Wireless sensor network in smart grid technology: Challenges and opportunities

The collaborative and low-cost nature of wireless sensor networks (WSNs) brings significant advantages over traditional communication technologies used in today´s electric power systems. Recently, WSNs have been widely recognized as a promising technology that can enhance various aspects of today´s electric power systems, including generation, delivery, and utilization, making them a vital component of the next-generation electric power system, the smart grid. However, harsh and complex electric- power-system environments pose great challenges in the reliability of WSN communications in smart grid applications. This paper starts with an overview of the application of WSNs for electric power systems along with their opportunities and challenges and opens up future work in many unexploited research areas in diverse smart-grid applications.
