The role of storage in managing the variability in wind, solar and wave energy generation is well understood. Shifting energy from periods of high generation to low generation is seen as an ideal role for storage. However, the rapid fluctuations in wind and solar generation with periods less than 1 h can lead to very significant problems on the grid, reducing carrying capacity of lines and increasing the amount of spinning reserve and regulation services required to unachievable levels. A number of electrical storage technologies which are aimed at removing these rapid fluctuations are now being successfully demonstrated at the MW-scale. The various storage technologies are outlined and an example of wind smoothing system is examined in detail.
