      There is discussion of this issue in <a
href="http://www.powermag.com/issues/features/Distributed-Solar-Challenges-Utilities-Markets-and-Regulation_5186.html"><i>Power</i></a>. 
      <i></i>A year or so ago I read an article about this topic and in
      it the conclusion was that the diversity inherent in distributed
      generation, even over a small geographic, averaged out so that the
      grid was not subject to large sudden output changes  from passing
      clouds.  The timing of when clouds shadowed different systems
      washed out the variation such that the grid did not see large
      sudden power changes. Obviously that would be different for a
      utility scale system where clouds could reduce the output of an
      entire plant in a few short amount of time. The article  may have
      been in <i>Solar Today</i>, <i>Solar Industry</i> or <i>Sun
        & Wind Energy</i>, unfortunately I can't find it now so
      maybe it was someplace else.<br>
