Grid Stabilization
A four-year joint development was conducted to study the usage of GIGACELL? for supply/demand control when more renewable energy is implemented in the grid. GIGACELL? was installed at a substation near a 10-megawatt PV generation plant.
| Location | KEPCO Ishizugawa Substation |
|---|---|
| Rated Voltage | 576 V |
| Composition | GIGACELLComposition? (12V-177Ah) × 48 modules |
| Rated Capacity | 177 Ah |
| Battery Capacity |
|
|---|---|
| Output | 250 kW (System output with inverter connected.) |
Example of System Operation
Charging and discharging will occur when frequency exceeds or becomes lower than the standard frequency of 60 Hz respectively. At high and low SOC levels, the system will prevent over-charging/discharging of the batteries.
