What are the power constraints for energy storage?
This means the rated power of the energy storage should be capable of meeting the maximum power requirement in the T period, independent of the charging state, to achieve an active power balance. Therefore, the power constraints for energy-type, hybrid-type, and power-type storage are as follows:
What is the optimal electricity storage power and energy capacity?
The optimal electricity storage power and energy capacity as well as the E/P ratio are relatively low in the 60% case. Note that electricity storage does not completely take up the renewable surplus in a least-cost solution; a sizeable fraction is also curtailed, as investments in both storage energy and power incur costs.
