Framework For Assessing Stability Challenges In Future Converter Dominated Power Networks

The dynamics of operation of both machines are well understood, including potential stability issues. With the introduction of converter-interfaced generation, power networks are becoming diverse systems, associated with which is an increased number of stability issues to consider.

This book offers a comprehensive assessment of the stability of modern power systems through advanced nonlinear analysis frameworks. It addresses the new challenges to power system stability posed by the anticipated integration of numerous power-electronic interface devices needed to support renewable energy generation. Given the diverse operational timescales associated with controllers for power electronic-interfaced devices, these devices can have an impact on a wide range of dynamic phenomena, thereby significantly influencing the system's dynamic performance and stability. The methodologies presented effectively manage the significant changes in system dynamics introduced by these devices.. This research utilizes nonlinear methodologies, specifically bifurcation theory, to analyse various stability types in such power-electronic-rich systems. The book adopts a bifurcation-based methodology to evaluate power system stability through detailed examination of each type of instability mechanism. The methodology developed is extended to explore the interactions between multiple types of system stability considering the impacts of different voltage-source-converter controllers and grid strengths. Finally, to reduce the high computational burden imposed by the proposed methodology, a hybrid network model is developed to assess the system stability efficiently. Stability Assessment of Power Systems with Multiple Voltage Source Converters is of interest to students, researchers, and industry professionals in the field of electrical engineering.

The understanding of power system voltage stability has become increasingly important due to day by day increase in electricity demand and liberalization policy of electricity markets. Therefore, voltage stability has become significantly important during the past decades. Both voltage stability formulation and indices are covered in this book along with an easily comprehensible manner and detailed exposition of the voltage stability indices' fundamental. However, the content of this book is considered serviceable in advanced level. The author combines his knowledge with reporting of accurate update information to illustrate the voltage stability indices and compared how to distinguish numbers of these indices in view of theirs similarity, functionality, applicability, formulation, merit, demerit, and overall performances. This book will serve as a valuable guide for the typical reader. That the readers had in mind were researchers, engineers, planners, and other professionals involved in the assessment of voltage instability in electric power system. The prerequisite for this book is suggested the basic knowledge of power system analysis and voltage stability subjects. The authorship methodology of this book had been based on the reference book style.

Singular perturbation is used to derive and explain reduced-order models.

Grid converters are the key player in renewable energy integration. The high penetration of renewable energy systems is calling for new more stringent grid requirements. As a consequence, the grid converters should be able to exhibit advanced functions like: dynamic control of active and reactive power, operation within a wide range of voltage and frequency, voltage ride-through capability, reactive current injection during faults, grid services support. This book explains the topologies, modulation and control of grid converters for both photovoltaic and wind power applications. In addition to power electronics, this book focuses on the specific applications in photovoltaic wind power systems where grid condition is an essential factor. With a review of the most recent grid requirements for photovoltaic and wind power systems, the book discusses these other relevant issues: modern grid inverter topologies for photovoltaic and wind turbines islanding detection methods for photovoltaic systems synchronization techniques based on second order generalized integrators (SOGI) advanced synchronization techniques with robust operation under grid unbalance condition grid filter design and active damping techniques power control under grid fault conditions, considering both positive and negative sequences Grid Converters for Photovoltaic and Wind Power Systems is intended as a coursebook for graduated students with a background in electrical engineering and also for professionals in the evolving renewable energy industry. For people from academia interested in adopting the course, a set of slides is available for download from the website. www.wiley.com/go/grid_converters
