Energy Storage as a Buffer
A storage buffer bridges the fast timescales the plasma cannot - transitions, unit trips, and load steps - and is part of the resilience architecture.
Why storage is not optional
Even a firm generator cannot respond in milliseconds, and a unit can trip. Storage — batteries on the DC link and, where used, other short-duration media — fills the gap between what the load demands instantly and what the machines can supply. It is a first-class part of the resilience design, not an accessory.
What storage covers
Storage handles three distinct jobs. It rides through the islanding transition, supplying power during the sub-second swap. It bridges a unit trip, covering the seconds to minutes before a standby unit picks up or load is shed. And it smooths load steps, absorbing surges so the plasma is not asked to chase them.
- Transition ride-through during islanding
- Bridging a unit trip until the +1 picks up
- Load-step smoothing so the plasma runs steady
- Grid-forming support: emulated inertia from the DC link
Sizing against the gate
Storage duration is sized against the availability gate and the redundancy plan: long enough to bridge a trip until the standby unit is online, plus margin for the transition. It is deliberately short-duration — storage bridges, redundancy and fuel provide endurance.
The direct-conversion DC link makes storage integration natural, since batteries attach to a DC bus without an extra conversion stage; duration is then chosen to bridge the specific gap between a unit tripping and the standby unit reaching load, plus a margin for the islanding transition. Because storage sits on the direct-conversion DC link, it can respond in the electronics' own timescale rather than waiting on any mechanical system, which is precisely why it, and not the plasma, is placed on the critical path for fast events.
