Decentralized Generation Scheduling in Energy Networks


Day-ahead scheduling of electricity generation or unit commitment is an important and challenging operational activity of power system operators. Mixed integer programming (MIP) has been firmly established

as an effective technology for this problem for moderate scale integrated systems. In this work, we consider decentralized unit commitment in a large-scale network of generation systems. We develop a

decomposition-coordination approach by which independent unit commitment MIP models can be integrated to achieve high quality solutions to the network-wide problem. The approach is based on the alternating direction

method of multipliers (ADMM) developed for decentralized convex optimization. We adapt ADMM to the highly nonconvex unit commitment problem and demonstrate its computational effectiveness.


Shabbir Ahmed is a Professor in the H. Milton Stewart School of Industrial & Systems Engineering at the Georgia Institute of Technology. His research interests are theoretical and algorithmic aspects of

large-scale optimization, specifically stochastic and integer programming. Dr. Ahmed serves or has served on various leadership positions in professional societies and on editorial boards of leading

journals in optimization. Dr. Ahmed's honors include the National Science Foundation CAREER award, two IBM Faculty Awards, the Coca-Cola Junior Professorship from ISyE, and the INFORMS Dantzig Dissertation award.

***This is joint work with PhD students Javad Feyzollahi (ISyE) and Mitch Costley (ECE); and Professor Santiago Grijalva (ECE)***
