A voltage-shifting-based state-of-charge balancing control for

When the output power of RESs cannot meet the load demand, the BEUs discharge and provide energy to the system. Or, when the output power of RESs exceeds the power demand of load, the BEUs charge to absorb the redundant energy in the system. Therefore, BEUs play a role in regulating bus voltage and energy management.

Comparison of centralised and distributed battery energy storage

The assumption made here is that all the houses installing an RES system (PV) also implement a BES system to locally store part of the energy that was used to be feed into the utility grid, and get paid from feed-in tariff and reduced utility bills by the BES supply to any domestic electricity demand or EV charging.
