the main challenge for the electrical power system is a provident storehouse technology. An energy storehouse is essential for the unborn Smart Grid (SG) to smooth out the shifting affair of Renewable Energy coffers (RERs). Indeed though numerous good storehouse technologies are available either they aren't provident or they aren't effective. Several exploration studies have anatomized the operation of energy storehouses with respect to voltage support, peak paring, frequency stability, renewable indurate, transmission upgrade postponement, and a host of other uses. RERs are dependent on the climate conditions for the power affair. thus, an effective storehouse technology is an important part of the trust ability of electric power systems. This paper compares different storehouse technologies available, hydrogen storehouse, batteries, superconducting attraction energy storehouse, fly bus, compressed air energy storehouse, pumped hydro energy storehouse, etc. This paper details the necessity of storehouse ways to help the RERs power affair in the SG to meet the energy demands of the future.
