This book was released on 2012 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The environmental and economic impact of fossil fuel generating plants has resulted in the need to find more efficient and clean sources of electricity power generation. As an alternative, promising power generation options such as renewable energy sources, especially wind energy, are receiving increased interest. This dissertation addresses some important problems in power system operations (stability and power quality) when renewable energy resources (generation and storage) are integrated into the conventional power system. In particular, the use of energy storage (STATCOM/Battery) to enhance the small-signal stability, transient stability, and voltage regulation of an electrical power system with renewable power generation is investigated as follows. 1) A linearized model of the nonlinear power system in the region of a steady-state operating point is used in conjunction with an LMI-based control design method, including D-stability, to achieve small-signal angle and frequency stability, voltage regulation, when the system is perturbed by changes in mechanical power inputs to the synchronous generators in the system. 2) A nonlinear model of the power systems with energy storage is used with an Interconnection and Damping Assignment-Passivity-Based Control design (IDA-PBC) framework to achieve transient power angle stability along with frequency and voltage regulation after the occurrence of a large disturbance (a symmetrical three-phase short circuit transmission line fault). 3) Using the combination of the IDA-PBC control law and a reduced-order nonlinear observer, voltage regulation and system stability enhancement are simultaneously accomplished following both temporary and permanent faults. To illustrate the effectiveness of the STATCOM/Battery to enhance small-signal and transient stability, the LMI-based controller design with D-stability and IDA-PBC controller design are validated using the following simulation studies: (1) a single machine infinite bus (SMIB) (2) a two-machine (synchronous generator and doubly-fed induction generator) connected to an infinite bus. For the small-signal case, simulation results show that the proposed controller can simultaneously achieve frequency and voltage regulation along with improved transient performance. For the large-signal case, the results show that the proposed controller provides improved critical clearing times (CCTs) and an enlarged domain of attraction (DOA) along with improved frequency and voltage regulation.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transient stability of a power system depends heavily on its operational state at the moment of a fault. In systems where the penetration of renewable generation is significant, the dispatch of the conventional fleet of synchronous generators is uncertain at the time of dynamic security analysis. Hence, the assessment of transient stability requires the solution of a system of nonlinear ordinary differential equations with unknown initial conditions and inputs. To this end, we set forth a computational framework that relies on Taylor polynomials, where variables are associated with the level of renewable generation. This paper describes the details of the method and illustrates its application on a nine-bus test system.

Download or read book Transient Stability Analysis for Power System Networks with Asynchronous Generation written by Prem Kethavath and published by . This book was released on 2015 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention is increasing on transient stability and secure mode of operation for power systems with asynchronous generation. This is due to asynchronous mode of generation like wind farms, increasing in capacity and displacing existing high inertia synchronous generation. Participation of wind farms, which are primarily inertia decoupled during transient disturbance, will become necessary to comprehensively analyse framework like energy function and coherency based reduction methods. This thesis investigates the impact of reduced system inertia due to asynchronous generation, on transient stability of power systems. This thesis proposes an energy function approach to assess power system transient stability impacts following increased penetration of asynchronous generation plants. The asynchronous wind farm generation is considered as an equivalent conventional synchronous generator with negligible inertia. Assessment has been carried out on single machine infinite system and three machine nine bus test system to compute critical energy and critical fault clearing time, from first principles, using potential energy boundary surface method. A new representation of plotting contours of critical clearing times on inertia space has been developed. This enables estimation of additional inertia required for a system due to inertia reduction from asynchronous generators. The results of the simulation and new graphical method confirms that transient stability margin of the system is impacted with increased penetration of asynchronous generation. This thesis also investigates coherency based analysis technique for network reduction to carry out transient stability analysis for a large power system network that has wind penetration. Identification of coherent groups targets to obtain simplified dynamic equivalent of system by aggregation of coherent generators and replacing it with an equivalent generator. The use of this equivalence can transform a large power system into a reduced model, localized into a small internal area containing the disturbance which impact stability. The New England, 39 bus 10 machine system has been used to demonstrate the methodology. Contingencies are applied with and without wind farm i.e., by replacing few synchronous generators with wind farm of similar capacity. This thesis also develops transient stability enhancement method for networks with asynchronous generation. When a machine inertia is reduced its first swing stability can be enhanced by line series compensation and also multi-swing stability using bang-bang control on series compensation. Compensation values and the lines that can participate in series compensation during contingencies are found.

Download or read book Digital Rubbish written by Jennifer Gabrys and published by University of Michigan Press. This book was released on 2013-04-26 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a study of the material life of information and its devices; of electronic waste in its physical and electronic incarnations; a cultural and material mapping of the spaces where electronics in the form of both hardware and information accumulate, break down, or are stowed away. Where other studies have addressed "digital" technology through a focus on its immateriality or virtual qualities, Gabrys traces the material, spatial, cultural and political infrastructures that enable the emergence and dissolution of these technologies. In the course of her book, she explores five interrelated "spaces" where electronics fall apart: from Silicon Valley to Nasdaq, from containers bound for China to museums and archives that preserve obsolete electronics as cultural artifacts, to the landfill as material repository. Digital Rubbish: A Natural History of Electronics describes the materiality of electronics from a unique perspective, examining the multiple forms of waste that electronics create as evidence of the resources, labor, and imaginaries that are bundled into these machines. Ranging across studies of media and technology, as well as environments, geography, and design, Jennifer Gabrys draws together the far-reaching material and cultural processes that enable the making and breaking of these technologies.
