Frequency control for Power Grid
Inertia improvement for power grid of renewable energy
Concept
- Renewable energy such as wind & solar power has low inertia compared to the conventional energy such as fossil & nuclear.
- To cover this weakness of renewable energy source, the necessity of energy storage to supply active power is getting increased.
- Ultracapacitor is the best energy storage device for active power due to its great power density.
Technical Challenge
- Sudden load fluctuations cause temporary frequency variations, resulting in significant shocks to the grid
- Due to the lack of inertia, it is impossible for the grid to easily compensate, leading to instability of the power systems
- In the worst-case scenario, this could lead to widespread blackouts, causing damage even on a national scale
ULTRACAPACITOR Solution
- Need to provide active power for low inertia renewable energy source
- Need to supply several hundred MW of power for a few seconds, requiring a system lifespan of 20years

Hybrid ESS
Ultracapacitor + LIB : Lower the risk of fire and Increase the stability of power supply
- Installation : Europe, Korea
- Ultracapacitor’s instantaneous high-outputs cope with initial peak load, thereby reducing the loads on battery. It results in :
1) increasing the safety by lowering the fire and explosion of LIB
2) ensuring stable electricity supply during peak periods
3) increasing the life time of battery
