Book Robust Stability Analysis for Large scale Power Systems

Download or read book Robust Stability Analysis for Large scale Power Systems written by Richard Yi Zhang and published by . This book was released on 2017 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Innovations in electric power systems, such as renewable energy, demand-side participation, and electric vehicles, are all expected to increase variability and uncertainty, making stability verification more challenging. This thesis extends the technique of robust stability analysis to large-scale electric power systems under uncertainty. In the first part of this thesis, we examine the use of the technique to solve real problems faced by grid operators. We present two case studies: small-signal stability for distributed renewables on the IEEE 118-bus test system, and large-signal stability for a microgrid system. In each case study, we show that robust stability analysis can be used to compute stability margins for entire collections of uncertain scenarios. In the second part of this thesis, we develop scalable algorithms to solve robust stability analysis problems on large-scale power systems. We use preconditioned iterative methods to solve the Newton direction computation in the interior-point method, in order to avoid the O(n6) time complexity associated with a dense-matrix approach. The per-iteration costs of the iterative methods are reduced to O(n3) through a hierarchical block-diagonal-plus-low-rank structure in the data matrices. We provide evidence that the methods converge to an [epsilon]-accurate solution in O(1=[square root of ] [epsilon]) iterations, and characterize two broad classes of problems for which the enhanced convergence is guaranteed.

Book Power System Operation with Large Scale Stochastic Wind Power Integration

This book was released on 2016-09-17 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the uncertainties of wind power modeled as interval numbers and assesses the physical modeling and methods for interval power flow, interval economic dispatch and interval robust economic dispatch. In particular, the optimization models are set up to address these topics and the state-of-the-art methods are employed to efficiently solve the proposed models. Several standard IEEE test systems as well as real-world large-scale Polish power systems have been tested to verify the effectiveness of the proposed models and methods. These methods can be further applied to other research fields that are involved with uncertainty.

Book Intelligent Systems for Stability Assessment and Control of Smart Power Grids

Download or read book Intelligent Systems for Stability Assessment and Control of Smart Power Grids written by Yan Xu and published by CRC Press. This book was released on 2020-12-10 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power systems are evolving towards the Smart Grid paradigm, featured by large-scale integration of renewable energy resources, e.g. wind and solar power, deeper participation of demand side, and enhanced interaction with electric vehicles. While these emerging elements are inherently stochastic in nature, they are creating a challenge to the system’s stability and its control. In this context, conventional analysis tools are becoming less effective, and necessitate the use alternative tools that are able to deal with the high uncertainty and variability in the smart grid. Smart Grid initiatives have facilitated wide-spread deployment of advanced sensing and communication infrastructure, e.g. phasor measurement units at grid level and smart meters at household level, which collect tremendous amount of data in various time and space scales. How to fully utilize the data and extract useful knowledge from them, is of great importance and value to support the advanced stability assessment and control of the smart grid. The intelligent system strategy has been identified as an effective approach to meet the above needs. This book presents the cutting-edge intelligent system techniques and their applications for stability assessment and control of power systems. The major topics covered in this book are: Intelligent system design and algorithms for on-line stability assessment, which aims to use steady-state operating variables to achieve fast stability assessment for credible contingencies. Intelligent system design and algorithms for preventive stability control, which aims at transparent and interpretable decision-making on preventive control actions to manipulate system operating condition against possible contingencies. Intelligent system design and algorithms for real-time stability prediction, which aims to use synchronized measurements to foresee the stability status under an ongoing disturbance. Intelligent system design and algorithms for emergency stability control, which aims at fast decision-making on stability control actions at emergency stage where instability is propagating. Methodologies and algorithms for improving the robustness of intelligent systems against missing-data issues. This book is a reference and guide for researchers, students, and engineers who seek to study and design intelligent systems to resolve stability assessment and control problems in the smart grid age.

