Distributed generation is becoming increasingly prevalent on power grids around the world. Conventional designs and grid operations are not always sufficient for handling the implementation of distributed generation units; the new generation may result in undesirable operating conditions, or system failure. This paper investigates the primary issue...

The Electric Bicycle System is a systems project that incorporates three different ways of charging a lithium-ion battery: the 120VAC wall outlet, regenerative braking, and solar power; which is used to power an electric hub motor running a bicycle. The purpose of the project is to show that it is possible and relatively simple, to build an electri...
This study focuses on the potential applications for printed batteries and how they could affect the printing industry. It also analyzes the main problems associated with manufacturing this technology and what needs to be done to overcome these issues. To find the answers to these questions, two methods of research were used. The first was through ...
This report documents the design phases and fabrication of an expandable micro-motor DC drive system. This project illustrates that a flexible range of output power demands can be met from a small DC micro-motor drive unit with the use of power electronics. In this project miniature DC micromotor drives, each capable of drawing up to 5.5 amps rated...
Given a good model and implementation of that model, computer simulation can be used to reduce the time and material costs of research. To this end I worked with other students to manufacture, test and simulate the single layer P3HT-PCBM solar cell. Using the data collected from this project, future work can then be done with the project's simulato...
The purpose of this senior project was to design and fabricate a proof-of-concept Three-Phase Sinusoidal Switched-Mode Inverter with a power output capability of 10 kW and nominal operating frequency of 400 Hz for AC aircraft system applications. This senior project report includes a thorough discussion and presentation of the inverter system backg...
As Cal Poly moves towards an environmentally friendly campus, the Energy Harvesting from Exercise Machines (EHFEM) project looks to generate a new source of renewable energy to help power the Cal Poly Recreation Center. The project focuses on retrofitting exercise machines to generate electricity. As of December 2009, Audrey Nakamura, Justin Arakak...
Today’s electric utilities are confronted with a myriad of challenges that include aging infrastructure, enhanced expectation of reliability, reduced cost, and coping effectively with uncertainties and changing regulation requirements. Utilities rely on Asset Management programs to manage inspections and maintenance activities in order to control e...
An electronic converter is designed for an isolated renewable energy system. In this system, energy produced by a small wind turbine is used to extract hydrogen from water. Unique aspects of this application that affect the performance of the converter will be defined. Design considerations of the individual components will be discussed. Calculatio...
California is experiencing a rapid increase in interest for the potential of converting ocean waves into clean electricity. Numerous applications have been submitted for the permitting of such renewable energy projects; however the profitability, practicability, and survivability have yet to be proven. Wave energy conversion technology has steadily...
