When the battery storage systems all temporarily pause providing grid inertia due to the state of charge check they’re performing, grid synchronized spinning mass has to compensate, which slows it down (transferring the kinetic energy to electrical energy), and then is sped back up as battery storage resumes inertia support. Broadly speaking, it’s a collective momentum problem. If part of the system inertia sags, another part needs to step in to compensate for the inertia loss, otherwise you have brownouts and eventually, a blackout. | ||
