Applications: Renewables Integration


Energy storage can help system balance and improve the capacity factor of wind by inventorying electricity at night and acting as a shock absorber to smooth out wind ramping fluctuations.

Utility distribution engineers anticipate increasing challenges managing high penetrations of solar photovoltaics on the local distribution system. The effects of photovoltaic voltage sags and demand shifts due to cloud effects are even more severe than wind ramps because they are much faster. Energy storage systems can provide local voltage and VAR support, and manage intermittent variation in photovoltaic loads.
