This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power electronics is the key technology for connecting flexible ac transmission system devices and renewable power generation to the ac grid. Among the ac to ac converters, the matrix converter represents a promising alternative power electronics technology to back to back converters. It does not incorporate any storage elements which minimises the size and weight of the converter. In addition, with the introduction of the reverse blocking insulated gate bipolar transistor, its efficiency can surpass that of back to back converters. A new approach in controlling the matrix converter output current is introduced. The approach depends mainly on logic circuitry and facilitates power system applications using the matrix converter. Furthermore, it can provide sinusoidal output current under asymmetry voltage conditions. The output current quality is at the expense of the input current in this case. Both sinusoidal input and output currents cannot be achieved under asymmetry voltage conditions due to the lack of any storage elements. Matrix converter suitability to power system applications such as flexible ac transmission and embedded generation, is investigated particularly under asymmetrical ac supply conditions. The effect of the absence of an intermediate storage element, on the output power and current quality is considered. The utilization of the proposed control technique in a unified power flow controller, which is the most versatile flexible ac transmission system device, is investigated. The restriction on unified power flow controller operation due to the absence of any intermediate storage element in the matrix converter is also studied. Special attention is given to asymmetry ac voltage condition effects and how to mitigate this problem for embedded generation. Extraction of the positive and negative sequence components is essential in obtaining non-oscillatory output power, and a dual current controller is used to this end.

Download or read book Indirect Matrix Converter as Standard Power Electronic Interface written by Andres Escobar Mejia and published by . This book was released on 2014 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increase in the penetration levels of distributed generation in the modern power grid and its importance in future energy systems have accelerated the interest of developing new power electronic interfaces for the energy conversion process. The feasibility of applying the indirect matrix converter as the standard power electronic interface for applications with power ratings from several kW to few MW is addressed in this dissertation. Special attention is given to those applications where space dominates the power electronic requirements. The main motivation for using the indirect matrix converter is that eliminates the energy storage component in the way of a dc-link capacitor for the energy conversion process. This contributes to reduce size and weight, and potentially, increase reliability of the power electronic interface. Two main new contributions are presented. First, a new power electronic interface that allows the connection of two ac power grids through a medium- or high-voltage dc system is proposed. The new topology contemplates the use of two high-voltage dc-link converters based on the modular multilevel converter, two indirect matrix converters and two medium-frequency transformers. Second, a new sensorless control technique working in the d -- q reference is developed. The controller is used to interface a distributed generation unit to the power grid when the indirect matrix converter is used as the power electronic interface. The design and performance of the proposed power electronic interface is validated through time-domain simulations and a laboratory prototype is built to experimentally validate the sensorless controller.

Available in PDF, EPUB and Kindle. Book excerpt: This text is an introduction to the use of control in distributed power generation. It shows the reader how reliable control can be achieved so as to realize the potential of small networks of diverse energy sources, either singly or in coordination, for meeting concerns of energy cost, energy security and environmental protection. The book demonstrates how such microgrids, interconnecting groups of generating units and loads within a local area, can be an effective means of balancing electrical supply and demand. It takes advantage of the ability to connect and disconnect microgrids from the main body of the power grid to give flexibility in response to special events, planned or unplanned. In order to capture the main opportunities for expanding the power grid and to present the plethora of associated open problems in control theory Control and Optimization of Distributed Generation Systems is organized to treat three key themes, namely: system architecture and integration; modelling and analysis; and communications and control. Each chapter makes use of examples and simulations and appropriate problems to help the reader study. Tools helpful to the reader in accessing the mathematical analysis presented within the main body of the book are given in an appendix. Control and Optimization of Distributed Generation Systems will enable readers new to the field of distributed power generation and networked control, whether experienced academic migrating from another field or graduate student beginning a research career, to familiarize themselves with the important points of the control and regulation of microgrids. It will also be useful for practising power engineers wishing to keep abreast of changes in power grids necessitated by the diversification of generating methods.
