Energy Storage with Super Caps |

WOODWARD IDS Energy Storage with Super Caps (IESC) is a modular system, which can be connected to a system that already has a main converter with DC Bus. Energy storage is used in installations where large amounts of energy are needed for a short period of time and are then followed by longer periods in which almost no energy is consumed. This way energy storage reduces the needed energy resources and provides smaller grid operators with the possibility of supplying consumers with short-term high-energy demands. IESC base module provides 500 kVA and includes:
• Super Caps Pack (Super Caps and monitoring electronics for each capacitor)
• DC/DC or DC/AC converter for 500 kVA
• Control unit The DC/DC converter includes a closed loop control system and offers the following features:
• Limitation of output Current
• Closed loop control of output voltage
• Limitation of the power during charging period
By parallel arrangement of 10 modules, output power of up to 5 MVA can be provided
