Abstract

A method and system for reducing power output rate change variability. A photovoltaic power output is received from a photovoltaic array. The rate of change of the photovoltaic power output is measured. An auxiliary power source output is adjusted to limit a plant power output rate of change to within a power output rate change band when combined with the photovoltaic power.
