IDEAL Lab
Intelligent Decarbonization for Energy Access and Reliability
Grid intelligence for reliable, affordable clean electricity.
The IDEAL Lab develops optimization, dynamics, and cyber-physical modeling methods for renewable-rich power systems. Led by Dr. Xin Fang at the University of South Carolina, the lab connects rigorous power-system theory with practical tools for planning, operating, and securing the future electric grid.
Research Focus
Optimization and Markets
Planning and dispatch methods for high-renewable systems, electricity market design, capacity expansion, and stability-aware economic operation.
Dynamics and Stability
Frequency response, small-signal stability, virtual inertia, inverter-based resources, and analytical constraints that bridge dynamics with operations.
Grid Planning with Renewables
Capacity expansion, transmission planning, and resource adequacy methods that help renewable-rich grids meet reliability, resilience, and decarbonization goals.
Cyber-Physical Co-Simulation
Transmission-and-distribution co-simulation, distributed energy resource integration, electric transportation, and scalable grid digital twins.
Recent Highlights
