the Power System Control and REnewable IntEgratioN (PSCREEN) lab. The PSCREEN lab is directed by Dr. Yichen Zhang, Assistant Professor of the Department of Electrical Engineering, College of Engineering, The University of Texas at Arlington, and empowered by our students, postdocs, and all our lab supporters.

At the PSCREEN, we draw on the diverse methods from optimal control, machine learning, formal methods, control and system theories to aid in the decision making of cyber-physical power systems, with particular interest on power systems with large-scale inverter-based resources. Particularly, we are interested in:

  • Power system dynamics and control, renewable integration, wind turbines, frequency regulation of low-inertia grid
  • Microgrid control, voltage-source converter, grid-interactive and grid-forming converters
  • Formal verification, reachability analysis, hybrid systems, and their application in power systems
  • Optimal control, robust control, numerical optimal control, reinforcement learning, and their application in power systems
  • Surrogate optimization, machine learning for combinatorics, and their application in power systems
  • Embeddable and distributed decision-making algorithms, control-in-the-loop real-time simulation for power systems

Here are some digital media about our research:
