Rural Photovoltaic Energy Storage

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.

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.

Why is energy storage important in PV power generation?

Energy storage can not only alleviate the intermittent and fluctuating problems of PV power generation but also better match power supply and demand and optimize the allocation of power resources (Zhou et al. 2022). During periods of sufficient sunlight and overcapacity in PV power generation, energy storage can store this additional electricity.

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.

Does PV local consumption rate affect centralized energy storage?

With the gradual improvement of PV local consumption rate, we found that the difference in total energy storage capacity between Scenario 2 and Scenario 3 is also gradually increasing, further confirming that as the PV local consumption rate increases, the advantages of storage sharing of centralized energy storage become more significant.

Are rural household PVS a good investment for China?

Rural household PVs have become an important supporting force for China to promote the clean and low-carbon transformation of rural energy and implement the rural revitalization strategy (Li et al. 2024).
