Energy Storage Requirements for PV Power Ramp Rate Control in Northern Europe

Figure 8

Simulated ESS maximum power requirements as functions of the ramp rate limit for (a) the 0.55 MWp and (b) 2.2 MWp PV generators. Values have been normalized to the generators nominal power. Overall trends have been depicted with the second-order polynomial fits. The results obtained by the researchers at the University of Navarra for corresponding PV generators located in western Spain are shown for comparison [9].
