Energy And Economic Losses Due To Soiling On Utility Scale Pv Systems To Guide Timing Of Cost Effective Cleaning, Jackson P. Puckett, Maximilian M. Sosa, Brandon F. Grossman Jun 2020

Energy And Economic Losses Due To Soiling On Utility Scale Pv Systems To Guide Timing Of Cost Effective Cleaning, Jackson P. Puckett, Maximilian M. Sosa, Brandon F. Grossman

Electrical Engineering

The energy and associated economic losses due to soiling on both residential and utility scale PV (photovoltaic) systems can be both significant and avoidable. Losses from 1.2% up to 6% have been reported, which is of interest to system operators [1]. Modules may be cleaned to reduce losses, but this comes with an offsetting economic cost. A quantification of energy losses, and the corresponding economic loss, will allow a determination of a closer to optimal cleaning schedule depending on the level of soiling and corresponding energy loss. Two methods are proposed and compared. Method 1 uses an ARES Soiling Measurement …


An Integrated Resource Plan For Arizona Public Service Electric (Aps), Irene Boghdadi, Randy Chiu May 2020

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 …


Dual-Axis Solar Tracker, Bryan Kennedy Jan 2020

Dual-Axis Solar Tracker, Bryan Kennedy

All Undergraduate Projects

Renewable energies, and fuels that are not fossil fuel-based, are one of the prolific topics of debate in modern society. With climate change now becoming a primary focus for scientists and innovators of today, one of the areas for the largest amount of potential and growth is that of the capturing and utilization of Solar Energy. This method involves using a mechanical system to track the progression of the sun as it traverses the sky throughout the day. A dual-axis solar tracker such as the one designed and built for this project, can follow the sun both azimuthally and in …


Análisis De Operación De Un Sistema De Generación Undimotriz Conectado A Un Modelo De Red, Juan Sebastián Reyes Salazar Jan 2020

Análisis De Operación De Un Sistema De Generación Undimotriz Conectado A Un Modelo De Red, Juan Sebastián Reyes Salazar

Ingeniería Eléctrica

El uso de generación eléctrica basada en fuentes no convencionales de energía se ha impulsado en los últimos años, una razón de la diversificación de la matriz energética en todos los países del mundo y además con la intención de reducir las emisiones de gases de efecto invernadero. Dentro de su diversidad, las energías renovables cuentan con el movimiento Mareo-Motriz, como función del movimiento ondulatorio de las olas. En este tipo de fuentes no convencionales la emisión de gases de efecto invernadero es prácticamente cero, en la producción de energía este es un paso fundamental que se articula con algunas …


Enabling Innovation In The Energy System Transition, Bonnie Wylie Pratt Jan 2020

Enabling Innovation In The Energy System Transition, Bonnie Wylie Pratt

Graduate College Dissertations and Theses

Innovation in the electric sector has the potential to drive job growth, decrease environmental impacts, reduce rate payer costs, and increase reliability and resiliency. However, the traditional electric system was built to deliver a controlled flow of energy from a centralized location with maximum reliability and minimum cost. As both customer expectations and generation technologies change, new avenues for grid innovation are being explored. Residential customers, commercial and industrial clients, and electric utilities must all find a way to balance goals for decarbonization and social justice with maintaining a least cost, reliable power grid. Grounded in Geel’s energy system transition …
