This document discusses self-healing in smart grids. It defines self-healing as a smart grid's ability to quickly detect and isolate faults and reconfigure itself to restore normal operations. The document outlines the components of a smart grid that enable self-healing, including sensors, communication infrastructure, control algorithms, and actuators. It also describes the goals of a self-healing system as being reliable, fault-tolerant, and resilient. Tools that can help achieve self-healing are discussed, such as software agents, synchronized phasor measurement units, and information communication technology. Self-healing is explored at the levels of transmission grids, distribution grids, and microgrids.

SELF- HEALING SYSTEM GOALS Reliable systems •Quick and accurate analysis of faults •protect the system from harmful effects Fault-tolerant systems: •When a fault occur the system performance is not affected. •Assuring the continuity of service under any conditions. Resilient system •Minimization of the service's self- renewal period •Reconfigure to cope with disturbances.
