Voltage Sag Mitigation and Power Quality
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.
When large, fast load demands are placed on the grid, ultracapacitors can rapidly supply power to avoid voltage sag, which disrupts overall power quality.
