As a result, the possible values of energy storage capacity can be: E = 0, Δ E, 2Δ E, 3Δ E, …, m Δ E; similarly, the possible values of wind power capacity can be: Pwn = 0, Δ P, 2Δ P, 3Δ P, …, n Δ P. m and n limit the maximum value of energy storage capacity and wind power capacity, respectively.
This higher energy storage capacity system is well suited to multihour applications, for example, the 20.5 MWh with a 5.1 MW power capacity is used in order to deliver a 4 h peak shaving energy storage application.
The energy storage capacity of a gravity energy storage system can be scaled up and optimized by using multiple weights.
Combine the energy storage capacity and the wind power capacity, four systems can be obtained as shown in Table 18.2. Table 18.2. The combination of multiple scenarios setting System 1: E = 0, Pwn = 0 represents the conventional system, which does not consider the energy storage and the wind power.
As an example, a multiweight system in a 750 m deep decommissioned coal mineshaft installed with 20 individual 550 t weights would achieve an energy storage capacity of 20.5 MWh. As with the single weight configuration, the power level could then be configured depending on the requirements of the local application.
Yuhong Mo, in Smart Power Distribution Systems, 2019 Denote Δ E and Δ P as the basic unit of energy storage capacity and wind power capacity, respectively.
