Decision Support for Integrated Electricity and Natural Gas System Planning under Uncertainties: A Real Options Approach
Zhuoyi Zhao, Dr. Cameron MacKenzie and Dr. K Jo Min, Iowa State University
Moderator: Jeff Gorrie
Wednesday, 9:30-10:20 in Salon 2&3
The Solar and Wind Energy using Engineering Economics Theory (SWEEET) project is studying the economic viability of incorporating more solar and wind energy into Iowa’s electrical grid. The project focuses on how these renewable energy sources can better serve rural and underserved areas. This project is funded by the Iowa Energy Center. You can find preliminary results and some technical notes from the project as well as other relevant publications, more technical documents, and links to information on Iowa’s electric power network.
Download the Excel tool for optimal power flow (downloads as zip file). See teaching modules on DC optimal power flow and locational marginal price. Make sure to enable content for macros when Excel sheet opens. You will also need Solver loaded in Excel (for free).
Download the Excel tool for option valuation for 5 periods. See teaching modules on demand lattice (a model to consider uncertainty over time) and valuing an option (for new sources of electricity generation)
SWEEET 2022 Public Workshop was held on August 8, 2022. This public workshop is aimed at helping utilities and independent power producers plan strategically for the future and apply engineering economic principles when making decisions about new sources of renewable power and new transmission lines.
Distributed solar and wind power generation planning in rural and underserved areas
- Many such generators are located in rural areas
- When new solar and wind power is added, the grid will be impacted. A lack of transmission capacity may increase electricity prices (e.g., locational marginal price)
- President Biden announced goal of making U.S. carbon neutral by 2050
Benefits of Our Approach
- Provide ratepayers with lower electricity bills
- Enable state of Iowa to be more responsive to carbon neutral targets
- Provide cleaner energy to Iowa residents
Goals of the Project
- Locate renewable generation units of right sizes at right places at right times
- Understand the ramifications and economic consequences of new generation sources on the existing grid
- Guidance to risk averse decision makers
- Produce a set of guidelines and recommendations for practitioners, academics, and decision and policy makers
- SWEEET was represented at the Institute for Industrial and Systems Engineers Annual Conference in Seattle, Washington in May 2022. Cameron MacKenzie presented the research on valuing options in electricity generation and planning. Xue Lei presented on designing a flexible energy portfolio for Iowa. Her conference paper can be found here.
- Public mini-workshop will be held in Ames in August 2022 to review the progress and disseminate results! To be updated soon.
- Nazia Nur won the “Graduate best poster: Third Prize” in the 10th Annual Student Research Symposium arranged by the Department of Industrial and Manufacturing Systems Engineering for her poster on “How to value an option to add a generator under uncertainties”. In this poster, she discussed the decision-making process for adding a generator considering electricity demand uncertainty.
Jo Min, associate professor in industrial and manufacturing systems engineering (IMSE), is the principal investigator, and Cameron MacKenzie, assistant professor in IMSE, is the co-principal investigator.
