Oversupply of energy storage inverters [PDF]

6 FAQs about [Oversupply of energy storage inverters]

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.

Can inverters help grid operators withhold PV output?

In the technological context, emerging inverters may allow grid operators to control PV output to provide a variety of grid services such as capacity reserves and frequency regulation.

How does PV oversupply impact the grid?

As more Photovoltaic (PV) is integrated onto the grid, oversupply risk increases (Denholm et al., 2016, Nelson et al., 2018).. Each marginal unit of PV output pushes down the midday net load, making it more likely that PV output will exceed the grid’s ability to absorb that output during the solar peak.

How will storage technology affect electricity systems?

Because storage technologies will have the ability to substitute for or complement essentially all other elements of a power system, including generation, transmission, and demand response, these tools will be critical to electricity system designers, operators, and regulators in the future.

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.
