Inverter-Based Resources

Where this fits

How power-electronic interfaces change the behaviour of solar, battery and some wind resources.

Core system ideas

Inverter-based resources connect through power electronics rather than directly through synchronous rotating machines.

Their controls determine important behaviour during voltage and frequency disturbances.

As penetration grows, accurate models, ride-through performance and system-level coordination become increasingly important.

Interfaces and tradeoffs

Modernization layers sensing, communications, software and power electronics onto the physical grid. Those additions create new capabilities as well as lifecycle, interoperability and cybersecurity dependencies.

What organizations measure

Output, voltage/frequency response, ride-through, model validation and availability.
