ABSTRACT
This study proposes a consecutive market and network simulation approach to investigate grid investment, redispatch and renewable energy source (RES) curtailment requirements under various RES penetration scenarios. Market simulation represents market clearing process in power-exchange day-ahead markets hourly for the entire target year. Network simulation represents the role of transmission system operators in determining optimum re-dispatch orders to conventional power plants and curtailment orders to RES, in order to ensure security and reliability of the power system. Cost-benefit and reliability driven transmission grid investment requirements are calculated iteratively by market and network simulations, respectively. The proposed approach enables investigation of not only network constraints introduced by the intermittent characteristics of RES power plants but also proper planning and operational solutions. Both market and network simulations are formulated as mixed integer programming problems. Benders decomposition technique along with augmented Lagrangian relaxation is utilized to solve the problems along the target year while satisfying constraints connected with the simulations. Numerical case studies are performed for low, moderate, and high RES scenarios for the Romanian power system in 2030.
BIOGRAPHY
Assoc. Prof. Dr. Osman Bülent Tör received his B.S., M.S., and Ph.D. degrees in Electrical and Electronics Engineering from Middle East Technical University (METU), Ankara, Türkiye, in 1998, 2001, and 2008, respectively. He was a visiting scholar in Electrical and Computer Engineering of Illinois Institute of Technology (IIT), Chicago, IL, USA between Sep. 2004 - Aug. 2005. He received his Assoc. Prof. (Doç.) degree in Electrical and Electronics Engineering from Inter-University Council of Türkiye in 2020. He was part-time lecturer at METU, Ankara, Türkiye between 2011-2014 and opened Power System Planning and Stability and Dynamics of Power Systems courses (graduate) at that period. He also opened Power System Distribution-I&II courses (under-grad) as part-time lecturer at TOBB Economy and Technology University, Ankara, Türkiye between 2011-2013. He is the author of several journal and conference papers in the power system area and served as the editor of the IEEE Transactions on Power Systems Journal during 2011-2013, specializing in power system planning area. With 25+ years of experience in the electrical power sector, he has managed several national and international projects in the power systems area for public and private clients in the following area; electric market modeling, power grid modeling and analysis (static & dynamic), SCUC analysis, ancillary services in power markets, integrating renewable energy sources into grids, flexibility of power systems, stability and dynamics of power systems, and optimization techniques in power systems. He currently serves as the CEO and partner of EPRA Energy since 2012. Before this position, he led the Power Systems Analysis and Planning Department of TÜBİTAK-MAM-Energy Institute Ankara, serving as a chief R&D engineer (power systems) for 12 years.
