Welcome! to the ACES Laboratory in the School of Electrical and Computer Engineering at Georgia Tech. The ACES Laboratory is an advanced environment for the development of transformational research to address challenging problems in electricity grids by the use of sophisticated software, algorithms, machine learning, and computation methods. We focus on the “systems” aspects of the electricity grid at all scales, from bulk power systems to home appliances.
ACES Research Areas
- Real-Time Power System Control, Operation and Computation
- Renewable Energy Integration into the Grid
- Machine Learning and AI Applications to Power Systems
- Cyber-Physical Security of Energy Systems
- Electricity Economics, Markets and Planning
- Distributed Energy Prosumers and Energy Internet
Director: Prof. Santiago Grijalva
Dr. Santiago Grijalva is the Southern Company Distinguished Professor of Electrical and Computer Engineering. He is a leading researcher on power system operation, electricity markets, and smart grids. He is a pioneer in the areas of decentralized power system control, DER integration into the grid, and Internet of Energy. Prior to joining Georgia Tech in 2009, he spent 10 years in the power industry, developing of commercial grade algorithms for real-time power system control, optimization, and visualization. He graduated with his M.Sc. and PhD degrees from the University of Illinois at Urbana-Champaign in 1999 and 2002, respectively. |
