The analysis of a coordinated design approach that combines a proportional-integral-derivative (PID) controller and a unified power flow controller (UPFC)-based stabilizer.The book could explore how this approach can improve power system stability, enhance power quality, and optimize power flow control. It may also discuss the challenges associated with implementing this coordinated design approach and how these challenges can be addressed. Overall, the book could provide insights into the effectiveness of this approach in practical power systems and how it can be applied to enhance the overall performance of the power system.
