As renewable penetration climbs, grid “strength” is being redefined. In renewable hubs and remote grid edges, short‑circuit ratios (SCR) can plunge to 1.1 or lower. Conventional grid‑following PCS, which rely on external voltage and frequency references, become prone to oscillations, instability, and disconnection in such weak environments.

Stabilising these grids demands more than raw power—it requires the ability to actively build the grid.

East’s 1725kW Enhanced Grid‑Forming PCS delivers exactly that.

Adaptive from SCR 1.1 to 10
Real‑time grid sensing enables seamless, millisecond‑switching between grid‑following and grid‑forming modes, automatically optimising performance for any condition.

Continuous Fault Ride‑Through at SCR < 1.1
True resilience is proven under sequential disturbances. This PCS remains stable through repeated voltage sags and faults—no trip, no loss of support.

300% Overload for 10 Seconds
In the critical seconds after a fault, it delivers full active/reactive/apparent overload capacity, providing instant voltage and power support to stabilise the system and buy recovery time. Black‑start and frequency regulation capabilities further ensure robust grid restoration.

Multi‑Mode Flexibility
Supporting PQ, VF, SVG, and VSG modes, it adapts seamlessly to on‑grid, off‑grid, microgrid, and renewable base applications.

Grid‑forming is fast becoming the new benchmark for energy storage—moving from energy shifting to active grid support. With its adaptive SCR range, continuous fault ride‑through, and exceptional overload capability, East’s 1725kW PCS offers reliable, intelligent support for ultra‑weak grids, enabling higher renewable integration with greater resilience.

From following to forming—East continues to advance grid‑forming technology, powering the new energy system with safer, smarter storage solutions.
