Title: Reliability-constrained hydropower valuation

Abstract: Maximizing the long-term value of hydropower generation requires management of uncertain reservoir inflows, potentially variable constraints on outflows, and exposure to possibly wildly varying power prices. In this talk we present a stochastic dynamic programming approach to the quantification of reservoir reliability (for example, measures of the risk of over-topping the reservoir or failing to satisfy downstream flow requirements) and a related approach to determining the reservoir flow strategy that maximizes expected revenue, subject to defined target reliability levels.

Last Thursday, February 16, 2017, Dr. Michael P. Lamoureux who is a faculty member at the Department of Mathematics and Statistics of the University of Calgary gave a presentation entitled Grid Algebra and Finite Difference Methods.
Dr. Lameroux talked about two-dimensional and three-dimensional finite difference method for the wave equation with constant velocity. In particular, how to develop a numerical algorithm for the wave equation. Some numerical simulations were also presented.

The audiences were from different backgrounds including undergraduates, graduates and postdocs and faculty members. Here are some pictures of this event.

Title: Grid algebra and finite difference methods

Abstract: We are all familiar with linear algebra and methods for representing linear operators as an n by n matrix. Today, we will discuss representing operators on a 2D or 3D grid, or more generally on a directed graph. We develop linear algebraic methods to simplify or factor the operator into a form that is easy to solve using back-substitution. Such techniques are useful in numerical solutions of partial differential equations. We apply the technique to implement an implicit solver for a finite difference algorithm applied to the wave equation in two dimensions.
