ESS
Energy Storage System
“This system raises energy efficiency by storing electricity
in secondary cells (LiB, NaS, etc.) and supplying when needed.”
Power ESS (Energy Storage System)
This system raises energy efficiency by storing electricity from generators in storage devices and supplying when needed.
- Chemical Storage
- Converts and saves electricity in chemical energy
(LiB, NaS, FB, etc.)
- Physical Storage
- Converts and saves electricity in physical energy
(Pumping-up, CAES, fly wheel, etc.)
LiB ESS (Lithium ion Battery ESS)
This is the only commercialized ESS among chemical storage devices, and consists of power converter, SI (System Integration) and LIB.
- Power Transformer
- Converts and controls voltage,
current and frequency
- SI
- Combines power transformer,
battery, EMS, etc. into ESS
- L I B
- Stores power generated
Shipbuilding ESS
- Reduced Peak
- Reduced power facility capacity,
delayed operation of additional generator,
improved fuel efficiency, reduced operating time
- Operation Expansion
- Converts and saves electricity in physical energy
(pump-up, CAES, fly wheel, etc.)
