Renewable energy resources for electric power generation have got the spotlight by industry and academia as greenhouse effect has become more severe. Micro Grid is an isolated power system that has generators and power loads. For isolated area Micro Grid is an ideal power system for generating electrical power with renewable energy resources like the solar and wind energy. However generations with renewable energy resources cannot meet the demand of loads securely. So smart applications with communication infrastructure are required to control and monitor the power system. The communication infrastructure for smart power grid can be classified as Home Area network (HAN), Neighborhood Area Network (NAN) and Wide Area Network (WAN). Many technologies including cellular network and PLC are competing for communication in Micro Grid. This paper provides discussion of power line communication technologies for Micro Grid.
