Solar and wind energy may stabilise the power grid https://www.mpg.de/6351135/power-grid-regenerative-energy
A decentralized power grid with many small wind generators, solar generators and other renewable energy transducers along with additional power lines may be less vulnerable to outages than a centralized power grid with a small number of large power plants, because self-synchronization occurs in the former. This finding was made through simulations performed by the research team led by M. Timme at the Max Planck Institute for Dynamics and Self-Organisation. However, they found that it is important for grid stability that new lines are planned with care in order to avoid Braess’s Paradox.
self-synchronizes, it might be assumed that synchronization would become easier with each new link
