Energy Management System (EMS)
Get more from your batteries. ULSTEIN EMS cuts fuel use and generator wear and keeps power stable, on hybrid newbuilds and battery retrofits.
Use your batteries to save fuel and protect your generators
Hybrid power only saves fuel when generators and batteries work together. Without smart control, generators run at inefficient loads and wear out faster, and a tripped generator can still cause a blackout.
ULSTEIN EMS manages your generators and battery storage as one system. Peak shaving and load smoothing keep generator load steady. Batteries act as a spinning reserve, ready to take over instantly if a power producer trips. When conditions allow, you can run on battery power alone and charge from shore power.
The system works with ULSTEIN PMS, switchboards, battery converters and battery management systems, all from the X-CONNECT® interface. It handles simple and complex power systems on small and large vessels. You can configure it to meet your class society’s requirements.
Adding batteries to an existing vessel? ULSTEIN EMS fits battery retrofits as well as hybrid newbuilds.
Selected features
- Peak shaving
Reduces load variations on power producers, extending generator life and cutting fuel costs.
- Load smoothing
Shaves variations around the load average to protect equipment and maintain stable grid frequency.
- Spinning reserve
The energy storage system (ESS) acts as instant backup power if a power producer trips, preventing a blackout without the need for additional power capacity online.
- Charging and discharging mode
Full control of charging and discharging of ESS, configurable to operational requirements and grid conditions.
- ESS mode
Runs the vessel on ESS power alone, with other power producers offline.
- SOC compensation mode
Keeps the ESS state of charge (SOC) at the desired setpoint.
- Boost mode
Increases power stability by helping slower power producers by boosting during challenging operations.
