6 FAQs about [Photovoltaic power curtailment and energy storage]

How is PV energy curtailed?

Seuss et al. used the voltage at the point of common coupling (PCC) to estimate PV energy curtailed, where curtailment was performed by ramping down PV active power depending on the voltage measurements in a volt–watt droop .

What is PV curtailment?

With PV curtailment, PV generation is curtailed in the central hours of the day. Table 6. Optimal decisions of ESS sizes and sites for case A (with PV curtailment). Fig. 7 shows the cumulative distribution function (CDF) of all voltages and currents for all the timesteps, scenarios and nodes/lines.

How does PV curtailment affect grid capacity?

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. As a result, PV curtailment is projected to increase as PV composes greater shares of grid capacity ( Denholm et al., 2015 ).

Does storage of PV output eliminate curtailed PV output?

At least some PV output is lost, generally on the order of 20%, when PV is stored and re-dispatched. From a grid perspective, the round-trip efficiency losses associated with storage represent curtailed PV output. Thus storage of PV output cannot fully eliminate curtailment. Published by Elsevier Ltd on behalf of International Solar Energy Society.

Could a curtailment management scheme improve PV output?

A shift in thinking toward curtailment management rather than prevention could increase the value of delivered and curtailed PV output to the grid. Various grid flexibility measures—including flexible generation, storage, load flexibility, and regional coordination—could be key components of a curtailment management scheme.

What is a PV power curtailment algorithm?

A PV power curtailment algorithm is developed to limit PV power when power fluctuation exceeds the power capacity of the HESS. A multi-objective optimization model is established to dispatch the HESS power, considering energy losses and the state of charge (SOC) of the supercapacitor.
