Abstract :
In this paper, a PV/wind hybrid autonomous system with a battery bank as a storage subsystem is optimally designed to supply pre-specified load. The implemented design criteria is the loss of power supply probability (LPSP). For selected locations, long term data of wind speed and irradiance recorded for every hour of the day are deduced to produce the probability density function of combined generation. For considered load distribution, the probability density function of the storage is obtained and consequently the battery size is calculated to give the relevant level of the system reliability using the LPSP technique. Different combinations of PV/wind system are tested, for each the optimum size of storage facility is determined
