They also have a major drawback—a risk of damage due to excessive discharge or overcharge. This article studies the process of charging and discharging a battery pack composed of cells with different initial charge levels.
An attempt was made to determine the risk of damage to the cells relative to the differences in the initial charge level of the battery pack cells. It was verified, whether the successive charging and discharging cycles reduce or increase the differences in the amount of energy stored in individual cells of the pack.
Furthermore, the control system provides effective charging of the battery in the micro-grid. In order to achieve the system operation under islanding conditions, a coordinated strategy for the BESS, RES and load management, including load shedding and considering battery SoC and battery power limitation, is proposed.
The battery charging process is simulated in this case. For this purpose, the DC micro-grid is supposed to be connected to an external AC micro-grid, a portion of the demanded load is supplied by the PV and the insufficient power plus the battery charging power is provided by the GS-VSC by means of rectifying the AC power.
