Pressure Transients and Fluctuations in Natural Gas Networks caused by Gas-Electric Coupling Natural gas-fired generators are often used to balance the fluctuating output of wind generation within electric power transmission systems. However, the time-varying output of these generators results in time-varying natural gas burn rates that impact the pressure in interstate transmission pipelines. Fluctuating pressure impacts the reliability of natural gas deliveries to those same generators and the safety of pipeline operations. Motivated by this new emerging significance of the gas-grid coupling I start the talk reviewing gas-dynamic models of natural gas pipelines and describe how to utilize this modeling to explore the effects of intermittent wind generation on the fluctuations of pressure and transients in natural gas pipelines. I will also discuss significance, use and peculiarities of the gas-dynamics modelings and simulations in gas-grid stochastic optimization and control problems. Bio:
Dr. Chertkov's areas of interest include statistical and mathematical physics applied to energy and communication networks, machine learning, control theory, information theory, computer science, fluid mechanics and optics. Dr. Chertkov received his Ph.D. in physics from the Weizmann Institute of Science in 1996, and his M.Sc. in physics from Novosibirsk State University in 1990. After his Ph.D., Dr. Chertkov spent three years at Princeton University as a R.H. Dicke Fellow in the Department of Physics. He joined Los Alamos National Lab in 1999, initially as a J.R. Oppenheimer Fellow in the Theoretical Division. He is now a technical staff member in the same division. Dr. Chertkov has published more than 150 papers in these research areas. He is an editor of the Journal of Statistical Mechanics (JSTAT), associate editor of IEEE Transactions on Control of Network Systems, member of the Editorial Board of Scientific Reports (Nature Group), a fellow of the American Physical Society (APS) and a senior member of IEEE. |
