Solar and Wind Intermittency Firming
Ultracapacitor energy storage provides multiple benefits to independent energy generators and utilities alike, for renewable generation such as solar and wind as well as traditional fuel energy generation. 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.
The variable and intermittent power output from solar and wind generation causes dips and peaks in power output caused by cloud coverage over solar generation sites or fluctuations in wind speed for wind generation sites. Maxwell Ultracapacitors can firm power output and "ride through” these deviations, and also control the rate at which power ramps up and down to eliminate rapid power swings.
