Leveraging our vast experience in rotating machine technology
The global energy mix is changing, with more clean renewable energy sources being added to the grid. The intermittency of renewable energy sources has raised clear challenges to grid integration and its stability.
GE’s Rotating Stabilizer solution provides a CO2 free and cost-effective solution to replicate the synchronous inertia response provided by traditional thermal power generation.
Efficient and reliable synchronous inertia
GE’s Rotating Stabilizers are high-inertia rotating machines that can support the grid network in delivering efficient and reliable synchronous inertia and can help stabilize frequency deviations by generating and absorbing reactive power.
Rotating Stabilizers can help reduce emissions and maintain grid performance by providing the same synchronous inertia as coal or gas power plants without the associated CO2 emissions and high running costs.
This flexible technology can be deployed as/when required by the system operator.
GE’s Rotating Stabilizers have three operating modes:
Features
EXTENDED SYSTEM SERVICES
- The Rotating Stabilizer can provide several services including Synchronous Inertia Response (SIR), Steady/Dynamic Reactive Power, (SSRP/DRP) and an option for Fast Frequency Response (FFR) with larger converters
- Supports the network grid when increasing non-synchronous penetration, and with wide scale distributed generation
- Similar grid support capabilities as a CCGT power station
- No grid disturbance with variable speed drive start.
PROVEN TECHNOLOGY
- Based upon mature hydro power generator technology to deliver high reliability and low maintenance
Benefits
CO-LOCATED DISTRIBUTED GENERATION
- Improves grid connection agreement and reduce overall costs
- Stability at point of nonsynchronous generation
- Voltage support to enable more active power
