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.
China's optimal energy storage annual new power capacity is on the rise as a whole, reaching peak capacity from 33.9 GW in 2034 (low GDP growth rate-energy storage maximum continuous discharge time-minimum transmission capacity (L-B-Mi scenario) to 73.6 GW in 2035 (H-S-Ma scenario).
Therefore, under the H-S-Ma scenario of a minimum continuous discharge time and maximum power transmission energy, China's optimal energy storage capacity will grow the fastest, with an average annual growth rate of 17.6%. The larger the power transmission capacity is, the smaller the cumulative power capacity of energy storage.
The annual energy storage capacity planning is determined by synthesizing the energy output of all time slices. It is also a common and mature method in power planning models and is sufficient for the proposed model based on its application in similar models.
Optimal new power capacity and investment for energy storage (2021–2035). The optimal annual investment in China's energy storage initially increased and then decreased under all the scenarios except H-S-Ma, reaching a peak of 4.2 million yuan (L-B-Mi) - 10.7 million yuan (BAU) in 2031 (Fig. 7 (b)).
