Reducing Overvoltage-Induced PV Curtailment Through Reactive …
The battery inverter provides reactive power support to mitigate overvoltage without affecting its active power flow. If the reactive power of the battery inverter is insufficient, the PV inverter response modes are activated. This technique reduces reliance on PV inverters and thus minimizes active power curtailment. The proposed method is ...

Effects of cycling on lithium-ion battery hysteresis and overvoltage
Here we report a direct relationship between an increase in OCV hysteresis and an increase in charge overvoltage when the cells are degraded by cycling. We find that the hysteresis is related to diffusion and increases with the formation of pure phases, being primarily related to the graphite electrode. These findings indicate that the graphite ...
