Flexible AC Transmission Systems (FACTS) devices are revolutionizing the way we manage and control electrical power systems. These innovative technologies offer a wide range of benefits, including improved stability, increased efficiency, and enhanced reliability. By implementing optimal control schemes, utilities can harness the full potential of FACTS devices to address complex grid challenges and ensure a more resilient and efficient power grid.

This article presents a collection of real-world case studies that demonstrate the practical applications and benefits of FACTS devices. These case studies showcase how utilities have successfully implemented FACTS devices to solve specific grid challenges, such as:

Improving voltage stability
Reducing power losses
Enhancing transient stability
Increasing transmission capacity
Mitigating harmonics

Through these case studies, we will explore the different types of FACTS devices, their operating principles, and the control schemes that are used to optimize their performance. We will also discuss the challenges that utilities face when implementing FACTS devices and the strategies that they have employed to overcome these challenges.

Case Study: Improving Voltage Stability with SVCs

A major utility in the United States installed a Static Var Compensator (SVC) to improve voltage stability on a critical transmission line. The SVC was able to quickly and effectively regulate the voltage on the line, which prevented voltage collapse and ensured the reliable delivery of power to customers.

The SVC was installed at a substation located at the midpoint of the transmission line. The SVC consisted of a capacitor bank, a reactor bank, and a thyristor-controlled voltage source converter (VSC). The VSC was used to control the flow of reactive power between the capacitor bank and the reactor bank, which allowed the SVC to rapidly adjust the voltage on the line.

The implementation of the SVC resulted in a significant improvement in voltage stability on the transmission line. The SVC was able to maintain the voltage within acceptable limits during both normal and contingency conditions. This improved voltage stability reduced the risk of voltage collapse and ensured the reliable delivery of power to customers.

Case Study: Reducing Power Losses with STATCOMs

A large electric utility in Europe installed a Static Synchronous Compensator (STATCOM) to reduce power losses on a heavily loaded transmission line. The STATCOM was able to reduce power losses by up to 10%, which resulted in significant cost savings for the utility.

The STATCOM was installed at a substation located at the end of the transmission line. The STATCOM consisted of a voltage source converter (VSC) and a capacitor bank. The VSC was used to control the flow of reactive power between the capacitor bank and the transmission line, which allowed the STATCOM to regulate the voltage and reduce power losses.

The implementation of the STATCOM resulted in a significant reduction in power losses on the transmission line. The STATCOM was able to reduce power losses by up to 10%, which resulted in annual cost savings of over $1 million for the utility.

Case Study: Enhancing Transient Stability with HVDCs

A large electric utility in South America installed a High-Voltage Direct Current (HVDC) transmission system to enhance transient stability on a critical transmission corridor. The HVDC system was able to quickly and effectively transfer power between two regions, which improved transient stability and prevented blackouts.

The HVDC system consisted of two converter stations, one located at each end of the transmission corridor. The converter stations converted AC power to DC power and back, which allowed the HVDC system to transmit power over long distances with low losses.

The implementation of the HVDC system resulted in a significant improvement in transient stability on the transmission corridor. The HVDC system was able to quickly transfer power between the two regions, which prevented blackouts and ensured the reliable delivery of power to customers.

The case studies presented in this article demonstrate the practical applications and benefits of FACTS devices in power systems. By implementing optimal control schemes, utilities can harness the full potential of FACTS devices to solve complex grid challenges and ensure a more resilient and efficient power grid.

FACTS devices are a powerful tool that can be used to improve voltage stability, reduce power losses, enhance transient stability, increase transmission capacity, and mitigate harmonics. As the power grid continues to evolve, FACTS devices will play an increasingly important role in ensuring the reliable delivery of power to customers.
