To stipulate modernization in the sustainable energy sector there is a necessity to deregulate the power sector. microgrid allows to maintain the power quality by supplying it through renewable energy sources (RES) mainly involving the interventions through power electronics. The usefulness of devices of power electronics are that they stimulate the heterogeneous loads, stores energy in devices and integrate various forms of RES. The smart grid has made a transition from the conventional grid to a grid which is more modernized that functions responsively and cooperatively. To achieve an economically feasible, to secure and an efficient supply, the consumers, generators and the users may be judiciously integrated with respect to the grid. The benefits of SG are it fosters sustainability, reliability, improves efficiency in the systems involving power flows. According to the National Institute of Standards and Technology (NIST) the smart grids are classified into seven parts which comprises of applications and actors. Actors consist of data-exchange, stakeholders, programs, control systems, smart meters and other devices. This paper deals with the structures of smart grid; technologies associated with it. The various technologies which can be included here are the Demand Side Management (DSM), Wide Area Management System (WAMS), System of outage Management, System pertaining to geographical information. It also explains the advantages of transformation of the smart-grid, the components of smart grid and smart grid data management. The article concludes by stating that there is a great need for renewable sources of energy involving smart grids. There are two factors which limit the usage of grids, one is its variability and the other one is the limited usage of those resources. Hence, there is a need for addressing this widespread usage. Now, the systems in the electric power, has been linked to smart grid. Thus, there is a necessity for alternative renewable sources of energy. This would benefit the developers and the policy makers; also, for the practitioners as well.
