Solar Irradiance Microforecasting, Austin Jeffrey Fite, Sara Naseem Kipps
Solar Irradiance Microforecasting, Austin Jeffrey Fite, Sara Naseem Kipps
Computer Engineering
In late winter quarter 2018 the University of New Mexico and Microgrid Labs provided the Cal Poly Electrical Engineering department with their prototype Solar Irradiance Microforecasting (SIMF) hardware. This hardware was provided to the University under the lone condition that data collected with it would be returned to Microgrid Labs to train their weather model. The goal of this senior project was to take the provided hardware and software and make it usable for students in the Cal Poly Electrical and Computer Engineering departments to hack and expand. The end goal with the hardware is near term cloud and weather …
Power Optimization Of Solar Powered Standalone Wireless Sensor System, Rajan Amatya
Power Optimization Of Solar Powered Standalone Wireless Sensor System, Rajan Amatya
Masters Theses
Wireless sensor systems are common in applications where harsh environmental conditions or remote locations make it difficult to run wires. Having these sensor systems self-powered is essential as it is difficult for battery replacement. Using solar as an alternative source of energy can be a medium to charge the battery in such scenarios. With an increasing number of portable devices powered by battery; more and more research is focused on low-power design technique. For this thesis, a microcontroller (Texas Instruments MSP432) was used along with a digital sensor (Bosch BME280) to provide temperature, pressure and humidity information, and Wi-Fi module …
Application Of Silicon Nanohair Textured P-N Junctions In A Photovoltaic Device, Michael Small
Application Of Silicon Nanohair Textured P-N Junctions In A Photovoltaic Device, Michael Small
Electronic Theses and Dissertations
The goal of this project is to design and develop a fabrication process for a silicon photovoltaic device which incorporates a nanohair textured p-n junction. The silicon nanowires are etched into a silicon wafer, comprising an epitaxial p-layer on n-substrate, via metal-assisted chemical etching (MACE). The resulting nanowires contain p-n junctions that lie along the length of the vertical nanowires. This construct has the potential to increase the optical bandwidth of a silicon photovoltaic device by allowing a greater amount of short wavelength light to reach the junction. In addition, the MACE method of nanofabrication has the potential for decreasing …

Grid-Tied Solar System, Virginia Yan
Electrical Engineering
Distribution level solar energy generation has gained importance and popularity, because it helps create a sustainable electricity system while reducing the harmful environmental impacts our current power systems have. This project proposes an alternative energy source, a laboratory-scale grid-connected photovoltaic system. A KC120-1 solar panel produces 120 Watts maximum. A grid-tied solar power inverter does DC-to-AC conversion and minimizes energy transfer losses. The inverter also has an anti-islanding feature, which senses a power outage and prevents back-feeding through isolating the circuit. The circuit breakers isolate electrical components and protect the circuit. Schweitzer Engineering Laboratories SEL-751 feeder protection relay and SEL-735 …
Multidimensional Optimal Droop Control For Dc Microgrids In Military Applications, Kaitlyn J. Bunker, Michael D. Cook, Wayne Weaver, Gordon Parker
Multidimensional Optimal Droop Control For Dc Microgrids In Military Applications, Kaitlyn J. Bunker, Michael D. Cook, Wayne Weaver, Gordon Parker
Michigan Tech Publications
Reliability is a key consideration when microgrid technology is implemented in military applications. Droop control provides a simple option without requiring communication between microgrid components, increasing the control system reliability. However, traditional droop control does not allow the microgrid to utilize much of the power available from a solar resource. This paper applies an optimal multidimensional droop control strategy for a solar resource connected in a microgrid at a military patrol base. Simulation and hardware-in-the-loop experiments of a sample microgrid show that much more power from the solar resource can be utilized, while maintaining the system’s bus voltage around a …
Analysis Of The Properties Of Supercapacitors And Possible Applications For The Technology, Vincent Oliveto
Analysis Of The Properties Of Supercapacitors And Possible Applications For The Technology, Vincent Oliveto
Honors Theses
Supercapacitors have a lot of excellent qualities that would make them a great substitute for batteries when it comes to electrical energy storage systems. Supercapacitors can discharge and charge very rapidly, they have a lifespan in the realm of millions of cycles, and they are much more efficient than batteries. Unfortunately, they cannot hold nearly as much charge as batteries. This paper seeks to further investigate the properties of supercapacitor technology and the best way to exploit these properties with the purpose of integrating them into renewable energy systems. There is currently a lot of research occurring around the world …

Dc House Solar Panel Cleaner, Sarahanne Heredia, Sophia Deguia
Electrical Engineering
Solar panels lose 0.05% of their power conversion efficiency per day due to soil accumulation, according to an experiment conducted by the University of California, San Diego in 2013 [18]. The project is an electro-mechanical cleaning system that effectively and efficiently cleans solar panels at set intervals. A drip irrigation system with spray jets was attached to a water pump and Arduino, both powered by the DC House Project solar panel battery. The DC House solar panel was the targeted panel set up for the project. Several components of the design could have been chosen more optimally for the system; …

The Eco-Smart Can V2.0, Darack B. Nanto
Appalachian Student Research Forum
I noticed that the workers had the same itinerary when emptying trashcans, meanwhile trashcans needed urgently to be emptied. Traditionally, ETSU maintenance operate on daily routes to pick trash on designated time, regardless the level of the containers. This leads to overflown trashcan in busy areas or during rush hours in certain areas. This overflown trashcan result in an unclean environment for the community and an unpleasant look of our beautiful campus. The time, resources and labor invested in collecting the trash could be saved. Therefore, I decided to use the Internet of Things (IoT) to create a device that …

Developing A 1-Megawatt Photovoltaic Power Plant For Liberty University, Andrew Knudsen
Senior Honors Theses
A photovoltaic power plant with a generation capacity of 1-megawatt is designed for Liberty University. Liberty University’s location and size are stated to provide context for the design. Design choices are presented, first with general information that is applicable to any photovoltaic plant design, then with significant factors that impact this design. Specific models of solar panels and inverters are selected after the necessary classifications are determined. The final design has 2,880 solar panels with a fixed angle 30⁰ above the horizon, has two central inverters, and takes up 2.57 acres. Future research is suggested for finances as well as …
