Analysis of fluctuation characteristics of PV system according of the array configuration

Short time fluctuations of solar irradiance will become an important issue with regard to future embedded photovoltaic (PV) systems. However, when a large number of systems introduce in certain area intensively, the output of the systems will be stable by the equalization of irradiance fluctuation. This phenomenon is called "the smoothing effect" by the authors. There are three factors to which the smoothing effect smoothes the fluctuation; number of PV systems, area of installed PV systems, and PV array configuration. In this time, authors report on result of analyzing the fluctuation characteristics of each array configuration.
