The optimal energy storage capacities were 729 kWh and 650 kWh under the two scenarios with and without demand response, respectively. It is essential for energy storage to smoothen the load curve of a power system and improve its stability .
The optimal energy storage configuration combinations under three preferences and seven combination scenarios were obtained by solving the influence of unit investment cost, power load, energy storage charging, discharging efficiency, and the proportion of installed RE capacity to the new power capacity of energy storage.
Finding a reasonable capacity configuration of the energy storage equipment is fundamental to the safe, reliable, and economic operation of the integrated system, since it essentially determines the inherent nature of the integrated system .
In the uppermost capacity configuration level, the capacities of energy storage equipment are optimized considering the investment costs and the feedback of operating performance of the entire plant. The candidate capacity is sent to the operation optimization stage as reference device capacities.
Behind the meter energy storage: Installed capacity per country of all energy storage systems in the residential, commercial and industrial infrastructures. The purpose of this database is to give a global view of all energy storage technologies. They are sorted in five categories, depending on the type of energy acting as a reservoir.
The peak year for the maximum newly added power capacity of energy storage differs under different scenarios (Fig. 7 (a)). Under the BAU, H-B-Ma, H-S-Ma, L-S-Ma, and L-S-Mi scenarios, the new power capacity in 2035 will be the largest, ranging from 47.2 GW to 73.6 GW.
