With the challenges associated with global climate change, the "low-carbon economy" based on low energy consumption, low pollution, and low emissions has become a frequently debated topic on a global scale, which places further emphasis on the need to develop higher requirements for safely operating power systems. State estimation or situational awareness, as well as protection technologies, are key technological products that can acquire, understand, display, and predict future development trends of factors that can cause changes in a system in a large-scale environment. It has been applied in many fields such as power energy, aerospace, etc. New power systems have diverse application scenarios, complex operating conditions, and strong safety constraints. Therefore, how to apply situational awareness and protection technologies to adapt to different scenarios and ensure the reliable, safe, high-quality, low-carbon, and economic operation of new power systems has become an important topic of research within the field. This Reprint focuses on the development of state estimation, situational awareness, and protection technologies of power systems. It aims to lay a foundation for the low-carbon economic and safe operation of new power systems.
