6 Frequently Asked Questions about “Auxiliary power consumption of energy storage system”
Do auxiliary loads affect the efficiency of battery electrical storage systems?
Abstract: The overall efficiency of battery electrical storage systems (BESSs) strongly depends on auxiliary loads, usually disregarded in studies concerning BESS integration in power systems.
What is auxiliary power consumption?
A typical auxiliary power consumption profile of a vessel journey consists of a steady base hotel load and transient thruster use when maneuvering in harbors. The magnitude of thruster power peaks is typically at least twofold compared to the base load . One or more additional auxiliary engines must be started to supply these peaks.
How does thermal management affect auxiliary power consumption?
Thermal management of a BESS, which depends on the local climate, operational use case, and the general configuration of the system, may constitute a sig-nificant proportion of auxiliary power consumption over the life-time of a facility. In some cases, auxiliary loads may be accounted separately from eficiency losses if served by an external feed.
What is the electricity cost for auxiliary loads?
The electricity cost for auxiliary loads depends on the energy consumption (kWh) and the pricing structure set by independent system operators or utilities. For example: In ERCOT, the BESS auxiliary load must be metered separately from energy used for battery charging and is charged at the retail rate.
What is the rated voltage of auxiliary power supply?
For example, the rated voltage of the auxiliary power supply might be 400V, 480V, or 208V.
