This study presents a capacity optimization model for building energy storage systems that incorporates the building energy flexibility requirement, measured by the load shifting capacity ratio (LSCR), to minimize the net present cost (NPC).
The energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.
Similarly, Kallio et al. improved the thermal reliability from 0.48 to 0.67 and the electrical reliability from 0.02 to 0.7 by applying thermal energy storage (TES), battery energy storage (BES), and an electric boiler while optimizing system operation. Energy storage is an essential technology for managing building energy flexibility .
To enable a consistent comparison of the optimization results for PV-TES, PV-BES, and PV-HES systems, as well as to assess the impact of COP on energy storage capacity optimization, the coefficient of performance for heating (COP h) and cooling (COP c) are 4.12 and 3.99, respectively, according to Ref .
