Power grids are losing something that once went largely unnoticed: the physical inertia of large spinning turbines. For decades, that rotational mass acted as a natural buffer against sudden frequency swings. As coal and gas plants are decommissioned, the buffer shrinks \u2014 and grids become markedly more sensitive to any generation-load imbalance. Engineers at ABB have flagged this as one of the defining challenges of the energy transition.<\/p>\n

Historically, grid operators relied on synchronous generators and synchronous compensators to supply inertial mass and regulate voltage. The expectation is now shifting to inverter-based resources, which system operators increasingly require to deliver comparable performance.<\/p>\n

Modern battery converters can work in two distinct modes. The conventional approach treats the inverter as a current source that tracks existing grid voltage \u2014 workable under normal conditions, but unreliable in weak networks where short-circuit capacity and reactive power are limited. Grid-forming mode inverts this logic: the inverter operates as a controlled voltage source, independently establishing local frequency parameters rather than following an external reference.<\/p>\n

That architectural shift opens up capabilities traditionally provided by synchronous plant:<\/p>\n
