What the new grid code means for PCS selection
Stricter LVRT, primary frequency response and harmonic limits — check them when choosing a PCS.
The updated grid code raises the bar for the grid-support capability of storage converters. Low-voltage ride-through, primary frequency response and harmonic limits have all been revised.
Selection advice
When sourcing a PCS, verify the LVRT curve, frequency response time and THDi figures, and request third-party test reports.
- LVRT: longer zero-voltage ride-through
- Primary frequency response: faster reaction
- Grid harmonics: tighter THDi limits
