Abstract:
In today's world of enhancing the renewable energy technologies, the demands of
electricity generation from renewable energy has been increasing rapidly. Due to that,
many researchers are interested in this field and thus many studies had been done. In
this study, the hybrid photovoltaic-wind system which produced electrical energy
from both solar radiation via solar cells and wind energy by wind turbine was studied.
The insolation and wind speed data for the year 2006 had been recorded by NRG
Symphonie Data Retriever at University Malaysia Terengganu (UMT) Renewable
Energy Station. Wind data had been analyzed using Weibull distribution method. The
method for optimization sizing of the hybrid PY-wind systems presented involved the
daily load demand for a specific house. In this study, the design of optimal size of the
systems is based on the deficiency of power supply probability (DPSP), relative
excess power generated (REPG) and unutilized energy probability (UEP) .
