Application
Supercapacitors for Renewable Energy
Wind pitch backup, PV smoothing, and microgrid power quality.
Power requirements
Wind turbines need emergency energy to feather blades on grid loss; PV and microgrids need fast power for short fluctuations.
Why supercapacitors fit
Supercapacitors can absorb and deliver high power for seconds, across many cycles, with wide temperature tolerance.
Selection factors
- DC-link voltage and power
- Ambient temperature in the nacelle or cabinet
- Service life expectations
- Monitoring and diagnostics
Limitations
- Bulk energy shifting (hours) is a battery application
Supercapacitor types
Snap-In Supercapacitors
Larger cells with snap-in PCB terminals for higher currents and capacitance.
