Dc To Ac Inverter For A Microgrid-Inspired Power Distribution Architecture For Electric Vehicles, Bryan A. Carrillo Martinez, Eli Blacklock, Paul A. Samson, William S. Holt-Hillis
Electrical Engineering
This project builds upon the prototyping of a microgrid-inspired power distribution architecture for electric vehicles (EVs). The efficacy of this prototype aims to inform a full-scale power distribution system that charges an EV battery, supports the electric grid with important ancillary services, performs peer-to-peer EV charging, and works in conjunction with other AC and DC sources and loads. The scope of this report focuses specifically on the design, construction, and testing of the DC/AC inverter. Future development of this distribution architecture will incorporate synchronous generators, a battery management system, and an Arduino/Raspberry Pi-based communication system to fully simulate an electric …
Solar Generation's Impact On Fault Current, Kody Heppner
Solar Generation's Impact On Fault Current, Kody Heppner
Electrical Engineering
California is paving the road for other states with the capacity of solar installations for residential and commercial entities. The added capacity of solar generation to the state's electric grid has an impact on power flow and fault currents. This project looks at the impact of solar installations on fault currents. Feeders with added residential rooftop solar and larger commercial solar installations may impact the system differently than a large, utility-sized solar installation. This project looks at the impact of both cases on the magnitude of fault current during many different fault types and locations that can occur within a …
Solar-Powered Hot Tub, Jonathan Peterson, Anthony Zepeda
Solar-Powered Hot Tub, Jonathan Peterson, Anthony Zepeda
Electrical Engineering
This paper discusses the design and implementation of a solar-powered hot tub. The concept of this project was to design an independently-operated hot tub powered by a 12V rechargeable battery, charged during the day by a single 400W solar panel. For this purpose, a twenty-year-old name-brand hot tub was purchased, in used condition. The plumbing, AC electrical wiring, and mechanical pumps were all removed and replaced with new components to meet our design specifications. Additionally, a solar water-heater was designed and integrated into the system to directly apply the sun’s heat to water pumped in and out of the tub, …
Design And Simulation Of V2g Bidirectional Inverter And Dc-Dc Converter, Allan Agatep, Mason Ung
Design And Simulation Of V2g Bidirectional Inverter And Dc-Dc Converter, Allan Agatep, Mason Ung
Electrical Engineering
As plug-in hybrid electric vehicles (PHEV) become more popular, the utility companies are forced to feed the grid more electricity. However, these PHEVs are capable of providing power to the grid when they are parked serving as ancillary systems for grid regulation (V2G). Using a system based on photovoltaic (PV) technology, a design for a bidirectional inverter with LCL filter, and a bidirectional dc-dc with a constant current controller, was constructed using LTspice. Various papers were researched and analyzed to determine applicable designs for components. Simulations show the designs are capable of bidirectional power transfer. ETAP simulations show that delivering …
