Tim Magee presented “Production Cost Model Evaluation with a Hydropower Operations Model” on November 9, 2020, at the annual meeting of INFORMS, the leading international association for operations research and analytics professionals. Co-authors were Mitch Clement and Edith Zagona of CADSWES and Nathalie Voisin of Pacific Northwest National Labs.

Abstract: Grid-scale production cost models (PCMs) optimize generation and transmission of electricity to meet load. Hydropower is an important component of these models because its flexibility aids the addition of intermittent renewable generation, such as wind and solar power, to the grid. Grid-scale PCM models do not include many of the factors that limit hydropower flexibility. We reuse a detailed RiverWare model of the Columbia River used in daily operations both to evaluate existing PCM simulations over the North American Western Interconnect and to improve the representation of hydropower in PCMs. The RiverWare model uses a combination of goal programming methods that reflect policy priorities for power and nonpower purposes. The model can precisely evaluate the flexibility effects of factors such as reservoir storage state, forecasted inflows and seasonal constraints.

At the Institute for Operations Research and the Management Sciences (INFORMS) 2020 virtual annual meeting, held Nov. 7–13, 2020, Tim Magee of CADSWES presented “Production Cost Model Evaluation with a Hydropower Operations Model.” INFORMS is the leading international association for operations research, management science and analytics.

CADSWES and CEAE collaborators contributed several presentations to the 10th iEMSs Conference, September 14–18, 2020, in Brussels, Belgium. The conference is sponsored by the International Environmental Modelling and Software Society. Following are the presenters and their presentations (and authors).

Mitch Clement: “Complex Hydro-policy Modeling with RiverWare for Collaborative Multi-objective River System and Hydropower Planning and Operations” (Clement, Zagona)
Nathan Bonham: “Evaluation of Scenario Discovery Methods for Multi-Reservoir System Planning” (Bonham, Kasprzyk, Zagona)
Joe Kasprzyk:
- “Improving Interpretability of Multi-Objective Tradeoff Sets for Environmental Systems” (Kasprzyk, Smith, Raseman, Jacobson, Balaji)
- “Multiobjective Optimization to Support Long-term Water Treatment Planning” (Kasprzyk, Raseman)
- “Using Multiobjective Evolutionary Algorithms and RiverWare for Generating Robust Lake Mead Operating Policies” (Kasprzyk, Elliot, Zagona, Smith, Prairie, Jerla, Butler)

Collaborators from CADSWES and CU Boulder Civil, Environmental and Architectural Engineering (CEAE) delivered multiple presentations at the 10th annual International Environmental Modelling and Software Society (iEMSs) event, hosted virtually via Zoom from Brussels, Belgium.
