Book Description

The extended and revised second edition of this successful monograph presents advanced modeling, analysis and control techniques of Flexible AC Transmission Systems (FACTS). The book covers comprehensively a range of power-system control problems: from steady-state voltage and power flow control, to voltage and reactive power control, to voltage stability control, to small signal stability control using FACTS controllers. In the six years since the first edition of the book has been published research on the FACTS has continued to flourish while renewable energy has developed into a mature and booming global green business. The second edition reflects the new developments in converter configuration, smart grid technologies, super power grid developments worldwide, new approaches for FACTS control design, new controllers for distribution system control, and power electronic controllers in wind generation operation and control. The latest trends of VSC-HVDC with multilevel architecture have been included and four completely new chapters have been added devoted to Multi-Agent Systems for Coordinated Control of FACTS-devices, Power System Stability Control using FACTS with Multiple Operating Points, Control of a Looping Device in a Distribution System, and Power Electronic Control for Wind Generation.

Book Description

The objective of this research is to investigate the performance enhancement of a power system using Flexible AC Transmission System (FACTS) devices. It is intended to show how the reliability and performance of the power system is improved. The focus is to enhance the understanding of the system operating with and without these devices. Power transmission can always be improved by upgrading or adding new transmission circuits. But this is not a practical solution. FACTS devices are feasible alternatives for optimizing the transmission systems. Providing reactive shunt compensation with shuntconnected capacitors and reactors is a well-established technique to get a better voltage profile in a power system. Shunt capacitors lack dynamic capabilities, and so dynamically controlled reactive power compensation is essential. This feature is provided by FACTS devices. Implementation of new equipment consisting high power electronics based technologies such as FACTS becomes essential for improvement of operation and control of power systems. FACTS promote the use of static controllers to enhance the controllability and increase the power transfer capability. Three software tools were used in this thesis, such as, MATLAB, PSCAD and PowerWorld. Thyristor Controlled Reactors (TCR), Thyristor Controlled Series Capacitors (TCSC), Static Var Compensators (SVC) are used as FACTS devices for consideration in the power system study. This thesis aims at examining the ability of FACTS devices and distributed FACTS devices for power flow control and reactive power compensation in a power system.

Book Description

The emerging technology of Flexible AC Transmission System (FACTS) enables planning and operation of power systems at minimum costs, without compromising security. This is based on modern high power electronic systems that provide fast controllability to ensure 'flexible' operation under changing system conditions. This book presents a comprehensive treatment of the subject by discussing the operating principles, mathematical models, control design and issues that affect the applications. The concepts are explained often with illustrative examples and case studies. In particular, the book presents an in-depth coverage of: Applications of SVC, TCSC, GCSC, SPST, STATCOM, SSSC, UPFC, IPFC and IPC for voltage/power control in transmission systems; Application of DSTATCOM, DVR and UPQC for improving power quality in distribution systems; Design of Power Oscillation Damping (POD) controllers; Discrete control of FACTS for improving transient stability; Mitigation of SSR using series FACTS Controllers; Issues affecting control design such as electromagnetic and harmonic interactions. The book can serve as a text or reference for a course on FACTS Controllers. It will also benefit researchers and practicing engineers who wish to understand and apply FACTS technology.
