22. ESS (Energy Storage System)
: System which store energy to perform useful process at a later time
Principle
∙ Store Energy in the secondary cell
(Lithium ion, lead storage battery, NaS)
Key role
∙ PMS: control & signal to PCS & BMS
∙ PCS: AC-DC conversion, quality control
∙ BMS: Battery monitor, Control power charge-discharge
∙ Battery: Power Storage
Lifetime 10~20 yrs. (approx.)
Efficiency Over 85%
Application
∙ Power Reserve/ Voltage Control
∙ Frequency Control / Aux. Power
∙ Quality & Customer Reliability ↑
∙ Renewable Energy
∙ Low Investment in T & D
Installation 6~12 Months after PO
