Optimization Of Union College’S Microgrid To Meet All Load With A Least-Cost, Low-Carbon Energy Mix, Caitlin Mcmahon Jun 2020

Optimization Of Union College’S Microgrid To Meet All Load With A Least-Cost, Low-Carbon Energy Mix, Caitlin Mcmahon

Honors Theses

A microgrid is a localized electric grid that generates some or all of the power used to meet its load. Union College currently has a microgrid that meets 70 percent of the campus’ load and is connected to the main grid. It is made up of a cogeneration plant as well as solar photovoltaic panels and wind turbines, which are renewable energy sources. The goal of this project is to determine the least cost, low-carbon energy mix that meets 100 percent of the campus’ load. The issue with solar and wind power is that they are variable based on time …


Three-Phase Pulse Width Modulated Ac/Dc Rectifier And Dc/Ac Inverter, Carmen Ngo Jun 2020

Three-Phase Pulse Width Modulated Ac/Dc Rectifier And Dc/Ac Inverter, Carmen Ngo

Honors Theses

Electric vehicles use inverter and rectifier circuits in order to convert power from one type to another. They run on direct current batteries, but their motors can run on direct current (DC) or alternating current (AC). There is a need for both of these circuits if the motor runs on AC. The objective of this project is to successfully replicate driving and braking in an electric vehicle, and understand its power flow. Both systems should start to convert the input power as soon as the source is “on” and should continue this conversion without interruption. In the driving system, a …
