As the world accelerates toward net-zero goals, renewable energy is taking center stage. But with rapid decommissioning of fossil fuel plants, maintaining grid stability has become increasingly complex.

The grid stability challenges

Renewable energy growth

Wind and solar power are expanding rapidly, but their variable nature creates new challenges for grid operators who must maintain constant frequency and voltage.

Loss of mechanical inertia

Traditional fossil fuel plants provided essential rotating inertia that stabilized grids. As these plants retire, this crucial stabilizing force is disappearing.

Grid stability risks

Without adequate inertia and reactive power support, grids face increased risks of frequency fluctuations, voltage instability, and potential blackouts.

Synchronous Condensers
Power Generation Solutions

Synchronous Condensers are rotating electrical machines that resemble synchronous generators. However, they are not a generator as they are not driven by an engine or turbine. Neither are they a motor, as they do not drive a load. Instead, they are large rotating machines that adjust fluctuating conditions of an electric grid. Installed at strategic intervals along a power transmission system, Synchronous Condensers help maintain power quality.

ABB’s Synchronous condensers have been designed to meet project-specific needs in England, Australia, Canada, and Scotland. And with today’s influx of renewables, a synchronous condenser is the most secure solution to mitigate severe faults that could collapse a grid, or to strengthen a weak grid.
