The storage material energy storage capacity (ESCmat) is calculated according to the type of TES technology: i. ESCmat for sensible = heat · TES . . Eq. 4 cp.mat: Specific heat of the material [J·kg-1·K-1]. Mmaterial: mass of the storage material [kg]. ∆Tsys: Design temperature difference of the system [K].
The calculation method of annual operation and maintenance cost of energy storage is as follows: (21) = + where kPO is annual operation and maintenance cost of energy storage unit power, kEO is annual operation and maintenance cost of energy storage unit capacity.
In order to comprehensively consider the impact of the energy storage life on the system income, it is also converted into the annual equivalent recovery amount, and the calculation formulas are as follows: (22) f R = σ × k P P B k E E B × SFF (23) SFF = 1 − 1 where σ is equipment residual value residual rate, SFF is sinking-fund factor.
Definition: The energy storage capacity of the system (ESCsys) calculates the total amount of heat that can be absorbed during charging under nominal conditions. The energy is mainly stored in the material; however, some set-ups may contain components in contact with the material, which inevitably heat up, hence storing sensible heat.
Thermal energy is stored solely through a change of temperature of the storage medium. The capacity of a storage system is defi ned by the specifi c heat capacity and the mass of the medium used. Latent heat storage is accomplished by using phase change materials (PCMs) as storage media.
