1. Introduction. Thermal energy storage (TES) has been widely adopted in various fields to deal with the intermittency of renewable energy sources and to optimize energy consumption and peak load management (Alem Kebede et al., 2022; Chavan et al., 2022).One of the most promising forms of TES is latent heat storage (LHS), which
This is because, in Brazil (i) the charging time is always very long (21 h), meaning that the BESS requires a limited demand for charging and that the contracted demand in the off-peak period is unlikely to increase significantly, (ii) the discharge time is always of only three hours, meaning that all of the stored energy can be discharged in a
