Distributed Intelligent System for Self-Healing in Smart Grids

Abstract

More and more consumers of electricity demand services with the highest quality standards. One of these standards that have been required is the continuity of services as well as the speedy recovery after a power outage. With the advent of smart grids, the problems of distribution systems are attacked and systemic reliability indexes are improved. It occurs as a result of the automation that has been taking place in these systems. This paper aims to present a contribution in the area of self-healing distribution networks in the event of a permanent short-circuit wherein a systemic reconfiguration is necessary. The proposed strategy, based on distributed intelligence, allows the signals to propagate between the recovery switches, without these switches requiring a large range of communication. It occurs because the sign of a switch broadcasts on the network through communication between adjacent switches to establish an optimized switching solution. This strategy has been tested in a real network and in a large distribution network for simple, sequential, and multiple short-circuits.
