Self-healing of electric distribution networks: A review

Currently in our society, a constant supply of electric power is assumed, and it is difficult to imagine a day without it. Because of this, the correct and reliable operation of the electrical networks is paramount. This paper presents a literature review of the self-healing techniques applied to the electric distribution networks. Special emphasis has been taken on the different control architectures used in the search of a system with self-regeneration and self-adaptation capabilities in the face of contingencies of the electrical distribution system. In addition, the current validation techniques of a self-healing network are described and classified. Finally, a summary of the self-healing techniques and its main aspects is presented, along with a list of new lines of research.
