Technical FAQs 4

How can energy storage help a household PV system?

By contrast, configuring energy storage for household PV can significantly improve this situation. Configuring energy storage can promote the consumption of PV power locally and effectively reduce the pressure of PV grid connection on the power grid system.

Does Household PV centralized energy storage improve power self-balancing capability?

The results show that configuring energy storage for household PV can significantly improve the power self-balancing capability. When meeting the same PV local consumption, household PV centralized energy storage can achieve smaller energy storage configuration and lower cost compared to household PV distributed energy storage.

What is discarded solar PV?

Residential loads and energy storage batteries consume PV power to the most extent. If there is still remaining PV power after the energy storage is fully charged, it is considered as the discarded solar PV. When the PV output is insufficient, the energy storage battery supplies power to the residential loads.

What happens if a rural PV system is not equipped with energy storage?

The results show that: When the rural household PV system is not equipped with energy storage, the PV local consumption rate is 34.58%, and 65.42% of PV power still has to be connected to the grid for consumption, posing a threat to the safe and stable operation of the distribution network.
