Renewable Energy Resources Penetration within Smart Grid: An Overview

The recent trend of renewable energy resources penetration into the electricity supply mix has put forward more requirements on the power grid for the quality of supply. Integration of distributed generation units into the power grid has increased planning and operational challenges. Considering the above, capacity planning, grid operations, and demand-side management need to be addressed for beneficial integration. This paper presents a detailed study on renewable energy resources (RERs) integration within smart grid (SG). We present the advantages, complexities, issues, and promising solutions for deploying renewables in the SG environment. Our work also analyzes the efficient integration of RERs in an electricity market with enhanced generation capacity, improved power quality, and increased reliability. This paper also reviewed the issues pertaining to the integration of renewables into SG. In addition, a detailed model of SG with integrated renewables is also presented. Moreover, this work provides a perspective view of SG in terms of evolution, economic growth, and barriers to its implementation. Furthermore, technical issues and challenges pertaining to the penetration of RERs within SG are also discussed.
