| Summary: | The use of energy in the domestic and industries
lead to the pollution mainly due to the greenhouse gas
emissions as well as pressure to replace the scarce fossil-fuel
based energy. These contribute to the urgency towards the
deployment of Renewable Energy (RE) and concurrently, the
optimization of the existing energy distribution via Smart
Grids (SGs). However, the present SGs implementation is still
in their maturing stages especially in developing countries and
yet to be extensively deployed due to many challenges. One of
them is to develop robust, scalable and secured communication
system between the Distributed Renewable Generations
(DRGs) and the SGs. Improvement in the communication
system definitely will increase the efficiency of both the existing
energy management as well as the feeding system between the
relatively low output DRGs to the SGs. In this paper, first we
discussed DRGs especially solar Photovoltaic (PV) and wind
generations along the suitable areas to mitigate weather
uncertainty. Then a review on communication network
architecture and Energy Management System (EMS) for
integrating DRGs to the grid is presented. A comparison
among the network technologies were also done to determine
the robustness and efficiency of the network communication in
terms of SGs.
