Title: Nonlinear Stochastic Dynamics of Pressure in Natural Gas Networks. Abstract: A dominant new load on the gas pipelines is natural gas-fired generators. Previously, the marginal cost of electricity from these generators was higher than from coal-fired generators. However, the rapid drop in gas prices has made gas generation competitive with coal and spurred its construction. An example of this dramatic expansion is in the electrical grid controlled by the Independent System Operator of New England (ISO-NE) where natural gas-fired electrical generation increased from 5% of total capacity to 51% in a span of 20 years. A parallel development in many U.S. electrical grids is the expansion of intermittent renewable generation such as wind and Photo Voltaic generation -- a trend that is expected to continue as utilities work to meet state-imposed renewable portfolio standards that mandate a certain fraction of electrical generation be derived from renewable sources. During a talk we shall give introduction to the theoretical model and discuss different simulation techniques.
