Five-Level Flying Capacitor Converter Used As A Static Compensator For Current Unbalances In Three-Phase Distribution Systems, Rafael Franceschi

Graduate Theses and Dissertations

This thesis presents and evaluates a solution for unbalanced current loading in three-phase distribution systems. The proposed solution uses the flying capacitor multilevel converter as its main topology for an application known as Unbalanced Current Static Compensator. The fundamental theory, controller design and prototype construction will be presented along with the experimental results. The Unbalanced Current Static Compensator main objective is the balancing of the up-stream currents from the installation point to eliminate the negative- and zero-sequence currents originated by unbalanced single-phase loads.

Three separate single-phase flying capacitor converters are controlled independently using a d-q rotating reference frame algorithm to …

Análisis De Estabilidad De Una Microrred Conectada A Un Sistema De Potencia Convencional, Manuel Alberto Silva Rios, Nicolas Trujillo Alfaro

Ingeniería Eléctrica

En este documento se analiza la estabilidad transitoria y de tensión, para una Microrred que incluye Fuentes No Convencionales de Energía Renovable (FNCER). En el sistema de pruebas seleccionado, realice estudios de caso donde puede variar el funcionamiento del sistema por medio de software especializado en sistemas de potencia, en el cual se modela el sistema eléctrico en estudio, para modificar el comportamiento del mismo, contingencias y salidas de operación de los generadores del sistema, como también la viabilidad de mantener conectadas o no la Microrred. Adicional a esto desde la perspectiva de la normativa vigente en Colombia, consulte las …

Application Of Microgrids In Supporting The Utility Grid, Alireza Majzoobi

Electronic Theses and Dissertations

Distributed renewable energy resources have attracted significant attention in recent years due to the falling cost of the renewable energy technology, extensive federal and state incentives, and the application in improving load-point reliability. This growing proliferation, however, is changing the traditional consumption load curves by adding considerable levels of variability and further challenging the electricity supply-demand balance. In this dissertation, the application of microgrids in effectively capturing the distribution network net load variability, caused primarily by the prosumers, is investigated. Microgrids provide a viable and localized solution to this challenge while removing the need for costly investments by the electric …

A Study On Distributed Generation With A Focus On Solar Power, Shravan Kumar Tomar

Electronic Theses and Dissertations

Centralized generation is when electric power is produced in a large scale of tens of MWs and is located away from the end user. This kind of production is connected to a series of high-voltage transmission lines. Electricity is then delivered to the end user through a network of distribution grids. Centralized generation tend to have multiple end user with multiple user profiles.

Distributed Generation is when is produced in a small scale and is located at the site of or very close to the end user. There are many ways distributed generation can be achieved, Solar power being the …
