Abstract: The sources like Wind and Solar engage largest share among different RES to fulfill the demand of clean energy from renewable energy sources (RES). This paper provides an insight of grid integrating issues related with both solar and wind tie ups with different stages of ac-ac, ac-dc, dc-dc, dc-ac conversion. The Converters came into the picture at different levels for integrating of RES with grid for solution to interface arises several issues like an inertia, voltage problem, Frequency Variation, Flicker, Power Factor, Reactive power demand, and Harmonics etc. Inertia deficiency is one of the major issues which affect the overall system dynamics. Control techniques for solar and wind integrating issues are also suggested to tackle the challenges and for future research work suggests VSG as a solution for inertia problem.
