The Internet of Things (IoT) is playing an important role in providing access to affordable

clean and green energy worldwide through the use of smart devices. The current electric power networks will be more reliable

secure

flexible and durable by implementing IoT in power systems. This paper presents a brief discussion about IoT contributions in the development of power systems from a generation

transmission

distribution and consumption point of view. 5G cellular networks have a great potential for the development of IoT technology. Additionally

5G cellular networks can be instrumental in supporting the greater communication needs of IoT. This review provides a comprehensive analysis about the role of 5G cellular networks in the growth of IoT technology and power systems. Large amounts of data will be generated due to the incorporation of renewable energy

deployment of the smart grid and the improvements to the electricity market. In this way

in order to realize the connection between things and people

things and things and people and people in power systems

it is essential to apply IoT in power systems. In this case

5G is providing numerous advantages to Power IoT (PIoT) by offering greater opportunities in progress and improvements; however

there are also numerous challenges with the deployment of 5G in PIoT. Finally

this review article provides an overview of the role

implications and challenges of 5G in PIoT.
