Reduction in solar radiation fluctuation by spatial smoothing effect
19th European Photovoltaic Solar Energy Conference, page 2900--2903. (2004)
Abstract
This paper discusses the fluctuation of power output from multiple
PV systems as a result of the variation in incident solar radiation.
The reduction in power output fluctuation is analysed for spatially
dispersed PV systems, consistent with large-scale implementation,
and for different time periods. The correlation of solar radiation
for different locations with respect to the distance between them
is investigated. This paper also discusses a cluster model to represent
very large numbers of small, geographically dispersed PV systems,
which vary in their system size, orientation, tilt angle and balance
of systems parameters. The cluster model has been used to study the
power output fluctuation and standard deviation as a function of
season. This study was carried out for UK locations but the method
can be applied to other countries to study the potential effect of
large numbers of dispersed PV systems. Keywords: solar radiation,
grid connected, modelling
