Auxiliary Power Consumption The auxiliary power consumption block calculates the power requested by the auxiliaries. The cooling system essentially defines the auxiliary consumption to maintain the operation of the BESS within the accepted temperature range.
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.
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.
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.
This includes auxiliary power transformers, switchboards and cables. The auxiliary power supply circuit must be designed to meet the BESS product's technical requirements, which vary by product. For example, the rated voltage of the auxiliary power supply might be 400V, 480V, or 208V.
The battery module cooling efficiency factor (β) was found to be enhanced without affecting inlet air velocity (U) or auxiliary power usage by keeping the volume constant and adjusting St and Sl.
