Competitive Energy Storage And The Duck Curve Richard Schmalensee1 Massachusetts Institute of Technology ABSTRACT Power systems with high penetrations of solar generation need to replace solar output when it falls rapidly in the late afternoon – the duck curve problem. Storage is a carbon-free solution to this problem.

Frequency is a crucial parameter in an AC electric power system. Deviations from the nominal frequency are a consequence of imbalances between supply and demand; an excess of generation yields an increase in frequency, while an excess of demand results in a decrease in frequency [1].The power mismatch is, in the first instance, balanced by changes in

These factors lead to different operating conditions that require flexible resource capabilities to ensure green grid reliability. The ISO created future scenarios of net load curves to illustrate these changing conditions. Net load is the difference between forecasted load and expected electricity production from variable generation resources.
The monthly load curve can be obtained from the daily load curves of that month. For this purpose, average values of power over a month at different times of the day are calculated and then plotted on the graph.
