Abstract
The yearly system performance of autonomous photovoltaic–wind hybrid energy systems
with battery storage is the subject of this article. The yearly system performance is simulated
using synthetically generated solar radiation and wind speed data pared to that simu-
lated using measured hour-by-hour data. Two different synthetic weather data sets are gener-
ated: 3-day month and 4-day month, in which 3 and 4 days represent a month, resulting in a
total of 36 and 48 days for a year. The hourly varying solar radiation data are synthesised
from the clearness index value for each month. The daily constant wind speed data are syn-
thesised using the Weibull wind speed distribution model, on a monthly basis. Using two
different synthetic weather data sets, the effect of number of synthetic days on the system
performance estimation is studied. Different sequences of synthetic solar and wind days lead
to 36 and binations for 3- and 4-day months, respectively. Three bi-
nations for both the 3- and 4-day months are chosen and the system performance of an auton-
omous photovoltaic–wind hybrid energy system with battery storage is simulated using these
binations. It is shown that the yearly system performance predicted from
the 3- and 4-day synthetic data closely agrees with that obtained from the measured data,
varying only slightly for binations. 2002 Elsevier Science Ltd. All rights
