Abstract The variable nature of the irradiance can produce significant fluctuations in power generated by large grid‐connected photovoltaic (PV) plants. Experimental 1 s data were collected throughout a year from six PV plants, 18 MWp total. Then, dependence short (below 10 min) fluctuation on plant size has been investigated. analysis focuses study frequency as well maximum value registered. An analytic model able to describe given for certain day is proposed. Copyright © 2010 John Wiley & Sons, Ltd.
