Power flow control: Solutions for a modern grid [Book review]

This book gives a clear and straightforward introduction to power flow control in complex transmission systems. Starting with basic electrical engineering concepts and theory, the authors provide step-by-step explanations of the modeling techniques of various PFCs, such as the voltage-regulating transformer, the phase angle regulator, and the unified PFC. The book covers the most up-to-date advancements in the Sen transformer, including various forms of two-core designs and hybrid architectures for a wide variety of applications. Beginning with an overview of the origin and development of modern PFCs, the authors explain each topic in straightforward engineering terms— substantiating the theory with appropriate mathematics. Throughout the text, easy-to-understand chapters present characteristic equations of various PFCs, explain modeling in the Electromagnetic Transients Program (EMTP) programming language, compare transformer-based and mechanically switched PFCs, discuss grid congestion and power flow limitations, and more. The book explains why effective PFCs should be viewed as simple impedance regulators. In addition, computer simulation codes of the various PFCs in the EMTP programming language are provided to ease the EMTP simulation for interested readers. Numerous examples and data cases are provided throughout the book to clarify complex issues. Actual power system networks are simulated, and the results are presented. The book introduces the concept of a SMART PFC that is based on functional requirements and cost-effective solutions.
