Abstract :
In this paper, a methodology of sizing optimization of a stand-alone hybrid wind/PV/diesel energy system is presented. This approach
makes use of a deterministic algorithm to suggest, among a list of commercially available system devices, the optimal number and type of
units ensuring that the total cost of the system is minimized while guaranteeing the availability of the energy. The collection of 6 months
of data of wind speed, solar radiation and ambient temperature recorded for every hour of the day were used. The mathematical modeling
of the main elements of the hybrid wind/PV/diesel system is exposed showing the more relevant sizing variables. A deterministic
algorithm is used to minimize the total cost of the system while guaranteeing the satisfaction of the load demand. A comparison between
the total cost of the hybrid wind/PV/diesel energy system with batteries and the hybrid wind/PV/diesel energy system without batteries is
presented.
The reached results demonstrate the practical utility of the used sizing methodology and show the influence of the battery storage on
the total cost of the hybrid system.
