Seminar Title: Stochastic Optimal Control Framework for Natural Gas Network Operations
Speaker: Victor Zavala, Assistant Computational Mathematician

Date/Time: 2013-11-20 15:00
Location: Building 240, Room 1404-1405


Description:
We present a stochastic optimal control framework to optimize gas network inventories in the face of system uncertainties. The model captures detailed network dynamics and operational constraints and uses aweighted risk-mean objective. We perform a degrees-of-freedom analysis to assess operational flexibilityand to determine conditions for model consistency. We compare the control policies obtained with thestochastic model against those of deterministic and robust counterparts. In addition, we demonstratethat the use of risk metrics can help operators to systematically mitigate system volatility. Moreover,we discuss computational scalability issues and effects of discretization resolution on economic performance.
