Nowadays, smart grid technologies make use of wireless sensor network (WSN) in electric power generation, transmission and distribution systems. This paper proposes emperor penguin optimised self-healing (EPOSH) strategy for sensor network based smart grid system. Self-healing is a process of automatically detecting and correcting faulted sensor nodes to enable uninterrupted power supply in smart grid systems. In proposed work, data generated from various nodes are forward to cluster leader and routed to base station from leader node. Routing performed based on EPOSH in proposed work which greatly reduces design complexity of self-healing process. Because, EPOSH works in an iterative manner to detect, eliminate faulty nodes and to find optimal alterative solution for routing with faulty nodes. Proposed EPOSH for SG networks implemented in Matlab working environment and resultant performances are compared with existing works such as AEC, GHS, GA-TBR and IGRC.
