Abstract
Optimization models can be quite powerful in identifying a pathway to
lowest cost zero-carbon energy systems. However, it is less obvious how
to invert the models to calculate the target cost and duration of
storage needed for that storage to be a significant solution. Storage is
a dispatchable and flexible resource with the ability to perform many
functions of grid support, further complicating the analysis. This paper
complements existing papers by presenting an academic study of a
simplified energy system, demonstrating a method for quantifying cost
and duration targets for storage. The simplified analysis also helps to
gain intuition about the synergistic relationship between storage and
solar energy in a location like the state of California.
