the relationship between energy storage charging and discharging and the power grid
Journal of Energy Storage
The energy storage battery undergoes repeated charge and discharge cycles from 5:00 to 10:00 and 15:00 to 18:00 to mitigate the fluctuations in photovoltaic (PV) power. The high power output from 10:00 to 15:00 requires a high voltage tolerance level of the transmission line, thereby increasing the construction cost of the regional grid.
