Based on various combinations of combustion turbines (CTs) and steam turbines (STs), a combined-cycle unit could work at different configurations (modes) with different efficiency levels. In this work, we propose an edge-based formulation for the combined-cycle units in the unit commitment problem to improve the accuracy and effectiveness of state-of-the-art modeling approaches. Our formulation can (1) clearly describe the transition processes among different configurations so as to satisfy the ISO financial offer submission requirements and (2) capture physical constraints of each turbine, including the exact min-up/down time and time dependent startup cost, in the combined-cycle units in order to increase the operational flexibility while ensuring system operation feasibility. The proposed model fits well with the current U.S. deregulated electricity market. The final numerical studies show that our approaches perform better than the current configuration-based modeling approach used in ISO practice.报告人简介：Dr. Lei Fan received his B.S. degree in Electrical Engineering from the Hefei University of Technology, Hefei, China, in 2009 and Ph.D. degree from the Department of Industrial and Systems Engineering at the University of Florida, Gainesville, FL, United States, in 2015. During 2009-2012, he studied at the College of Electrical Engineering, Zhejiang University. His research interests include large-scale mixed-integer linear programming, data-driven stochastic programming, power system operation and planning, and electricity market analysis. He worked at several energy companies including Alstom Grid, Midcontinent Independent System Operator (MISO), and General Electric (GE). Now he works as an electricity market software developer at SIEMENS Industry, Inc in Minnetonka, MN, United States.
