When generated by water or wind sources, electricity is one of the cleanest and most sustainable forms of energy. All the same, extracting power from such sources calls for careful planning and management, since it hinges largely on random (stochastic) phenomena: the water used to generate electricity comes from snowmelt and rain runoff, while wind energy is highly variable, uncontrollable and only partially predictable in the short term.

Held by Michel Gendreau, Full Professor with Polytechnique's Department of Mathematics and Industrial Engineering, the NSERC/Hydro-Québec Industrial Research Chair on the Stochastic Optimization of Electricity Generation will focus on developing effective, efficient approaches to dealing with the challenges of stochastic optimization encountered in managing electric power systems driven by wind or water sources.

"One of the biggest issues facing Hydro-Québec is the need to maximize energy production in a timely manner, using the available resources," says Christophe Guy, Chief Executive Officer of Polytechnique. "The Chair seeks to facilitate this task by developing mathematical models for optimizing the management of electricity-generation operations. We are proud to count Hydro-Québec among our partners, thus confirming our position as a Canadian leader in engineering research."

Pushing the limits of existing optimization models
Certain stochastic optimization models have been explicitly designed to take randomness into account. However, while researchers are able to write equations for these models, no computer has the capacity to integrate quite so many variables. "Modelling water supply is already a problem in itself. But when combined with the state of the network, historical patterns in time and space, and data from the many reservoirs, the calculations explode," notes Professor Gendreau.

As part of its research, the Chair will require concrete data to verify the models. Historical data from Hydro-Québec, combined with synthetic data to generate comparisons with reality, will play a key role in the Chair's work. Hydro-Québec, in turn, is pleased to support the development of knowledge in the field. Gaétan Lantagne, Scientific Director of the Institut de recherche d'Hydro-Québec (IREQ), said: "The Chair's work will help us train new resources who can work in tandem with IREQ experts. Together, they'll develop innovative management tools that can help us better plan for hydroelectricity generation and the integration of wind power."

The Chair's research will entail a two-pronged approach involving both methodological considerations and specific applications. The methodological aspect will focus on developing and assessing new computational methods for solving problems of optimization in the presence of uncertainty. As for applied projects, the Chair will develop models and methods for use in the co-ordinated management of the bulk power system or in hydrological systems with multiple large reservoirs.

"An international leader in the area of optimization, Professor Gendreau possesses the expertise and experience required to make important contributions to the management of electricity generation systems," said Dr. Fortier, president of NSERC. "In addition to allowing Hydro-Québec and other power authorities to use their water resources more efficiently, this Chair will offer particularly strong training opportunities for the students and personnel involved." 

About NSERC
NSERC is a federal agency that helps make Canada a country of discoverers and innovators for all Canadians. The agency supports some 30,000 postsecondary students and postdoctoral fellows in their advanced studies. NSERC promotes discovery by funding more than 12,000 professors every year and fosters innovation by encouraging more than 1,500 Canadian companies to participate and invest in postsecondary research projects.

About Hydro-Québec
Hydro-Québec generates, transmits and distributes electricity. Its sole shareholder is the Québec government. It uses mainly renewable generating options, in particular hydropower, and supports the development of wind energy through purchases from independent power producers. It also conducts R&D in energy-related fields, including energy efficiency. For more information on Hydro-Québec, please visit www.hydroquebec.com.
