The increasing electricity demand, together sensor networks (WSNs) brings significant advantages over tradi- with the complex and nonlinear nature of the electric power tional communication technologies used in today’s electric power distribution network, have caused serious network congestion systems. Recently, WSNs have been widely recognized as a promis- ing technology that can enhance various aspects of today’s electric issues. The network congestion and safety-related factors have power systems, including generation, delivery, and utilization, become the main causes of several major blackouts that hap- making them a vital component of the next-generation electric pened in recent years. In addition to the overstressed situation, power system, the smart grid. However, harsh and complex elec- the existing power grid also suffers from the lack of perva- tric-power-system environments pose great challenges in the reli- sive and effective communications, monitoring, fault diagnos- ability of WSN communications in smart-grid applications. This paper starts with an overview of the application of WSNs for elec- tics, and automation, which further increase the possibility of tric power systems along with their opportunities and challenges region-wide system breakdown due to the cascading effect and opens up fu
