Integrated Resource Plan For Portland General Electric (Pge), Mary Biswal, Alejandro Castelan
Integrated Resource Plan For Portland General Electric (Pge), Mary Biswal, Alejandro Castelan
Master's Projects and Capstones
An integrated resource plan (IRP) for Portland General Electric (PGE) is developed in this master’s project. The IRP is based on capacity expansion modeling for zero-carbon emission scenarios. PGE is a public electric utility based in Oregon and serves around 887,000 customers across a territory of 4,000 sq. miles. The utility’s resource mix is currently heavily dependent on natural gas making up almost 50% of its capacity. While the state renewable portfolio standards (RPS) require Oregon power utilities to derive 50% of their generation from renewable sources by 2040, PGE plans to move rapidly into a clean energy mix by …
An Integrated Resource Plan For Arizona Public Service Electric (Aps), Irene Boghdadi, Randy Chiu
An Integrated Resource Plan For Arizona Public Service Electric (Aps), Irene Boghdadi, Randy Chiu
Master's Projects and Capstones
Our Masters Capstone Project is an Integrated Resource Plan (IRP) for Arizona’s largest electric utility, Arizona Public Service Electric (APS).
An IRP is developed by utilities to identify the optimal combination of demand- and supply-side resources needed to reliably meet forecasted demand for energy and capacity, including a planning reserve margin, over a future period.
In addition to APS’s obligation to serve the growing load in Arizona while minimizing costs, it is required by the state to adhere to the Renewable Energy Standard (RES) policy of 15 percent retail sales from renewable energy resources by 2025.
The analysis described in …
How Can Occupancy Modeling And Occupancy Sensors Reduce Energy Usage In Academic Buildings: An Application Approach To University Of San Francisco, Paloma R. Duong
How Can Occupancy Modeling And Occupancy Sensors Reduce Energy Usage In Academic Buildings: An Application Approach To University Of San Francisco, Paloma R. Duong
Master's Projects and Capstones
Buildings are amongst the highest energy consumers relative to industry and transportation. They account for 40% of the world’s energy consumption, due to the need for lighting, equipment, heating, cooling and ventilation. Academic buildings are multi-purpose buildings that create a challenge on energy reduction. Most are old and have fixed occupancy schedules, resulting in high energy consumption because these buildings experience significant occupancy variation throughout the day. Five academic buildings were analyzed; their building information, energy consumption data and methods to project energy savings have been analyzed. The case studies presented different strategies on predicting energy savings, but these have …

Vorticity Dynamics And Sound Generation In Two-Dimensional Fluid Flow, Raymond J. Nagem, Guido Sandri, David Uminsky
Mathematics
An approximate solution to the two-dimensional incompressible fluid equations is constructed by expanding the vorticity field in a series of derivatives of a Gaussian vortex. The expansion is used to analyze the motion of a corotating Gaussian vortex pair, and the spatial rotation frequency of the vortex pair is derived directly from the fluid vorticity equation. The resulting rotation frequency includes the effects of finite vortex core size and viscosity and reduces, in the appropriate limit, to the rotation frequency of the Kirchhoff point vortex theory. The expansion is then used in the low Mach number Lighthill equation to derive …
