Frequency Response/Regulation

Frequency Response/Regulation

Ultracapacitor energy storage provides multiple benefits to microgrids/islanded grids, independent distributed energy generators, and utilities. Maxwell Ultracapacitor products are uniquely suited to deliver excellent cost of ownership value by providing a long service life and excellent reliability. Within the context of a hybrid ultracapacitor + battery energy storage solution, ultracapacitors are utilized to perform fast response functions and extend battery lifetime.

There are short term variations in grid power generation and load that lead to frequency fluctuations on the order of seconds to minutes. These fluctuations must be tracked and balanced. Maxwell Ultracapacitors can be rapidly charged or discharged in response to a generation source frequency spike (over-generation) or dip (under-generation). In some cases, customers can be paid to provide this service.

    56 Volt UPS Module

    Maxwell Technologies’ 56V series of ultracapacitor modules provide power during dips, sags in the main power source. In longer term outages, the modules provide transition/bridge power to a longer term back up source such as a motor-generator or fuel cell. For industrial applications, ultracapacitor modules provide power for graceful shutdown of process equipment.
