Multi-use energy storage for renewable sources

This invention describes a wind power system that includes a wind turbine, a generator, and a power converter. It also integrates an energy storage device, such as batteries, connected through a bidirectional converter. The system uses an inertia controller to adjust the wind turbine's power output when the electrical grid experiences instability, and a separate controller manages the energy storage to balance power flow based on these adjustments and system conditions.

Why it matters: Filed when grid-scale battery storage was nascent and expensive. Today, battery technology has matured significantly, making the integrated energy storage and grid stabilization features claimed far more practical and economically viable for increasing renewable energy penetration.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedWind turbine, power electronics, control software
