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

Figure 2

Measured point irradiance, simulated power of 0.55 and 2.2 MWp PV generators, and the grid feed-in power of the 0.55 MWp PV generator complying RR limit of 3%/min during 18 minutes on 29.06.2012. Irradiance has been normalized to STC irradiance and power to the corresponding PV generator nominal power.
