Undoubtedly, self-healing is one of the main abilities of the smart grids with respect to traditional systems to automatically retrieve system after fault occurrence or keep away system from critical conditions. Self-healing usually consists of three steps: fault location, isolation and system restoration (FLISR).
The proposed strategy encompasses generation re-dispatch, network reconfiguration, and load shedding. The microgrid self-healing problem is formulated as a mixed-integer quadratic programming problem, which provides a globally optimal solution to facilitate smooth islanding of the microgrid.
The availability of renewable generation in the microgrid has significant impacts on the islanding strategy and different scenarios need to be considered. This study proposes a comprehensive microgrid self-healing strategy under different circumstances.
By appearance of smart grids and developing its level of intelligence, it is possible to automatically detect a fault in the shortest time, isolate it from the system and feed healthy parts of the system on a different path. The set of automatic activities that occur after a fault occurrence to achieve previous goals is called self-healing.
