Although the majority of recent electricity storage system installations have a duration at rated power of up to ∼4 h, several trends and potential applications are identified that require electricity storage with longer durations of 10 to ∼100 h.
The optimal size of energy storages is determined with respect to nodal power balance and load duration curve. Most of these papers, however, address the optimal storage sizing problem with respect to the hourly wind power fluctuations and uncertainties.
Apower is defined similarly, (9) A power = W power / c ¯ where Wpower represents the actual power rating. The value of Apower is generally 0–5. Furthermore, the energy storage duration hdur (h), namely the ratio of capacity to power, characterizes different energy storage technologies .
In the electricity market, global and continuing goals are CO 2 reduction and more effi cient and reliable electricity supply and use. The IEC is convinced that electrical energy storage will be indispensable to reaching these public policy goals.
There are many applications for electricity storage: from rechargeable batteries in small appliances to large hydroelectric dams, used for grid-scale electricity storage. They differ in the amount of energy that has to be stored and the rate (power) at which it has to be transferred in and out of the storage system.
Energy storage systems are among the technologies that can be effectively employed to facilitate the wind power integration into electric power systems [6, 7]. Storage can absorb excess wind power output and inject power to the system when the wind power generation is less than the amount needed.
