It depends on where you live so I’ll speak about the US.
One of the challenges we have, which you’ve alluded to in your question, is the point of common connection (PCC)—where power from all of the turbines in the wind farm come together and connect to the grid. The utility has to impose a cap on the size of the wind farm based on how much energy can be connected at that single point on a transmission line that was designed more than 100 years ago. In some cases, this cap is fairly meager and it restricts the size of the wind farm.

Nevertheless, whatever the utility’s cap is, the PCC becomes a very expensive substation and a single point for failure in the system. Having one single point where the power is introduced to the grid increases the problem with variability due to fluctuations in wind speed. A change in wind speed of 5 m/s can have a big impact on the grid at the PCC.
A very expensive substation for the PCC and a single point for failure
Germany has largely solved for this problem by distributing their turbines. Driving around Germany you’ll rarely see more than 10 turbines in one location. But you see small clusters—as few as two or three in a cluster—virtually everywhere you go. These small clusters connect directly to the grid at their location and the power is consumed within a small radius from the turbine cluster.
Germany deploys small clusters of turbines connected directly to the grid, without a substation, and the power is consumed locally
Germany’s approach is smart. They don’t require huge expensive substations at the PCC. Since the power is locally consumed they don’t lose energy from transmission line inefficiency. To me it seems like a more sensible system.
