Grid Integration
Grid integration of renewable energy, especially wind energy, is a controversial topic–and has been for nearly three decades. Frankly, I think the subject has been beaten to death and for my part the questions answered many times over. Nevertheless, those opposed to renewable energy continually raise the subject in the hopes that this is some silver bullet that will put wind and solar energy in its grave. As a consequence, renewable energy advocates ask me for help to rebut the common myths about wind energy’s “unreliability”. For this reason, I occasionally post articles or reports on the topic of grid integration.
Wind Generation Also Good Match with Peak Demand Says Northern Power

Why power generators are terrified of solar

Giles Parkinson, Of Reneweconomy
Here is a pair of graphs that demonstrate most vividly the merit order effect and the impact that solar is having on electricity prices in Germany; and why utilities there and elsewhere are desperate to try to rein in the growth of solar PV in Europe. . .
Energy & Environmental Science: The carbon abatement potential of high penetration intermittent renewables
By
At very high penetrations, combining wind and solar power improved renewable portfolio performance over individual build-out scenarios by reducing curtailment, suggesting that further reductions may be met by importing uncorrelated out-of-state renewable power. The results also suggest that 90–100% carbon emission reductions will rely on the development of demand response and energy storage facilities with power capacities of at least 65% of peak demand and energy capacities large enough to accommodate seasonal energy storage. . .

Merit Order Effect: Impact of Wind Generation on Wholesale Electricity Costs in 2011 in Ireland
By
Dr. Eoin Clifford (eirgrid)
“The analysis showed that wind generation lowers wholesale prices by over €70 million, which almost exactly offsets the costs of the Public Service Obligation (PSO) levy and other costs associated with the generation of wind energy. The study clearly demonstrates that wind energy is not contributing to higher wholesale electricity prices on the Irish electricity system. . .”
