- −41%Frequency deviation
- −70%Diesel start/stops
Summary: Virtual synchronous machines add inertia, cutting frequency deviation by 41%.
The regional grid is dominated by hydropower and leans on diesel in the dry season, with visible frequency swings. The project deploys 3 MW of grid-forming storage using virtual synchronous machine (VSG) control.
Results
- Provides inertia and voltage support to a weak grid
- Frequency deviation down 41%
- Diesel start/stops down 70%