Book Cyberphysical Infrastructures in Power Systems

Download or read book Cyberphysical Infrastructures in Power Systems written by Magdi S. Mahmoud and published by Academic Press. This book was released on 2021-10-23 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an uncertain and complex environment, to ensure secure and stable operations of large-scale power systems is one of the biggest challenges that power engineers have to address today. Traditionally, power system operations and decision-making in controls are based on power system computations of physical models describing the behavior of power systems. Largely, physical models are constructed according to some assumptions and simplifications, and such is the case with power system models. However, the complexity of power system stability problems, along with the system's inherent uncertainties and nonlinearities, can result in models that are impractical or inaccurate. This calls for adaptive or deep-learning algorithms to significantly improve current control schemes that solve decision and control problems. Cyberphysical Infrastructures in Power Systems: Architectures and Vulnerabilities provides an extensive overview of CPS concepts and infrastructures in power systems with a focus on the current state-of-the-art research in this field. Detailed classifications are pursued highlighting existing solutions, problems, and developments in this area. Gathers the theoretical preliminaries and fundamental issues related to CPS architectures. Provides coherent results in adopting control and communication methodologies to critically examine problems in various units within smart power systems and microgrid systems. Presents advanced analysis under cyberphysical attacks and develops resilient control strategies to guarantee safe operation at various power levels.

Book Power System Dynamic and Stability Issues in Modern Power Systems Facing Energy Transition

Download or read book Power System Dynamic and Stability Issues in Modern Power Systems Facing Energy Transition written by Cosimo Pisani and published by Mdpi AG. This book was released on 2022-12-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic stability basically deals with the interactions between the system's components. Following a disturbance, the system's variables undergo transitions that can induce oscillations in active and reactive power generation, resulting in the occurrence of voltage oscillatory modes and frequency deviation in the system. Depending on the entity of the disturbance, the small- or large-signal stability of the system under consideration can be investigated. The introduction of RES-based generation that does not participate in the network services (i.e., frequency and voltage regulation) due to lack of special controls will undoubtedly affect both the overall frequency and voltage stability. Large-scale transient stability is also a concern not to be overlooked: inverter-based wind and solar generation have different angle/speed swing behaviors with respect to traditional generation due to reduced inertia, different voltage swing behaviors due to different voltage control systems, different power flow patterns, and different displacements of synchronous generation at key locations. Therefore, although power system stability and dynamics have played a very central role in the management and study of electrical power systems thus far, it is also true that the emerging scenario requires new methodologies, technologies, and analyses. In this light, the current Special Issue aims to collect contributions (i.e., research papers and review articles) on power system dynamics and stability from experts in academia and industry.

Book Robust Stability and Performance Analysis of Large Scale Power Systems with Parametric Uncertainty

Download or read book Robust Stability and Performance Analysis of Large Scale Power Systems with Parametric Uncertainty written by Rafael B. Castellanos and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the application of new techniques based on multivariable control theory and optimisation theory to the study of robust stability of highly uncertain models of large interconnected power systems subject to real parameter variations. It focuses on the study of robust stability problems associated with parameter variations representing real physical quantities. The objective is to verify that critical system controllers of complex systems remain stable and achieve desired performance objectives for all predefined power system variations at selected operating conditions along its expected operating trajectory. A second related objective is to determine the stability robustness with respect to changes in power system parameters and the maximum loading condition for which the system will remain stable.

Book Dynamic Stability Analysis of Large scale Power Systems Using a Fast Investigation Method

Download or read book Dynamic Stability Analysis of Large scale Power Systems Using a Fast Investigation Method written by Ming-Tse Kuo and published by . This book was released on 2006 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following power market deregulation and the proposed standard market design, the activities of cross boundary power transactions are increased significantly. Traditional company based stability analysis can not satisfy today's operating environment. However, simulating the entire interconnection power system may exceed the capacity of existing commercial stability analysis software. Fortunately, most of the stability problems are started from the local level. One will be able to avoid most of the system wide stability issues by mitigating the problems in the early stage. Based on eigenvector decompositions of the Jacobian, this dissertation proposes a new algorithm for performing the dynamic stability problem for a large interconnected power system. Using Python and MATLAB to build an integrated simulation environment around PSS/E not only overcomes the large-scale power system problem but also shortens the simulation time. The proposed method has been verified on the Southwest Power Pool (SPP) system, which has close to 30,000 buses. The simulation results on both the proposed approach and the entire system were almost identical.
