This book was released on 2016 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The amount of renewable energy and distributed generation is increasing in the distribution network and is changing the network from passive to active. IEEE is currently revising the interconnection Standard 1547 and in its project P1547 it is anticipated that the new version will include ride through requirements for distributed generation to enhance the stability of the system. Extending existing Wind and PV models with next generation controls evaluate the effectiveness of these new requirements. The extended PV model is added to an IEEE 34-node test feeder and the active distribution network’s fault response is compared to the WECC simplified model for distributed PV system used for bulk system stability studies. It was found the draft IEEE P1547 ride-through requirements increase the amount of PV systems that remain connected post fault. The parameters of the WECC simplified model for distributed PV systems are optimized to match the results from the IEEE-34 node test system with distributed PV. This allows the active distribution system to be simplified for bulk system stability studies and improves the computational performance.

Download or read book Control and Automation of Electrical Power Distribution Systems written by James Northcote-Green and published by CRC Press. This book was released on 2017-12-19 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Implementing the automation of electric distribution networks, from simple remote control to the application of software-based decision tools, requires many considerations, such as assessing costs, selecting the control infrastructure type and automation level, deciding on the ambition level, and justifying the solution through a business case. Control and Automation of Electric Power Distribution Systems addresses all of these issues to aid you in resolving automation problems and improving the management of your distribution network. Bringing together automation concepts as they apply to utility distribution systems, this volume presents the theoretical and practical details of a control and automation solution for the entire distribution system of substations and feeders. The fundamentals of this solution include depth of control, boundaries of control responsibility, stages of automation, automation intensity levels, and automated device preparedness. To meet specific performance goals, the authors discuss distribution planning, performance calculations, and protection to facilitate the selection of the primary device, associated secondary control, and fault indicators. The book also provides two case studies that illustrate the business case for distribution automation (DA) and methods for calculating benefits, including the assessment of crew time savings. As utilities strive for better economies, DA, along with other tools described in this volume, help to achieve improved management of the distribution network. Using Control and Automation of Electric Power Distribution Systems, you can embark on the automation solution best suited for your needs.

Download or read book An Asset-based Interconnection Paradigm for Distribution System Energy Resources written by Allison Esther Auld and published by . This book was released on 2010 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: While distributed energy resources (DER) may provide benefits to the user, environment, and electric utility, the fundamental paradigm for connection with the existing electric system is unknown. To determine the relevant challenges and opportunities associated with this interconnection, the impact of DER on the electric distribution system is assessed through theory, simulation in Matlab/Simulink, and experiment. In all aspects, DER addition without control can result in nuisance behavior such as harmonics, sags, overvoltages, and increased system stress. Yet proper attention, control, and communication can avoid these conditions and even improve system characteristics, thus enabling the DER to become a system asset. The generator-load interaction is simulated by combining measured data from the built environment with a dynamic fuel cell model. An active power filter (APF) capability is deemed necessary at the interconnection because the inverter follows the voltage and does not provide current harmonics directly. With APF and energy storage, the connection can exhibit ideal behavior from all perspectives. When the source and generator-load bus are separated by a line, the inverter-APF can additionally prevent voltage sags and harmonics. This benefit is observed experimentally by combining several common non-linear loads with an APF. The effect of DER on an entire distribution circuit is simulated by adding generation to four sample distribution circuits that each capture behavior found in existing systems. The effects vary with location, but overvoltages can occur with generation as low as 10% of the rated circuit load. Existing local control strategies, such as local voltage regulation (LVR) and real power curtailment can avoid many of these overvoltages, but neither control strategy addresses all of the challenges. The location-based effect of DER can be predicted be linearizing its impact into a voltage change potential (VCP) associated with those circuit parameters. The VCP linearization well captures the modeled behavior of the circuit and is used to create a VCP-based control strategy, which provides voltage regulation for all cases. With additional communication, other functions such as reactive power support, voltage support, capacitor protection, and sharing between multiple DER can be implemented.

Download or read book Modelling, Control and Stability Analysis of Photovoltaic Systems in Power System Dynamic Studies written by Gustav Lammert and published by kassel university press GmbH. This book was released on 2019 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the impact of: i) the low voltage ride-through and dynamic voltage support capability; ii) the active current recovery rate; iii) the local voltage control; and iv) the plant-level voltage control of large-scale photovoltaic systems on short-term voltage stability and fault-induced delayed voltage recovery as well as transient and frequency stability. The power system dynamic performance is analysed using state-of-the-art methods, such as phasor mode time-domain simulations and the calculation of the critical clearing time that determines the stability margin. Moreover, the recently developed Kullback-Leibler divergence measure is applied to assess the quality of the voltage recovery. Drawbacks of this metric are outlined and a novel metric, the so-called voltage recovery index, is defined that quantifies the delayed voltage recovery more systematically. The studies are performed with a generic photovoltaic system model and typical model parameters are used that were determined in collaboration with a manufacturer. The stability analysis is performed in DIgSILENT PowerFactory using: i) a one-load infinite-bus system; and ii) an IEEE multi-machine voltage stability test system, namely the Nordic test system. The results show that with the adequate control of photovoltaic systems, power system dynamic performance can be significantly improved.

Available in PDF, EPUB and Kindle. Book excerpt: The contributions of a diverse selection of international hardware and software specialists are assimilated in this book's exploration of the development of massively parallel processing (MPP). The emphasis is placed on industrial applications and collaboration with users and suppliers from within the industrial community consolidates the scope of the publication. From a practical point of view, massively parallel data processing is a vital step to further innovation in all areas where large amounts of data must be processed in parallel or in a distributed manner, e.g. fluid dynamics, meteorology, seismics, molecular engineering, image processing, parallel data base processing. MPP technology can make the speed of computation higher and substantially reduce the computational costs. However, to achieve these features, the MPP software has to be developed further to create user-friendly programming systems and to become transparent for present-day computer software. Application of novel electro-optic components and devices is continuing and will be a key for much more general and powerful architectures. Vanishing of communication hardware limitations will result in the elimination of programming bottlenecks in parallel data processing. Standardization of the functional characteristics of a programming model of massively parallel computers will become established. Then efficient programming environments can be developed. The result will be a widespread use of massively parallel processing systems in many areas of application.
