Grid scale batteries provide an effective solution.

When Musk sold the first of them to South Australian state power 
generation system, about half the capacity - some 60 mega Watt.hours - 
was devoted to stabilitising the grid phase, which it did brilliantly.

Fast-acting inverters kept the phase right on a cycle to cycle basis. 
The fees it got for performing the service made the grid scale battery a 
very profitable investment. The old grid-stabilising hardware was retired.
