A Discussion of the Communication Technologies in Smart Grid

Biao Wang


With an increasing number of distributed renewable energy sources and higher requirements on the efficiency, reliability and security of existing power grid, Smart Grid is regarded as a significant evolution to the electric system. This paper mainly discusses the communication technologies applied in power grid from two aspects: cable technology and wireless technology. The former, such as DSL and PLC, is expensive, but it has broad deployment capability, strong communication capability, reliability and security. The latter could save the cost of installation, but it has limitation on bandwidth and security problems. In the future, grid features, system architecture, critical components, pilot projects of smart grid and its application and challenges after integrating with information and communication technology will be further discussed.
