6 FAQs about [Outdoor power supply residual energy]
What is residual load?
Residual load is the remaining electricity demand that renewable energies cannot cover. The graphic below, an example taken from Germany, shows the actual load versus the residual load for August 2022. The upper curve indicates the required load. We can see the demand peak at noon and can easily identify the weekends with less load.
How does the expansion of renewables affect the residual load curve?
The expansion of fluctuating renewables only has a small effect on peak residual load, but leads to a strong decrease of the right- hand side of the residual load curve. In a system without thermal must-run and with flexible biomass generation, residual load becomes negative during 5% of all hours of the year in 2032.
How does residual load affect supply security?
The residual load is directly impacted by this. Only as much electricity being drawn from the system as is fed into it is essential for supply security. If not, grid instabilities happen and smooth electricity transport is challenged. Because of this, there needs to be a constant balance between the input and output of electricity.
How can we reduce surplus energy peaks?
Surplus energies are generally low, but there are high surplus power peaks. Increasing the flexibility of thermal generators substantially reduces surpluses. Allowing curtailment of 1% renders storage investments largely obsolete by 2032. Both storage requirements and the share of seasonal storage increase by 2050. article info
Do fluctuating renewables affect residual load?
In other words, fluctuating renewables substitute a large amount of fossil fuels, but hardly decrease the capacity require ments of the system. These results confirm earlier findings by Ueckerdt et al. (2013) . Fig. 3 also shows the effect of different flexibilityassumptions on residual load.
Does a 20 GW requirement increase surplus energy?
A must-run requirement of 20 GW further increases surplus energy to 28.6 TWh (5%). Decreasing load to 90% or 80% of baseline levels has a similar, but somewhat smaller effect, as 10% of load correspond to a peak load decrease of around 9 GW and an off-peak decrease of only around 4 GW.
