Adaptive protection systems

Definition

Adaptive protection systems are advanced technology solutions designed to enhance the reliability and safety of electrical networks by dynamically adjusting their protective settings based on real-time system conditions. These systems ensure that microgrids can operate safely during faults or disturbances, such as when islanding occurs, by continuously monitoring and adapting to changes in generation, load, and grid status. This adaptability helps maintain stability and optimizes the operation of microgrids in various scenarios, ensuring effective fault detection and isolation.
