6 FAQs about [How to solve the problem of overcapacity of energy storage batteries]

Is excessive energy storage a problem?

Spyros Foteinis highlights the acknowledged problem that an insufficient capacity to store energy can result in generated renewable energy being wasted (Nature 632, 29; 2024). But the risks for power-system security of the converse problem — excessive energy storage — have been mostly overlooked.

Why is energy storage oversupply a problem?

The expansion is driven mainly by local governments and lacks coordination with new energy stations and the power grid. In some regions, a considerable storage oversupply could lead to conflicts in power-dispatch strategies across timescales and jurisdictions, increasing the risk of system instability and large-scale blackouts.

How to solve SoC imbalance problem in battery cells?

In , the battery cells' SOC imbalance issue is solved by automatically adjusting each cell's discharge/charge rate while maintaining a regulated dc bus voltage. However, the energy interaction between the storage units is neglected.

Why is the initial state of charge of a battery inconsistent?

Generally, the battery storage unit's initial state of charge (SOC) is inconsistent , . It is easy for some energy storage units to exit operation prematurely due to energy depletion, leading to the reduction of available capacity and the removal of power supply reliability of the power system , , .

Is excessive energy storage a threat to China's power system?

But the risks for power-system security of the converse problem — excessive energy storage — have been mostly overlooked. China plans to install up to 180 million kilowatts of pumped-storage hydropower capacity by 2030. This is around 3.5 times the current capacity, and equivalent to 8 power plants the size of China’s Three Gorges Dam.

What is energy storage technology?

Energy storage technology allows us to meet demand accordingly by either storing or releasing excess electricity. Through these solutions, energy storage will allow 21 st century society to solve some of the major problems it is currently facing.
