[RE-wrenches] solar ramp

[Kent Osterberg]

Paul,

There is discussion of this issue in /Power/ 
<http://www.powermag.com/issues/features/Distributed-Solar-Challenges-Utilities-Markets-and-Regulation_5186.html>. 
//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 /Solar Today/, /Solar Industry/ or /Sun & Wind 
Energy/, unfortunately I can't find it now so maybe it was someplace else.
