In the developing countries electrical energy is very important for its all-round improvement by saving thousands of
dollars and investing them in other sector for development. For Growing needs of power existing hierarchical, centrally
controlled grid of the 20th Century is not sufficient. To produce and utilize effective power supply for industries or
people we should have Smarter Electrical grids that address the challenges of the existing power grid. The Smart grid can
be considered as a modern electric power grid infrastructure for enhanced efficiency and reliability through automated
control, high-power converters, modern communications infrastructure along with modern IT services, sensing and
metering technologies, and modern energy management techniques based on the optimization of demand, energy and
network availability and so on. The main objective of this paper is to provide a contemporary look at the current state of
the art in smart grid communications as well as critical issues on smart grid technologies primarily in terms of
information and communication technology (ICT) issues like security, efficiency to communications layer field. In this
paper we propose new model for security in Smart Grid Technology that contains Security Module(SM) along with
DEM which will enhance security in Grid. It is expected that this paper will provide a better understanding of the
technologies, potential advantages and research challenges of the smart grid and provoke interest among the research
community to further explore this promising research area.
