The profile of a single generating station can't be projected onto a networked grid. The article below specifically tests wind, but the current grid also performs this way with it's variety of generating sources. The grid is vast and the flowing body of the electricity pool in the grid wires is a product of innumerable fluctuating inputs and withdrawals that precisely resembles in its entirety none of the individual generating sources. So the characteristics of any one system are automatically mitigated by the a sort harmonic coalescing of the individual units into a larger whole.
This lessens the importance of any one specific technological generating niche - including storage.
It is precisely that same design feature of the grid that negates the claims that large-scale thermal "baseload" generating sources are needed. This "baseload" characteristic is greatly over-valued on the technical side by many that are unaware that the fundamental value of "baseload" is an economic product of a centralized system, not an overall technical prerequisite to electric supply in a modern industrial society.

Electric power from offshore wind via synoptic-scale interconnection
Abstract:
World wind power resources are abundant, but their utilization could be limited because wind fluctuates rather than providing steady power. We hypothesize that wind power output could be stabilized if wind generators were located in a meteorologically designed configuration and electrically connected. Based on 5 yr of wind data from 11 meteorological stations, distributed over a 2,500 km extent along the U.S. East Coast, power output for each hour at each site is calculated. Each individual wind power generation site exhibits the expected power ups and downs. But when we simulate a power line connecting them, called here the Atlantic Transmission Grid, the output from the entire set of generators rarely reaches either low or full power, and power changes slowly.
Notably, during the 5-yr study period, the amount of power shifted up and down but never stopped. This finding is explained by examining in detail the high and low output periods, using reanalysis data to show the weather phenomena responsible for steady production and for the occasional periods of low power. We conclude with suggested institutions appropriate to create and manage the power system analyzed here.
From the body of the paper:
Leveling Wind Fluctuations. The variability of wind power is not as problematic as is often supposed, since the electric power system is set up to adjust to fluctuating loads and unexpected failures of generation or transmission. However, as wind power becomes a higher proportion of all generation, it will become more difficult for electric system operators to effectively integrate additional fluctuating power output. Thus, solutions that reduce power fluctuations are important if wind is to displace significant amounts of carbon-emitting energy sources.
There are four near-term ways to level wind power and other fluctuating generation sources.
(i) Expand the use of existing control mechanisms already set up to handle fluctuating load and unexpected equipment outages—mechanisms such as reserve generators, redundant power line routes, and ancillary service markets. This is how wind is integrated today (5).
(ii) Build energy storage, as part of the wind facility or in another central location.
(iii) Make use of distributed storage in loads, for example home heaters with thermal mass added or plug-in cars that can charge when the wind blows or even discharge to the grid during wind lulls (6).
(iv) Combine remote wind farms via electrical transmission, the subject of this article...
