An analysis of time-dependent spatial distribution of output power
from many PV power systems installed on a nation-wide scale in
Japan
Solar Energy Materials and Solar Cells, (1997)Abstract
The time-dependent geographical diversity of electric power output
is essential to provide more rational basis for the promotion of
photovoltaic (PV) power generation systems diffusion on a large scale.
A set of regression formulae was developed to evaluate hourly global
irradiance at about eight hundred sites throughout Japan. And regional
distribution of hourly AC electricity output from very many PV stations
were estimated, assuming that grid-connected 3 kW PV power generation
systems are installed on all the roofs of detached houses in principal
towns. The smoothing effect of PV output power fluctuation was examined
in conjunction with interconnection capacity between power grids.
