Abstract – Smart Grid is significantly being initiated in all fields due to their extensive use of IT, monitoring, protection, and automation control. Safety, integrity, privacy and dependability of data with long-term sustainability using green sources of energy. Ensuring perfection in their implementation is a herculean task amidst varying environments. This paper sketches and highlights about the scope of implementing reliable, secure, error-controlled fault-tolerant techniques in Electric Grid-systems. Thus, the paper talks about the sub-units of Smart Grid systems. The discussions on opportunities due to nanotechnology and incorporation of FPGAs are part of this paper. Hence, the design of this paper is well thought-out as the critical focal junction in enhancing the future in design of Smart Grid systems.

Human society as a whole, economic needs and innovative technologies has catalyzed the grid revolution. The power grid stands as the autonomous backbone for delivering electricity to consumers that include centralized and distributed power generating infrastructure with varied storage systems ([1], [2]). Information Technologies (ITs) are working on par with traditional energy systems to provide a more reliable quality power from aging infrastructure with lower rates. Ever since fifty-five years ago, electrical power grids were managed and operated in a disconnected manner due to the unavailability of sophisticated software tools. Decisions were being implemented only after manual calculations and findings. The lack of an appropriate system to enhance better cooperation and communication amongst plant operators in making the right decisions had a significant impact. Advances in IT sector, science and engineering in the recent decades can be utilized to bring in a new infrastructure using optimized tools, algorithms, and controllers. It facilitates the decisions to be carried out in short real-time scales to manage the uncertainty and erratic nature of renewable energy, quick fault diagnose to prevent cascading catastrophic effect ([3], [4]).
