Calculating the Need for Energy Storage
Two factors need calculating: power (GW) and energy (GWh). It is easiest and clearest to calculate them separately and for the longest low-generation period forecastable – i.e. the kalte Dunkelflaute.

Considering the flexible potential and cost factors, the capacity of energy storage equipment can be reasonably determined in accordance with SSES and SES. The capacity of electricity storage equipment is closely related to the installed capacity of a renewable energy system.
The capacity of electricity storage equipment is closely related to the installed capacity of a renewable energy system. Presenting a PV power generation system as an example, the installed capacity of PV power generation and the storage capacity of the battery must match each other.
Under the MPFPH situation, the minimum electricity storage capacity can ensure the maximum flexible potential during the peak period of electricity consumption. Moreover, storage capacity is relatively large, and thus, it can also prevent the occurrence of the light abandonment phenomenon.
In the PLDP case, the minimum electricity storage capacity is only used to prevent the occurrence of the light abandonment phenomenon. Even if a small amount of power flexibility is provided under certain circumstances, then the magnitude of this power flexibility cannot affect the electricity storage capacity.
In addition, the capacity of heat storage equipment is directly related to the number of energy storage times. For example, the energy storage equipment is required to have a large capacity to store the cold/heat required for 1 day at one time (single-stage energy storage, SSES) during the valley power consumption period.
For the analysis of energy storage parameters, a methodology was adopted assuming that the volatility of energy prices in a year in particular years results in slight changes in the optimal parameters of the energy storage.
