Converter-Based Dynamics and Control of Modern Power Systems addresses the ongoing changes and challenges in rotating masses of synchronous generators, which are transforming dynamics of the electrical system.

These changes make it more important to consider and understand the role of power electronic systems and their characteristics in shaping the subtleties of the grid and this book fills that knowledge gap.

Balancing theory, discussion, diagrams, mathematics, and data, this reference provides the information needed to acquire a thorough overview of resilience issues and frequency definition and estimation in modern power systems.

This book offers an overview of classical power system dynamics and identifies ways of establishing future challenges and how they can be considered at a global level to overcome potential problems. The book is designed to prepare future engineers for operating a system that will be driven by electronics and less by electromechanical systems.

Includes theory on the emerging topic of electrical grids based on power electronics Creates a good bridge between traditional theory and modern theory to support researchers and engineers Links the two fields of power systems and power electronics in electrical engineering

The book provides a comprehensive taxonomy of non-symmetrical eigenvalues problems as applied to power systems. The book bases all formulations on mathematical concept of “matrix pencils” (MPs) and considers both regular and singular MPs for the eigenvalue problems. Each eigenvalue problem is illustrated with a variety of examples based on electrical circuits and/or power system models and controllers and related data are provided in the appendices of the book. Numerical methods for the solution of all considered eigenvalue problems are discussed. The focus is on large scale problems and, hence, attention is dedicated to the performance and scalability of the methods. The target of the book are researchers and graduated students in Electrical & Computer Science Engineering, both taught and research Master programmes as well as PhD programmes and it:explains eigenvalue problems applied into electrical power systemsexplains numerical examples on applying the mathematical methods, into studying small signal stability problems of realistic and large electrical power systemsincludes detailed and in-depth analysis including non-linear and other advanced aspectsprovides theoretical understanding and advanced numerical techniques essential for secure operation of power systemsprovides a comprehensive set of illustrative examples that support theoretical discussions

Frequency Variations in Power Systems: Modeling, State Estimation and Control presents the Frequency Divider Formula (FDF); a unique approach that defines, calculates and estimates the frequency in electrical energy systems. This authoritative book is written by two noted researchers on the topic. They define the meaning of frequency of an electrical quantity (such as voltage and current) in non-stationary conditions (for example the frequency is not equal to the nominal one) and pose the foundation of the frequency divider formula. The book describes the consequences of using a variable frequency in power system modelling and simulations, in state estimation and frequency control applications.In addition, the authors include a discussion on the applications of the frequency divider in systems where part of the generation is not based on synchronous machines, but rather on converter-interfaced energy resources, such as wind and solar power plants. This important book: Offers a review that clearly defines and shows how the Frequency Divider Formula can be appliedDiscusses the link between frequency and energy in power systemsPresents a unified vision that accurately reveals the common thread that links modelling, control and estimationIncludes information on the many implications that “local frequency variations” have on power system dynamics and controlContains several numerical examplesWritten for researchers, academic staff members, students, specialised consultants and professional software developers, Frequency Variations in Power Systems questions the conventional transient stability model of power system and proposes a new formulation.

Advances in Power System Modelling, Control and Stability Analysis captures the variety of new methodologies and technologies that are changing the way modern electric power systems are modelled, simulated and operated.The book is divided into three parts. Part 1 presents research works on power system modelling and includes applications of telegrapher equations, power flow analysis with inclusion of uncertainty, discrete Fourier transformation and stochastic differential equations. Part 2 focuses on power system operation and control and presents insights on optimal power flow, real-time control and state estimation techniques. Finally, Part 3 describes advances in the stability analysis of power systems and covers voltage stability, transient stability, time delays, and limit cycles.A rich mix of theoretical aspects with practical considerations, as well as benchmarks test systems and real-world applications makes this book essential reading for researchers and students in academia and industry in electric power systems modelling and control.

Power systems are becoming increasingly complex as well as flexible, able to integrate distributed renewable generation, EV, and additional loads. This expanded and updated second edition covers the technologies needed to operate modern power grids.Initial chapters cover power system modelling, telegrapher equations, power flow analysis, discrete Fourier transformation and stochastic differential equations. Ensuing chapters deal with power system operation and control, power flow, real-time control and state estimation techniques for distribution systems as well as shipboard systems. The final chapters describe stability analysis of power systems and cover voltage stability, transient stability, time delays, and limit cycles. New content for the second edition includes four new chapters on recent modelling, control and stability analysis of power electronic converters and electric vehicles.This new edition is an essential guide to technologies for operating modern flexible power systems for PhD students, early-career researchers and practitioners in the field.

This book explains frequency quality in a comprehensive and systematic way. It does so by combining theoretical and practical knowledge on the topic. It includes dynamic simulations and real-world examples. For example, the book discusses the frequency performance of large-scale real-world power systems such as the Irish, UK, and Australian power systems. The book also presents a comprehensive analysis of the impact of different electricity market models, different control parameters, microgrids, topology, and converter-based demand on frequency quality. Then, the book provides an in-depth description of industry practice when it comes to frequency reserves dimensioning approaches and monitoring and reporting of frequency quality. The authors also clarify many terms related to frequency control and commonly used by the power system community.The book serves as a reference for engineers working for transmission system operators as well as researchers studying the topic of frequency quality and control and the challenges of modern power systems with high shares of converter-interfaced generation and demand.

Power system modelling and scripting is a quite general and ambitious title. Of course, to embrace all existing aspects of power system modelling would lead to an encyclopedia and would be likely an impossible task. Thus, the book focuses on a subset of power system models based on the following assumptions: (i) devices are modelled as a set of nonlinear differential algebraic equations, (ii) all alternate-current devices are operating in three-phase balanced fundamental frequency, and (iii) the time frame of the dynamics of interest ranges from tenths to tens of seconds. These assumptions basically restrict the analysis to transient stability phenomena and generator controls. The modelling step is not self-sufficient. Mathematical models have to be translated into computerprogramming code in order to be analyzed, understood and “experienced”. It is an object of the book to provide a general framework for a power system analysis software tool and hints for filling up this framework with versatile programming code.This book is for all students and researchers that are looking for a quick reference on power system models or need some guidelines for starting the challenging adventure of writing their own code.
